FAQs - Sewage and Waste

The job of your silt trap is to prevent any unwanted materials, like silt, soil and sediment, from entering your water storage system. Before entering the drainage system, water is directed into the silt trap — a basin-type container that is placed in the upstream of your soakaway crate. The water is temporarily contained in the trap where the silt and sediment settles to the bottom, leaving the filtered water at the top. The invert of the pipe sits just above where the sump settles below, allowing the filtered water to continue to the drainage system, leaving the silt behind.

Without a silt trap, silt and debris would enter your water storage system and cause costly damage. If water cannot drain away you risk causing flooding and your system’s ability to remove water could be affected, clogging pipes or filling soakaway systems, reducing their capacity for holding water.

All silt traps have the same purpose — to keep a soakaway system free from silt and sediment. But different types of silt traps are better for different types of systems. The primary difference between the different types of silt traps is the size of the area covered by your system. That’s why silt traps come in a range of sizes, so make sure you choose one that is suitable for your needs. Naturally, the larger the area your water storage system is serving, the larger your silt trap should be. You will also want to consider the type of environment. At Tanks Direct, we stock a wide of car wash silt traps that offer effective silt removal for car wash facilities or any areas with particularly high silt run-off.

Silt and debris will build up in your silt trap, so it’s important that it is regularly cleaned and maintained. Failure to do so can, at best, result in them becoming ineffective or, worse, eventually lead to an entirely blocked drainage system. The ‘basket’ of your silt trap can usually be easily removed to allow you to clean it and then put it back. The instructions will vary between each silt trap so it’s important to refer to the manufacturer’s instructions.

Sump pumps are essential components of any home's plumbing system, as they are responsible for keeping the basement or crawlspace dry by removing excess water. However, like any other machine, sump pumps require regular maintenance to ensure that they are operating properly and efficiently. It is important to understand that sump pumps have a limited lifespan and, depending on the specific model, are typically expected to last up to ten years.

If you do not perform regular maintenance, the sump pump may fail prematurely, resulting in costly repairs or even a flooding incident. Regular maintenance should include checking the sump pump for any signs of corrosion or damage, such as rust or cracks, and checking electrical connections to make sure they are tight and secure. You may also want to insect your sump pump for any debris or blockages that may prevent it from working properly.

You can regularly test your sump pump to make sure it is working properly by filling up a bucket with water and placing it near the sump pump's inlet. If the pump does not turn on when the bucket is filled, you may have a problem.

Ideally, you should try and avoid running a sewage pump continuously and only run it intermittently. This lowers the risk of overloading and damage to the pump in the long run.

It's important to consider the size of the pump and the amount of wastewater it will be moving. If the pump is too small, it won't be able to handle the amount of wastewater it needs to move and will eventually burn out. On the other hand, if the pump is too large, it will be wasting energy and money to run it continuously.  Most sewage pumps are also designed to run intermittently to conserve energy and reduce costs, so keeping it running all the time is not the most cost-effective use of this product.

Vortex impeller sewage pumps use centrifugal action. In this sewage pump. the impeller rotates and causes a tornado-like action that pulls the waste into the pump and then sends it into the discharge pipe with little or no contact with the impeller which helps the pump to withstand any stringy material it may encounter. This means there is a much lower chance of clogging the impeller.

Sewage pumps are available in a few different options including effluent pumps, grinder pumps or macerator pumps and submersible pumps. Effluent pumps remove the grey wastewater that stays in your septic tank after the solids have settled and are good for residential and small commercial applications.

Grinder pumps or macerator pumps collect wastewater from your household appliances and fixtures including toilets, washing machines, and bathtubs. Grinder or macerator pumps works by the pump grinding the waste into a fine slurry before pumping it to your septic tank when the water in the tank reaches a certain level from a holding tank to collect waste. Submersible pumps are used for residential, commercial, and agricultural applications.

If you are unsure of the type of sewage pump you need, we are more than willing to help. Please give us a call or send us an email.

Used to transfer waste liquids and solids from one place to another, a sewage pump is often referred to as a submersible sewage pump since the pump is submerged most of the time. Sewage pumps have a motor that rotates an impeller to create pressure that pushes the waste into a discharge pipe. In residential applications, the sewage is generally pumped from a sewage basin to a sewer system or a septic tank. Sewage pumps can be manual, automatic or dual mode, where the pump can be used as both manual and automatic. It is not recommended to use a manual sewage pump inside of a sewage basin due to the risk of sewage overflow.

Removing the pump

1. Begin by isolating the effected pump by switching to ‘Off’ on the control panel facia. Please note: if the pumping station will be remaining in service — with the other pump working on its own — it is essential that the effected pump controls are disabled by isolating or removing fuses.
2. Disconnect the effected pump motor cables at the control panel terminals, carefully noting the terminal positions for each wire. Plug off the cable entry hole at the panel.
3. Close the control panel door and return the main isolator to ‘On’.
4. Lift the effected pump clear of the chamber using the lifting chain provided. Please check the pump weight before attempting to manual lift. If specified on ordering, lifting equipment will have been supplied. The coupling fitted to the pump permits it to be removed and refitted simply by lifting it clear with the chain, the pump assembly sliding up and down the guide rail. No manual disconnection of pipework is required, and it is therefore not necessary for personnel to enter the chamber to remove a pump for servicing.
5. Hose the pump off thoroughly.

Pump refitting

1. Check the effected pump switch on the control panel facia is still in the ‘Off’ position and switch the main isolator to ‘Off’.
2. Lower the pump back down into the chamber on its guide rail, using the lifting chain provided. When in position on its pedestal, its own weight will lock the pump discharge connection into position.
3. Re-connect the pump cable at the panel terminals, taking care to ensure the gland entry is properly re-sealed.
4. Refit or re-connect fuses as required.
5. Close the panel door and switch the main isolator back to ‘On’. Reset the pump switch to ‘Auto’ mode and check for correct operation of both pumps through a complete set of cycles in accordance with the procedures in ‘Start up’.

With the right care and maintenance, your sewage pump should last for many years. There are, however, several factors that will affect the lifespan of your sewage pump. If your sewage pump is not correctly installed to begin with, its lifespan will decrease. That is why we recommend your sewage pump is installed by a fully qualified engineer. We’d also advise that your sewage pump is regularly serviced to identify any potential issues and prevent it getting blocked. With the correct installation and ongoing maintenance, sewage pumps have the potential to last for over 30 years.

Effluent pumps are generally more efficient than other sewage pumps as they are only pumping grey water. However, the effluent pumps may not be suitable for your use. The most efficient sewage would be the one that is most suited to your application and system size. If you are unsure of the type of sewage pump you need, we are more than willing to help. Please give us a call or send us an email.

Sewage pumping stations are needed when gravity cannot be relied upon to move wastewater and sewage towards the main sewer line. Perhaps there is a lack of gravitational flow if, for example, the sewage is situated below the main sewer level and would need to be pumped upwards. Maybe the sewer is obstructed by a ridge or there is no gravity system in place. In these circumstances, installing a sewage pump station could be much cheaper and just as effective as installing a sewage system with gravitational flow.

You’ll find many advantages to having a sewage pump station installed at your property. They can be fitted with alarms so that you will be notified if there are any problems with the system. Sewage pump stations also work automatically so there is minimal human contact. This reduces the risk of health issues.

Your sewage pump should not run constantly. Usually it should run from 10 to 15 seconds until the float switch detects the water level has dropped adequately. It will then cut off. If your sewage pump is running constantly it may need to be serviced, repaired or replaced. The average life expectancy of a sewage pump is about 10 years.

You may need to service or replace your sewage pump is you find the following: -

• If the water at the discharge point is dirty or brown
• The pump is not working at all or sounds like it’s struggling to pump
• Your pump is constantly running and doesn’t switch off even though no one is using the facilities in the building
• Sewage is backed up into the building
• There is a smell of sewage
• There is no fluid emptying from the holding tank
• There is no power to the pump

If you do require a Service, please give a ring to arrange.

Yes, it is cost effective to get your sewage pump regularly maintained to lengthen the life of the pump. Typically pump servicing will include: -

• Cleaning out the sump chamber
• Cleaning of pumps and float switch
• Electrical test of pumps and all floats
• Checking all cables for damages and general wear

SuDs stands for Sustainable Drainage Systems. They are systems designed to be environmentally beneficial, to ensure minimal or no long-term detrimental damage to the surrounding environment. It is a term used to describe control strategies or products that allow the efficient and sustainable drainage of surface water, to help minimise pollution and manage the impact on water quality in local water bodies.

SuDs help to manage surface rainfall run-off by controlling the rate and volume of the runoff. This helps to relieve pressure on sewerage systems, imitating natural drainage as closely as possible. SuDs can help local authorities, planners, architects, and developers deliver greener infrastructure.

Sustainable drainage systems (SuDS) present an opportunity to add value to a project, while meeting local planning requirements around increasing sustainability and managing flood risk. They can help save you time and money but that’s not all.

SuDS reduce the impact of urbanisation on flooding, by managing runoff and flow rates from hard surfaces. They provide opportunities for using runoff where it falls, such as rainwater harvesting, that in turn helps to reduce both the flow into sewers and our dependency on mains water. Some SUDs can help to reduce pollution, protecting the quality of downstream water bodies such as streams, rivers, lakes, bathing, or shellfish waters. They preserve the natural flow regimes in watercourses and, by being sympathetic to the environment and the needs of the local community, create better places to live, work and visit. Urban watercourses can provide an attractive habitat for wildlife, as well as providing opportunities for evapotranspiration from vegetation and surface water.

Bypass and full retention separators

Sometimes known as petrol interceptors, bypass and full retention separators are designed to manage runoffs and spills, whether that’s from large amounts of rainfall or the accidental spillage of oil or fuel. These separators will protect your local environment from pollutants and help reduce the risk of large fines from the Environment Agency. Full retention separators are used when there’s a medium to high risk of contamination caused by spillage or flooding, for example in large car parks, industrial workshops, and recycling centres. Bypass separators are used when the area has a low risk of contamination, such as roadways or commercial areas that would only get light contamination. It can cope with water flow generated by rainfall up to 6.5mm per hour.

Domestic rainwater harvesting

Rainwater harvesting is an eco-friendly way of reducing water usage in your home. There are two types of systems available – direct and in-direct. In a direct system, harvested water is pumped directly to the appliances, whereas in an in-direct system, the harvested rainwater gets stored in a holding tank and gravity feeds the appliances. The harvested water can be used for a variety of appliances, including toilets, showers, baths, sinks and washing machines.

Surface water treatment separators

 Surface water treatment separators (SWT) reduce pollution in line with SuDs Mitigation Indices by removing metals, hydrocarbons, and suspended solids from surface water. Our SWTs are lightweight and easy to install and can be maintained and serviced from ground level.

Vertical and horizontal flow control solutions

 Designed to control the flow of water into local watercourses, flow control solutions reduce the risk of flooding on natural habitats and prevent bank erosion.

Vertical and horizontal pump stations

Used in housing estates, hospitals, and commercial sites, sewage pumping stations transport sewage or wastewater when gravity cannot naturally carry it, such as where a sewer line may travel up an incline or over a ridge. They work by collecting wastewater and storing it in a chamber. When the chamber is full, a high-pressure integral pump lifts the sewage through a discharge system before pumping it into a sewage treatment works.

Recognising signs early that your septic tank is full and in need of emptying is essential to maintaining the health of your septic tank system. One noticeable sign that your septic tank may be getting full is slow drainage throughout your plumbing fixtures. You might notice that sinks, showers, and toilets are slower to drain than usual. Water may back up or gurgle in drains, indicating that your septic system is struggling to handle the volume. As the tank fills, it has less capacity to contain and treat the waste properly, so you may notice foul odours in and around your property. The most inconvenient and obvious sign of a full septic tank is sewage backups inside your home. If toilets or drains are consistently backing up or becoming clogged, it's a clear indication that your septic tank is overloaded and needs immediate attention.

Another indicator is a vibrant, lush patch of grass or vegetation over your drain field. When the tank reaches its capacity and cannot properly process wastewater, the excess effluent may fertilise the surrounding soil, causing grass and plants to thrive more than usual. Standing water or soggy areas in your garden, especially around the septic tank or drain field, can also signal that your septic tank is full or experiencing issues. This pooling occurs when the tank is unable to absorb and distribute wastewater efficiently. If you notice these wet areas persisting, it's essential to address the situation promptly to prevent further damage to your septic system.

Under Environment Agency Septic Tank General Binding Rules, if your septic tank discharges into surface water, like a stream, river, ditch, surface water drain etc., it should have been replaced with a full sewage treatment plant by the 1st January 2020. By not carrying out the replacement, you could be liable to a hefty fine.

At Tanks Direct we stock a wide range of sewage treatment plants from leading manufacturers including Klargester Biodisc, Klargester Biotec and Harlequin Hydroclear. A sewage treatment plant removes contaminants from wastewater using the growth of bacteria to break down the sewage. They produce cleaner and more environmentally friendlier effluent. Domestic sewage treatment plants are the perfect alternative when it isn’t legal to have a septic tank.

Rainwater must not enter your septic tank. Make sure that the downpipes and drains that carry rainwater are not connected to your septic tank. Your tank is sized to deal with a specific volume of wastewater – ensuring the sewage remains in the septic tank long enough for all the solid waste to settle at the bottom. If rainwater enters the tank, the flow rate increases, and adequate settlement does not occur. As a result, the effluent would contain so many suspended solids that it would very quickly compromise the soakaway, and the contents of the tank will be washed out before they’ve been broken down, causing pollution and health hazards. Septic tanks and sewage treatment systems must only be connected to grey and black water drains, such as toilets, sinks, showers, baths, washing machines, and dishwashers. If you’re looking to manage rainfall and surface water, consider installing a rainwater harvesting system. 

A cesspool (sometimes called a cesspit) is just a holding tank for wastewater. It only has one pipe connection fitted, that lets the waste into the tank. There is no treatment of the waste, so the sewage just builds up in the tank and needs to be emptied by a sewage disposal tanker every month or so (depending on how big the cesspool is and how many people are using it).

 A septic tank is a step up from a cesspool. A septic tank has two pipe connections - one for the inlet, that lets wastewater in, and an outlet, that discharges treated wastewater into a soak away. Like a cesspool, a septic tank will need to have sludge emptied by a disposal tanker, but not at the rate of a cesspool. Septic tanks are a much better and cleaner sewage system. They treat the waste, so it can safely interact with our environment and require emptying less often, saving you money.

Septic tanks, when properly maintained, can serve you well for several decades. A well-constructed septic tank can last anywhere from twenty to forty years or even longer, making it a worthwhile investment for your property. But to maximise the lifespan of your septic tank, you should schedule routine inspections and emptying. This preventative maintenance helps remove accumulated sludge and scum, preventing them from clogging the system and causing damage. Neglecting these maintenance tasks can drastically reduce your septic tank's lifespan, leading to costly repairs or replacements sooner than expected. You should avoid flushing non-biodegradable items, excessive grease, or chemicals down the drain, as these can harm the system and lead to premature deterioration. Educate yourself and your household on septic-friendly practices to ensure your system remains in good working condition for many years to come.

The type of soil and climate in your area may also impact the lifespan of your septic tank. In areas with dense clay soils, for instance, the tank may fill up faster. Harsh weather conditions can also affect the tank's structural integrity, so it's essential to take these factors into account and adapt your maintenance schedule accordingly.

A septic tank is the first stop for the wastewater that leaves your home. The waste is held in the tank, where it goes through the process of separating the solids from the liquids before filtering water into your drainage field. The best type of septic tank for your house will depend on several variables – from your property’s square footage to the number of bedrooms and number of people using the system.

The larger your house, the larger septic tank you’ll probably need. And the more occupants in your home, the bigger the tank you’ll need. A small septic tank will probably suffice if you only have two people living in your property – but if you have a large family, of five or more people living in your home, you’ll need a larger septic tank to manage all the household waste hygienically and effectively.

It's also important to consider the following: Do you have two kitchens? Or multiple bathrooms and ensuites? Do you have, or plan to have, a hot tub or a swimming pool? All of these will increase the demand on your septic tank.

There are three types of septic tanks: the more traditional masonry-built pits, Low profile units or modern fibre glass units, often referred to as “onions”. Regardless of their type, septic tanks all function the same way. There is a settlement tank where the sewage and waste is held for a length of time, while naturally-occurring, waste-degrading bacteria breaks down the organic matter in a process called anaerobic decomposition. The final effluent from the septic tank is then drained into an underground soak away system.

In an onion shaped septic tank, the tank is split into three vertical segments. Wastewater enters the septic tank’s first chamber and is held there. This gives the waste material time to separate, with solids and sludge settling at the bottom of the tank and other lighter waste floats to the top. The naturally occurring aerobic (waste-degrading) bacteria breaks down the waste in the tank, reducing the volume of solid waste. The liquid in-between flows through into a second and third chamber, where further settlement occurs. Finally, the effluent exits to the soak away on the other side of the tank.

It is important to ensure your soak away is an adequate size to efficiently handle the volume of effluent from your septic tank.

There are 3 options available:

(1) Connect to a main sewer if possible
(2) install a drainage field or
(3) install a sewage treatment plant which treats the wastewater, producing a clear overflow that is environmentally friendly and suitable for discharging.

If you’re thinking about installing your septic tank yourself, think carefully. Although hiring a specialist contractor may seem pricey, an incorrectly installed septic tank can leave you in a nasty mess; both physically and legally. Incorrectly installed septic tanks can cause serious drainage issues, that can be extremely costly to fix. An installation by a professional contractor is highly recommended and will give you complete peace of mind, knowing your septic tank is suitable for your needs, in good working order and legally compliant.

If you have the skills and experience to install a septic tank yourself, the following offers a very basic guide to installing a septic tank system. However, professional advice should always be sought to fully understand the legalities of installing your system, and the manufacturer’s guidance and instructions should always be followed carefully.

Prepare

Ensure you have the correct Building Regulations approval, and you have your consent of discharge from the Environment Agency. Read the full installation guide provided by your tank’s manufacturer. Check your tank on delivery and ensure the depth of your incoming pipework is suitable for the tank. Have a pump available to keep excavation free from rising groundwater during installation.

Install the tank

Dig a hole that is big enough for the tank and any recommended backfill. Please refer to the manufacturer’s installation guide, considering the drainage falls required. Ensure the tank is level and has a solid base to sit on. Check that the inlet and outlet orientation is correct, before backfilling with whatever material the manufacturer advises, and lay the pipes for your drainage field.

Connect the pipes

Once everything is in place, connect the tank inlet to the drainage pipe from your house and the outlet to your drainage field. Consult a qualified plumber if you are unsure.

Within the tank, there should be lots of bacterial activity, digesting the organic waste in the effluent layer and sludge layer. The rate of digestion is dependent on the bacteria present, the amount of oxygen and the amount of inbound wastewater. If the bacteria can’t keep up digesting the organic material in the wastewater, two things happen. Firstly, there will be a build-up of sludge that will require pumping out. Secondly, undigested effluent waste in the middle liquid layer will flow straight into the soak away, increasing the chances of soak away drainage and blockages.

If your septic tank system is not in good working order, it can be a serious risk to both health and the environment. You also have a legal responsibility to maintain your septic tank system. In looking after your septic tank, it will have to be emptied less frequently, and this will save you money. A septic tank system can also be costly to replace if it fails.

Follow these key steps to keep your septic tank system healthy:

1. Don’t overload the tank
   Consider how much waste might be running into the tank in one go. If you have multiple showers running at the same time, as well as the washing machine and the dishwasher, the tank will be receiving a significant amount of liquid in one go. While that liquid may not hold excessive amounts of organic waste, it could stir up the waste in the tank, mixing sludge and scum into the clear water middle layer, which will then overflow into the drain field and soak away. Be mindful and try to balance what flows out into the tank, as much as possible, throughout the day.
    
2. Reduce the amount of water you’re using
   Not only will this lower your water bills, reducing the volume of water you use will improve the performance of your septic tank system. There are several ways to do this:

• Consider more efficient toilet cisterns
• Use plugs in sinks and basins
• Take shorter showers/use less bathwater
• Use eco settings on washing machines and dishwashers

Think about what you’re flushing

Sanitary products, wipes and cotton buds contain plastics in some shape or form, and the good bacteria in your tank can only digest organic waste. Therefore, you must never flush these types of products. Harsh chemical products, like bleaches and paint strippers, are going to kill the bacterial population in your tank, resulting in poor waste digestion and will negatively affect your septic tank performance. Fats, oils and grease may create blockages and are a major component of scum layers on the surface of the tank.

• Don’t flush anything other than bodily waste and toilet paper down the toilet
• Don’t dispose of grease or oil down any drain – wipe out pans and pour fat into a container to be disposed of in the bin
• Don’t put paints, solvents or chemicals down the drain
• Don’t try to unblock pipes with caustic soda or drain cleaners. Try boiling water instead
• Don’t connect rainwater pipes to your septic tank

To keep your septic tank performing as well as possible, we recommend you have it emptied regularly. This will reduce the risk of a build-up of sludge, which can lead to problems with your system. This could be anything from an unpleasant smell to a complete system failure. It can be tricky and expensive to fix issues with your septic tank, so make sure you get the tank emptied regularly and before these issues occur, and make sure the company you use to empty your septic tank is registered to do so.

Of course, how often it should be emptied will depend on several factors including the size of your septic tank (a small one will need emptying more often than a larger one), the number of people using the system and what you are flushing into the septic tank.

It is important that you recognise the signs that your septic tank is full – to save you money, stress, and ensure that your environment is kept safe. Here are some signs that may indicate your tank is full:

• Wastewater overflows into the drainage area, and you see pools of water appearing near your septic tank.
• Water starts to drain away slowly from sinks, drains and toilets.
• You notice nasty odours.
• Grass above the septic tank or drainage area is especially green as there is a lot of water around.
• Sewage begins to back up as the wastewater has nowhere to go. This is the worst, and most expensive way, to find out your tank is full!

If your septic tank system is in good working order you should have the following:

• Your household drainage should be quick to clear, and toilets should not be backing up
• There should be no smell from your tank and the cover should be accessible and well fitting
• The soak away should be dry not swampy, smelly or have prolific grass growth
• A pale liquid with little or no smell should come from the discharge pipe. It should not be dark, smelly or contain solids
• Makes sure to keep deep-rooted trees and plants at least 30 m away from your system. Keep the grass nearby short.

If any of the above is showing signs that your septic tank system is not in proper working order, you must get it repaired or replaced by a credited installer.

You should have your septic tank system regularly maintained in accordance with the manufacturer’s instructions. If these are not available, ask your local maintenance company for advice. This will save costly repairs or replacement of the sewage system in the long term.

If your tank does not comply with the “General Binding Rules” you must apply for a permit. To see the General Binding Rules go to https://www.gov.uk/guidance/general-binding-rules-small-sewage-discharge-to-a-surface-water

Different areas of Great Britain have different requirements: -

• England – No charge
• Northern Ireland – Yes, a charge applies
• Scotland – Yes, a charge applies
• Wales – Yes, no charge applies in most cases

If you own a property which you rent, or you are a tenant yourself, it can become a little less clear who has the responsibility to empty the septic tank. Maintenance and responsibility can be written into the tenancy agreement. If you are a landlord renting out a property with a septic tank you may need to put measures in place if you want the tenant to take responsibility for the septic tank. You may need an inspection or service after the end of any tenancy period. As a tenant, if it is written into the tenancy agreement that you have responsibility for the septic tank, you might also want to insist upon an inspection to ensure you aren’t inheriting any issues you would then be liable to pay for is one way to do this. Checking the schedule of maintenance and the obligations is another before any serious issues can occur. Following the guidelines of the septic tank is important too.

Septic tanks should be at least 7 metres away from any dwelling. They should also be located within 30 metres of an access point so that the tank can be emptied.

If you sell a property with a septic tank that discharges directly into a watercourse, you should agree with the buyer who will be responsible for replacing or upgrading the treatment system. You should agree this as a condition of sale. You must also provide the buyer with a description of the treatment plant and drainage system, the location of the main parts of the treatment plant, the drainage system and discharge point, how the treatment plant should be maintained, and any details of any changes made to the treatment plant and drainage system while you were the owner of the property. You’ll also want to give the new owners the maintenance manual and maintenance records if you have them.

Selling a property without a septic tank installed or with a septic tank that is non-compliant with the government’s general binding rules will not only detract potential buyers but may also be subject to enforcement action by the Environment Agency. You can find details of the latest regulations surrounding septic tanks on the government’s website.

If your current system discharges directly into a water course, you will need to upgrade your system. To go through your options give us a call, and we can talk you through the various options.

Making up between 50 to 80% of a household’s wastewater, greywater is a term given to the relatively clean wastewater from baths, sinks, washing machines and other kitchen appliances. It is generally any water that is drained from the house except toilet water. It may contain traces of food, grease, hair, dirt and household cleaning products, but it does not contain urine or faecal matter, which would be classified as blackwater as it contains harmful bacteria and disease-causing pathogens. There are ways to capture and reuse greywater, for activities like watering the garden and flushing toilets. There are simple kits that can divert greywater from your down-pipe if it is easily accessible.

Greywater and rainwater are not the same. Rainwater is fresh precipitation straight from the sky. It is naturally pure and free from salts, chemicals, detergents and minerals. Greywater is once-used household water that comes from washing machines, baths, showers and sinks. It may contain traces of food, dirt, grease and household cleaning products, so is less ‘clean’ than rainwater. It contains bacteria and a nutrient source and, as it is often discharged warm, is an ideal environment for pathogens to multiply.

Because of this, it is not recommended that greywater is stored. It is best directed to a soakaway and released a couple of inches below surface level. Rainwater, however, is relatively clean and can therefore be safely stored for long periods of time.

A greywater pump pushes wastewater from baths, showers, washing machines, and dishwasher into your property’s wastewater system. Greywater pumps are designed to eliminate grey wastewater safely and effectively, pumping greywater away from your home.

Greywater is household wastewater that comes from showers, washing machines, baths and bathroom sinks. It is once-used water that has been in contact with humans and their germs. Even if it is treated, greywater has the potential to carry bacteria and viruses and is never going to be safe to drink. There are some ways to reuse your greywater, however — for flushing toilets, laundry and watering your garden, for example. The plumbing from most buildings directs all wastewater (greywater and blackwater) to the sewer. But if greywater is separated out from the more polluted blackwater that comes from toilets, it can be treated and used as an alternative source of water for non-potable purposes.

You will need a wastewater tank on your property if you are unable to connect to a public sewer. If you're thinking of installing a wastewater tank on your property, we'd advise you to start by researching the suitability of sewage treatment plants, septic tanks and cesspools to get an understanding of how they work and their individual benefits and limitations. If you need any help or advice, please feel free to call our friendly team. We can help with advice on which treatment plants will be suitable for your situation and advise you on whether they require any planning permissions or permits to install.

If you are unable to connect to a public sewer, building regulations state you’ll need a sewage treatment plant, septic tank or cesspool to manage wastewater.

Cesspools hold sewage in a tank with no outlet or facilities to treat the waste. When the tank is full, the waste needs to be collected by a lorry tanker and taken away for disposal. A cesspool may suit you if the ground is unsuitable for wastewater to soak away or if the site is close to a drinking water supply. They are generally a cheaper option to get installed. Be warned though, the wastewater inside your tank is not treated and having the waste collected regularly can get pricey. You should also note that cesspools are banned in Scotland and used usually only as a last resort in the rest of the UK.

Sewage treatment plants, on the other hand, treat your wastewater by creating an environment that allows waste-degrading bacteria to flourish so that you can discharge your treated waste into a ditch or stream. They are affordable, clean and treat sewage so that it has minimal impact on the environment. They do, however, require regular maintenance and an electricity supply.

Septic tanks use a multiple tank system that separates the wastewater into solids and liquids. They can treat and discharge the liquid part of the sewage, leaving the solid waste requiring collection and disposal by a tanker. These are ideal for small developments or single dwellings. You’ll need to ensure you have a drainage field or mound that is porous enough for the liquid effluent to percolate as septic tanks can no longer be discharged into a watercourse under new UK laws. They are cheap to install and only require desludging once or twice a year.

When determining the type of wastewater tank you need as a homeowner, several factors should be considered. For more information on which tank is right for you, please click the following link to see our homeowners guide, on what type of wastewater tank you might need.

 A cesspool, also known as a cesspit, is an underground tank that collects wastewater and sewage. There is no outlet to disperse the waste or facility to treat it — it simply stores wastewater and sewage until it is collected by a tanker and taken away for disposal. They typically have a manhole for access and the only piping is to release gasses which accumulate in the tank. The contents of your cesspool must be removed regularly. How often will depend on the size of your tank and how much wastewater you are producing, but typically you will want your cesspool emptied by a licensed waste handler every month.

You may need a cesspool if your property is not connected to a public sewer network or for holiday homes, camp sites and places where the discharge of effluent into the ground is not possible due to unsuitable soil conditions. You do not need a permit to install a cesspool unless the Environment Agency tells you that you do and they do not have to comply with the general binding rules that apply to septic tanks. However, you will need planning permission and building regulations approval to install your cesspool.

 A septic tank is buried underground, just like a cesspool. Unlike a septic tank however, a cesspool does not process or treat wastewater and sewage — it simply stores it. Septic tank systems treat the wastewater, treating the liquid wastewater so that it can drain away into a stream or soakaway. The system is simple but effective — wastewater enters a chamber where solids can settle and decompose at the bottom. The liquid at the top flows into a second chamber where any finer remaining solids are removed from the liquid and through to the soakaway. Solid waste from septic tanks will occasionally need collecting by a licensed disposal specialist, in much the same way as a cesspool, but much less often. That’s why having a cesspool can become quite costly long-term as waste disposal services don’t come cheap. Cesspools are also a less eco-friendly choice as untreated effluent could overflow into the surrounding environment. Septic tanks are safer as the wastewater is treated. 

Cesspools are usually used as a last resort or for temporary drainage situations. You may need a cesspool if your property isn’t connected to the public sewer network and where discharging effluent into the ground is not possible, such as holiday homes and camp sites. Cesspools do not have to comply with general binding rules that apply to septic tanks and you won’t need a permit to install one unless the Environment Agency tells you otherwise. It is important, however, to obtain planning permission and building regulations approval to install your cesspool.

For septic tanks, the recent changes in regulations state that they can no longer discharge into surface water, for example streams, rivers, ditches, drains etc. and if yours does you should replace it immediately with a full sewage treatment plant under Environment Agency Septic Tank General Binding Rules. As of 1st January 2020, all septic tanks that discharge into waterways must be either replaced, using sewage treatment plants with full BS EN 12566-3 documentation, the discharge to the waterway impeded and redirected to a drain field, designed and made according to the up-to-date British Standard BS6297 2007.

A sump pump serves as a crucial guardian for your home, especially in areas prone to flooding or excessive moisture. Nestled in the lowest part of your basement or crawlspace, the primary function of a sump pump is to prevent water accumulation and potential flooding. It achieves this by actively collecting excess water that could seep into your home's foundation and directs it away from the property.

The heart of the sump pump system is the sump pit, a specially constructed basin that collects water. When the water level in the pit reaches a certain height, a float or pressure sensor triggers the pump into action. The pump then swiftly removes the water from the pit and directs it away from your home through a discharge pipe, usually leading to a storm drain or a designated area that prevents water from re-entering your property.

Beyond preventing flooding, a sump pump is a valuable defence against mould and mildew. By swiftly removing excess water, it reduces the risk of moisture seeping into your home's foundation and creating a breeding ground for these harmful substances. This not only protects your property but also promotes a healthier indoor environment for you and your family.

The electricity consumption of a sump pump is a common concern for homeowners, but the actual usage can vary based on factors such as pump type, capacity, and frequency of operation. Generally, sump pumps are not known for consuming a significant amount of electricity. Submersible pumps, which are more commonly used in residential applications, are typically energy efficient. The power consumption of a sump pump is measured in watts. A typical submersible sump pump might use around 500 to 750 watts. However, it's crucial to note that sump pumps are designed to operate intermittently. They kick into action when the water level in the sump pit rises to a certain point, usually triggered by heavy rainfall or melting snow. Once the water is pumped out and the pit is clear, the pump shuts off. This on-and-off cycle helps minimise continuous electricity consumption. If you live in an area prone to heavy rainfall or have a high-water table, your sump pump may operate more frequently. However, for many homeowners, the pump might only run a few times a month or even less, resulting in modest electricity usage. Regular maintenance, including cleaning the pump and ensuring proper functioning of the float switch, also contributes to energy efficiency by allowing the pump to operate optimally.

No, a sump pump should not run continuously throughout the day. Sump pumps are designed to operate intermittently, turning on only when the water level in the sump pit rises to a certain point. Continuous operation may indicate a problem with the pump, the float switch, or an unusually high water inflow that requires investigation.

A constantly running sump pump can be a sign of an overwhelmed drainage system, a malfunctioning float switch, or a pump that is too large for the intended application. If your sump pump runs continuously, it's crucial to assess the situation promptly to prevent potential issues such as motor burnout, increased electricity consumption, and unnecessary wear and tear on the pump components.

If you notice that the pump is running more frequently than usual or appears to be struggling to keep up with water inflow, it's time to investigate. Check for any visible leaks, assess the condition of the pump, and ensure that the float switch is functioning correctly. Additionally, examine the drainage system and discharge pipe to confirm that water is being directed away from your home effectively. Remember, a well-maintained and properly functioning sump pump is crucial in safeguarding your home from potential flooding and water damage.

A basement sewer pump usually needs to be installed then your sewer line level is below the main sewer system. The pump collects the wastewater from your basement bathroom or toilet into a tank and, when the sewer pump is turned on, the motor rotates creating a centrifugal force that pushes the wastewater into the impeller. It is then discharged into the main sewage network or a septic tank.

Sump pumps are the same as basement drainage pumps. They are used to remove water that has accumulated in a water-collecting basin and then pumped to the nearest drainage point. Sump pumps are commonly found in basements that are below ground level.

With good and regular maintenance, your basement pump should last for many years. There are several factors that will affect the longevity of your basement drainage pump. Regular and intense use will affect the lifespan of your basement pump, so if you have a below ground property with a high level of water ingress, your basement drainage pump is likely to be in a state of constant use. Like any machinery, the more it is in use the quicker its lifespan will decline. Equally, if your basement has been fitted with a pump that is too small, the pump will have to work much harder, shortening its lifespan. It’s also important that your basement drainage pump is installed correctly — if the motor doesn’t engage properly or the connection to the piping isn’t quite right, you could find that your pump works itself to an early grave. A lack of maintenance can also negatively affect the lifespan of your basement pump so keep a regular maintenance schedule to ensure your pump stays healthy.

A domestic sewage treatment plant works by breaking down solid waste to produce a cleaner, more environmentally friendly effluent. Wastewater and sewage are supplied to the primary tank, where the solids separate and from the liquid and then flows into the biozone chamber. Here, a pump airs the waste and friendly bacteria is used to condense the organic matter, breaking it down. When the waste leaves the final waste chamber, it is 95% clean and ready for dispersal into soak away systems, subject to consent from the relevant environmental agency.

A well-designed and properly maintained sewage treatment plant can have positive environmental impacts by reducing water pollution and protecting aquatic ecosystems. However, if not properly managed, a sewage treatment plant can also have negative impacts such as odours, noise pollution and emissions of greenhouse gases.

Domestic wastewater treatment plants use natural biological processes to break down sewage and safely process harmful compounds. This reduces pollution and is vital for protecting the local flora and fauna.

Maintained in accordance with the manufacturers recommendations, most modern treatment plants have a long lifespan and are a solid investment for any property. At Tanks Direct, we offer a range of affordable treatment plants to suit any budget, but the premium Klargester BioDisc offers significant benefits with no noise, no odour and up to 7 years warranty*. 

Sewage treatment plants don’t require much upkeep, but it is important to keep them properly maintained and serviced. They will need emptying periodically, a process known as ‘desludging’, by a registered and licensed waste collection company. Treat your sewage treatment plant properly and it could last up to twenty years. If they are misused or not properly maintained, their lifespan will reduce significantly.

To keep your domestic sewage treatment plant working for as long as possible, pay attention to what you are flushing down the toilet and washing down the sink. Do not flush kitchen roll, food waste, nappies, baby wipes, grease, fats and oils or sanitary products down the drain and careful with the volume of cleaning agents and detergents you are using as these can sometimes overload the system. Areas with softer water will require weaker cleaning products than hard water areas. It’s also beneficial to get your sewage treatment plant regularly serviced, where a professional will come out and inspect your system and identify any potential issues before they get worse.

Although the two are often mistaken as the same thing, there are some distinct differences between the two. A sewage treatment plant creates a clean, environmentally friendly effluent which can be discharged directly to a watercourse. They typically require electricity to operate and need regular servicing and emptying. A septic tank only requires emptying once a year, doesn’t use any electricity, and doesn’t require servicing. However, they produce a very polluting waste product, which must be dispersed to a soak away and the septic pollutants go through further handling by the natural aerobic soil bacteria.

It is the level of the soil pipe entering the septic tank or treatment system.

If the flow from your system can not release without help, i.e. required to be uplifted you would need a pump to help with this.

Primary wastewater treatment

The primary treatment of wastewater removes material that will either float to the top or settle to the bottom. The wastewater is temporarily held in a settling tank, where the heavier solids sink to the bottom and lighter bits float to the surface. Once settled, these solids are held back while the rest of the liquid is moved through to the secondary phase of wastewater treatment.

Secondary wastewater treatment

A deeper and more rigorous secondary phase of wastewater treatment uses aerobic biological processes to substantially degrade the biological content of the waste, reducing common biodegradable contaminants down to safe levels. There are three ways to do this: biofiltration that uses filters to ensure that any additional sediment is removed from the wastewater, aeration which increases oxygen saturation by introducing air to wastewater and oxidation ponds that allow wastewater to pass through natural bodies of water for a set period before being retained for two to three weeks.

Tertiary wastewater treatment

Tertiary wastewater treatment aims to improve water quality to meet domestic and industrial standards. It involves removing pathogens to ensure water is safe for drinking

If you can’t connect to a public sewer, building regulations state you’ll need either a cesspool, septic tank or sewage treatment plant. At Tanks Direct, we offer a comprehensive choice from leading suppliers of waste water solutions such as Klargester, Rewatec, Harlequin or Clearwater.

Cesspools

A cesspool or cesspit is a sewage holding tank. The waste isn’t treated and there is no outlet (only vents to allow gas build-up to escape). Waste simply flows in to be stored and then, when the tank is full, a lorry tankers it away for disposal. A cesspool is a good option if the ground is unsuitable for waste to soak away or for sites that are close to drinking water supplies, as the waste is safely contained before being taken away.

Advantages of a cesspool:

• Cheap
• Low installation cost
• Low maintenance

Disadvantages of a cesspool:

• Sewage isn’t treated
• Requires regular emptying which can cost up to, £300 each time

Cesspools are banned in Scotland

Septic Tanks

Septic tanks can treat and discharge the liquid part of the sewage. Waste enters the first tank, where gravity separates the liquids from the solids. The liquid effluent flows out of the tank onto land, where it is cleaned as it percolates through the soil. Some sunken solids, or ‘sludge’, is broken down by natural bacteria, but the rest will need to be taken away by lorry. Septic tanks are suitable for single houses or small developments, but you’ll also need a drainage field that is porous enough to allow the waste to percolate through.

Advantages of a septic tank

• Relatively low installation cost
• Relatively low cost to run
• Only require emptying (or ‘desludging’) once or twice a year

Disadvantages of a septic tank

• Your ground must be porous enough to allow the liquid effluent to discharge
• New laws state septic tanks can no longer be discharged into a watercourse

Sewage Treatment Plants

Sewage treatment plants are suitable for everything - with small-scale, affordable domestic units available for single homes, to large-scale, commercial units available for large developments. They all work in the same way, creating an environment that allows helpful waste-degrading bacteria to flourish. Sewage treatment plants are the only option if you want to discharge your treated waste to a ditch or stream.

Advantages of a sewage treatment plants:

• Affordable
• Clean
• sewage treated to a higher standard so that it has minimal negative impact on the environment.

Disadvantages of a sewage treatment plants:

• Requires an electricity supply
• while the volume of solid matter is greatly reduced, it’ll still need pumping into a lorry for disposal.
• Require regular maintenance

 All commercial sewage treatment plants must adhere to general binding rules, a set of stringent regulations laid out by local authorities to meet both environmental, health and safety concerns. General binding rules stipulate several requirements when it comes to the placement of any commercial sewage treatment plant. It should be positioned a minimum distance away from buildings and water sources, especially if your business is in a protected area. The distance will depend on the size and capacity of your sewage treatment plant. It is strongly recommended that you seek professional advice on making your commercial sewage treatment plant compliant.

Depending on where you are in the UK, there are different rules relating to sewage treatment plants. You may need to apply for a Consent to Discharge licence from the Environment Agency, that says your wastewater is clean enough not to damage local wildlife. If you’re discharging less than 5,000 litres per day to surface water, you won’t need one.

You must apply for a permit:

• If you discharge more than 2,000 litres per day to the ground
• If you discharge to a well, borehole or other deep structure
• Where the tank is within an Environment Agency groundwater protection (SPZ) zone 1 (find out more at www.environment-agency.gov.uk).

If you are in any doubt whether you require a permit, check the government’s website here. 

It is highly recommended that you fully understand and adhere to all the regulations that will affect your installation and running of a sewage treatment plant. If you are the property owner where the tank is being installed, this is your sole responsibility, and you could be liable for heavy fines or repair costs if things are done incorrectly.

Sewage treatment plants work by separating wastewater from solid waste in a settlement chamber. Gravity causes the heavier, solid waste to sink to the bottom of the tank so that the wastewater can be treated before being released into the environment. The solid at the bottom of the tank, referred to as sludge, builds up reducing the available volume and space in the tank for the wastewater treatment process. Your tank will become less effective and will eventually fail causing problems.

For this reason, your sewage treatment tank will need emptying periodically ­– a process known as desludging. How often you de-sludge your tank will depend on the type of system you have as sludge build up varies between systems. We recommend you use a registered and licensed waste collection company who will be fully insured to handle the sludge. They will visit your site, remove the sludge from your sewage treatment plant tank, and take it away for disposal.

Although instructions are supplied with each of our products, installing a sewage treatment plant is no small feat and we do not recommend installing one yourself unless you are 100% confident you know what you’re doing. There are lots of health and safety issues to consider when excavating holes and if your sewage treatment plant is installed incorrectly you could find yourself in a nasty mess – both physically, financially, and legally.

Hiring a professional contractor to do the installation will give you complete peace of mind. Your sewage treatment plant will be installed safely, efficiently, and perhaps most importantly, it will be legally compliant. Be aware there are different rules relating to the installation of sewage treatment plants depending on whether you are based in England, Scotland, Wales, or Northern Ireland. You may need to apply for a Consent to Discharge from the Environment Agency – a licence that says that your wastewater is clean enough to release into the environment and not damage local wildlife.

It is strongly recommended that a suitably trained and qualified professional installs your sewage treatment plant. You could be faced with hefty repair costs, fines and even legal issues (that will be far greater than the cost of hiring a professional installer) if any part of your private sewage system is installed incorrectly. If you are confident you have the skills to do this yourself, you should have step-by-step instructions on how to do it from the manufacturer of your chosen tank, plus all the health and safety measures that should be taken. The following will give you a brief guide on what will be involved in the installation, but always ensure you adhere to the manufacturer’s guidance as some steps may vary.

Inspect tank for damage

Although our tanks will have been fully tested and checked before being dispatched to you, make sure to thoroughly inspect the tank for any damage caused during transportation as, once the tank is installed, we may not be able to accept your return.

Placing the tank

Ensure your hole is large enough for the both the tank and the recommended backfill. Prepare a base for the tank and carefully lower the tank into the hole, using the recommended lifting system, checking that the inlet and outlet orientation is correct. Ensure your tank is level and use the correct backfill, which might be concrete, gravel or sand, but check the manufacturer’s manual to see what they advise and follow their steps for adding the backfill.

Installing the inlet and outlet

Installing the inlet and the outlet should be straightforward, but it is always worth contacting a qualified plumber if you are unsure. Follow the manufacturer’s installation guide to connect the pipework. For easier maintenance access, some manufacturers advise the installation of an inspection chamber before and after the treatment to make life easier should any problems arise in the future.

Wire up the electrics

All electrical work should be conducted by a qualified electrician. The installation manual will detail what is required.

This is a very simplistic guide of what is required to install your sewage treatment plant. In addition to these steps, you may also need to install a soak away to complete your system.

A soakaway is a large hole dug into the ground, filled with stones, that manage the effluent and surface water by collecting, treating, and cleansing it, before letting it drain slowly back into the environment.

You do not necessarily need a soakaway for a sewage treatment plant ­– only for a septic tank. This is because the water released by a septic tank has only gone through one stage of treatment and is still hazardous to the environment. It is therefore important that water from a septic tank undergoes further treatment and cleansing in a soakaway before being safely released into the environment.

In a sewage treatment plant, the wastewater has already been through at least two stages of treatment and is therefore safe to be released directly back into the environment.

A soakaway, also known as an infiltration system, is a type of drainage system used to manage surface water runoff. It consists of a pit or trench filled with gravel, stone, or other porous materials that allow water to percolate through them and into the ground.

Soakaways are typically used in areas where the soil has good drainage characteristics, and they are often used to manage water from roof gutters, surface water drains, or other impermeable surfaces. The idea is that the water is directed into the soakaway, where it slowly percolates into the surrounding soil, reducing the amount of runoff and preventing flooding. 

It is advisable to get the buildup of sludge in your system cleared and the mechanical and electronic components serviced every six to twelve months.

A well-maintained sewage treatment plant should not give off any bad smells. They are designed to contain any naturally occurring odours that arise during the treatment process. If your sewage treatment plant has an unpleasant odour it is important to investigate the cause.

It could be that your tank is full and needs emptying. Check the levels of sludge in your tank and arrange for the tank to be emptied if necessary.

Clogged vents could also be the cause of odours. The vents in sewage treatment plants allow toxic and flammable methane gases present in the waste to escape. Check the vent isn’t clogged with waste, snow, ice, or an animal’s nest.

Bad smells can also be caused by contamination in your sewage treatment plant. Harsh chemicals, grease or fat will all interfere with the natural enzymes in your plant that work to break down the sewage. 

2015 saw the introduction of the General Binding Rules, designed to ensure that septic tanks and / or sewage treatment plants are installed and maintained to a required standard to minimise any adverse effects on the environment.

Since its introduction, further adaptations and additions have been made to the Rules and Government has recently announced the addition of two new rules for new discharges to take effect from 2nd October 2023.

The new rules are as follows:

Rule 22 – Use of combined outlets.

“A new discharge shall not use the same outlet as any other discharge if the combined volume of those discharges would exceed the volumetric general binding rules threshold for groundwater or surface water.”

Rule 23 – Discharge proximities.

“A new discharge shall not be made to a discharge point within 50 metres of any other exempt groundwater activity or water discharge activity.”

These new rules need to be considered when planning installation works in the latter part of 2023..

Commercial sewage treatment plants are large-scale waste removal systems for commercial properties that are either in a rural area or can’t be connected to the public sewage network. As they are entirely independent, they use a process that breaks down the waste into a clean product that can be directly discharged directly into the environment without harming the local habitat.

They function in the same way as domestic sewage treatment plants, but are designed to cope with a much higher volume of sewage. Commercial sewage treatment plants have a motor, powered by a generator or other electrical source, that circulates air within the system. Naturally occurring bacteria use this air to break down the wastewater in the system. This destroys the harmful substances in the waste, and, after several stages of treatment, the wastewater is clean enough to be pumped into the local environment.

Initially the waste goes through a pre-treatment stage, that removes large objects and solids. The waste is then pumped into a settlement zone, where liquids rise to the top and larger substances collect at the bottom thanks to their different densities. Bacteria starts to break down harmful substances and the sludge that forms at the foot of the tank is periodically removed. The remaining liquid is then ‘cleaned’ by a process known as ‘biological treatment’, where aerobic bacteria use the oxygen circulated by the motor to break down more harmful substances. Finally, the wastewater goes through a final round of cleansing to kill any remaining harmful substances that remain. This may involve chemicals to ensure the water is as clean as possible before it’s discharged. 

There are many reasons why you may need a commercial sewage treatment plant installed. If your business is in a rural location, you may be too far away to connect to the main public sewer system, or perhaps your access to the public sewers is blocked by a railway line. Commercial sewage treatment plants are also eco-friendly, so if your business is looking to become more eco-friendly, a commercial sewage system could be for you. The wastewater in a commercial sewage treatment plant is treated before being discharged, so there is no harm to the environment. They are also cost-effective. After the initial installation costs, commercial sewage treatment plants save money on bills paid to your local authority, making them an attractive long-term investment for many businesses. Commercial wastewater treatment plants can be set up quickly and easily. There are minimal odours and disruption to the running of a property and, if your system is properly maintained with regular servicing, your system will function for a long time.

Commercial sewage treatment plants function in much the same way as domestic sewage treatment plants but are designed to cope with a much higher volume of sewage. Commercial sewage treatment plants can service business and commercial properties where 50 or more people go to work. In contrast, domestic sewage treatment plants would usually only deal with household waste from up to four or five people.

You’ll want to choose a commercial sewage treatment system based on the size of the premises and the number of people using the facilities. But don’t go too small! It might save you money in the short term to buy a smaller system, but if you need to upgrade to a larger system in the future it will cost you.

It is important to keep any sewage treatment plant properly serviced and maintained, but with commercial sewage treatment plants professional maintenance may be required more often and require specialty maintenance to ensure everything is working as it should.

Sewage treatment plants are robust and effective and offer many benefits over some other methods of sewage treatment such as septic tanks and cesspits. But how much does a commercial sewage treatment plant cost? There are several costs to consider.

The sewage treatment plant

The price of your commercial sewage treatment plant will depend on a variety of factors. Get in touch and we will listen to understand your requirements and help you choose the best plant for your commercial premise.

Cost to install

The cost of installing your commercial sewage treatment plant will depend on whether you’re installing a brand new system or upgrading an existing one, as well as which plant you have chosen and where the plant is being installed. 

Annual service

You’ll need an annual service to ensure the ongoing performance of your commercial sewage treatment plant. The cost will depend on your equipment and location.

Emptying

Sewage treatment plants need to be periodically ‘de-sludged’.

Grease traps are a popular method of managing fats, oils and grease. At Tanks Direct we stock two types of grease traps for FOGS management — manual and automatic. Both do the same job of separating FOGS, solids and water within the tank, helping to prevent grease related issues. By slowing the flow of waste as it enters the grease trap and letting the wastewater cool, the elements naturally separate with solids sinking to the bottom, FOGS floating to the top and water remaining in the middle. What happens with each of these elements next is what differentiates a manual and automatic grease trap.

Manual grease traps are inexpensive and cheap to install. They simply contain and hold the FOGS until they are cleaned out. Automatic grease traps, also known as Automatic Grease Removal Units (or AGRUs), are more expensive than manual grease trap. However, automatic units systematically reheat and skim out the top layer of the tank where the FOGS sit, depositing it into a container where it can be disposed of easily. A separate filter catches any solid matter, which can be easily accessed and removed for disposal.

It is estimated that nearly half a million tonnes of grease and fat enter the UK sewerage system each year, causing blockages and damage to pipes and wastewater equipment. Grease builds up inside pipes as it sticks to pipe walls and, if it enters a natural water course, fats, oils, grease and starch (FOGS) can seriously damage the environment. This damage is extremely costly to local authorities so proper management of FOGS is heavily enforced. Failure to effectively manage buildup could lead to heavy fines or even closure of commercial businesses.

Grease traps collect and reduce the number of FOGS entering the main sewers, helping to prevent drain blockages, bad smells and pest infestations. They can be located above or below ground, inside or outside your property, but positioned within the wastewater drain that connects your sinks and appliances to the sewer system. Fats and oils are much less dense than water, so they float to the top so, when wastewater enters a grease trap, it slows the water flow down significantly, separating solids to the bottom layer, wastewater in the middle and FOGS at the top. Wastewater is then allowed to flow into the sewer, while the FOGS are trapped.

If you have high levels of fats and grease you should use a grease trap. This would be fitted before discharging to the sewer.

Damage to sewer systems from FOGS can be extremely costly to local authorities and so there is much legislation surrounding best practices and correct disposal of fats, oils and grease, particularly for commercial food premises. If your property is connected to the mains drainage system and you’re serving hot food to the public or your staff, Building Regulations (document H, section 2.21) state you should have a grease trap or another effective means of grease removal fitted.

If you operate a commercial kitchen, such as a café, a pub, a takeaway service, a restaurant, a bakery or a staff canteen, a grease trap could help you to effectively manage your FOGS.  

Water and oil don’t mix. Animal fats and vegetable oils are much less dense than water, so they float to the top. In a grease trap, waste that flows through is slowed down and allowed a settlement period where solid waste sinks to the bottom and FOGS float to the top. A trap on the outlet prevents FOGS flowing through, permitting only the cleaner middle layer of wastewater to flow into the sewer system. Your grease trap needs to be properly maintained to ensure its continued effectiveness with regular cleaning required every two to four weeks by a licensed contractor.

Grease traps ensure grease and other build-up does not enter the main sewer system. Whether they’re attached to sinks, dishwashers or any other wastewater appliance that produce FOG, grease traps all perform the same basic function, with perhaps slightly different approaches. The size of the grease trap you’ll need will depend on the flow rate of the wastewater running through it — the higher the flow rate, the bigger the grease trap. At Tanks Direct we stock a wide range of grease traps in different size options to suit every flow rate.

Sewage pumps are typically designed to operate intermittently rather than continuously. The duration a sewage pump can run continuously will vary. Smaller domestic sewage pumps are generally not built for continuous operation and are meant to pump wastewater as needed. Larger, industrial-grade pumps may have the capacity and durability to run continuously for extended periods, but even they may require periodic rest to prevent overheating and wear. Domestic sewage pumps are designed to handle typical household or small-scale sewage flows. If the pump has to handle a sudden surge or an unusually high volume of wastewater, it may not be designed for continuous operation under such conditions.

Continuous operation can lead to heat build-up in the pump's motor and components and overheating can cause damage or reduce the pump's lifespan. Pumps are usually designed with cooling mechanisms, but they may still need breaks to dissipate heat effectively. Regular maintenance can extend a pump's operational duration. Always consult the manufacturer's guidelines and specifications for your specific sewage pump. These guidelines often include recommended operating durations and intervals for rest. Following these recommendations is essential to ensure the pump's longevity and efficient operation.

A sewage pump station is a storage chamber incorporating a sewage pump which transfer either the foul or surface water to a local drain, manhole, sewer or soakaway pit.

A pumping station is used where a normal gravity system cannot be, either because there is insufficient fall over a distance, or the common collecting point is lower than the discharge point.

A sewage pump is a submerged pump that moves sewage solids from one point to another, usually from a septic tank or sewage treatment plant to a percolation area or soakaway pit which is a distance away of uphill. Alternatively, it can be used to pump into a gravity flow sewer mains.

The size of the pump required is down to the rise to main from the tank to the sewer, please call us for further help on this.

All Klargester pumping stations are suitable for pumping waste water effluent and sewage in accordance with BS 756-2. They are also designed in line with Building Regulations for Foul Drainage.

Your system size will depend on the type of waste you need to manage, your distance from the sewer and the difference in levels.

For expert advice, to help you select the correct system, please contact our specialist team. 

The key factors to size your system are as follows:

• Application: domestic, residential or commercial.
• Material application: sewage, effluent or surface water.
• Inlet depth (below ground level).
• Pumping distance and lift.
• Electrical supply.

The first cost to consider is for the sewage pump station itself. And this will vary greatly depending on the specific model you chose. Whether you need a single or double sewage pump station, you’ll find our prices at Tanks Direct are extremely competitive.

Then comes the cost of installation. If you are installing a pump for the first time in a space previously unprepared for installation, the cost will be higher than if you are replacing an existing pump. This is because all the additional preparation required has already been done. The location of your install could also have a bearing on the installation cost. If the site is awkward to get to or a difficult material to dig up, your costs will be higher.

You’ll also want to consider the ongoing maintenance costs of sewage pump stations. Regular servicing is essential to keep your equipment working as well as possible. Sewage pumping stations are subject to wear and tear and require regular servicing to operate effectively. Catching any issues early will minimise the risk of failure and help prevent costly repairs.

It is vitally important that your sewage pump station is regularly serviced and properly maintained. This will improve the day-to-day efficiency of your sewage treatment pump and help improve its lifespan. By inspecting the pump regularly, you can ensure all the components are working correctly

It is advisable to get your tank serviced once a year. Your tank will be emptied and cleaned, with any blockages removed. If any defects are detected during the service, it’s best to get faulty parts replaced as soon as possible. Failure to fix problems quickly can lead to major issues further down the line.

Sewage pumping stations can vary in noise levels, but they generally produce some degree of noise. The noise from a sewage pumping station primarily comes from the mechanical equipment used to pump wastewater, such as pumps, motors, and control systems. These machines can generate a humming, buzzing, or whirring sound, which can be audible depending on several factors. Larger pumps typically produce more noise than smaller ones. Modern stations often incorporate soundproofing materials and construction techniques to help minimise noise pollution. Most sewage pumping stations are designed to operate around the clock, but you may find that noise is more noticeable during quiet times, such as during the night, when ambient noise levels are lower.

Local regulations and community planning may dictate the noise levels allowed for sewage pumping stations. Authorities often set limits to ensure that these facilities do not become a significant source of noise pollution in residential areas.

Sewage pumping stations are designed to transport and pump wastewater, which can contain organic matter and sewage, leading to the potential for odours. However, the intensity and prevalence of these odours can vary widely. Well-designed systems incorporate features to minimise odours, such as properly sealed access points and ventilation systems that help disperse or filter out odorous gases. Regular maintenance of these systems, including cleaning and inspection, is crucial to ensure their effectiveness in controlling odours. Smaller domestic sewage pumping stations may generate fewer odours compared to larger, industrial-scale facilities. This is because the volume of wastewater and the concentration of organic matter are typically lower in residential systems. Warm and humid weather can intensify odours, making them more noticeable, and windy conditions can disperse odours and make them less perceptible. If the pumping station is located close to your home or living areas, you may be more likely to detect any odours, especially if there are issues with the station's design, maintenance, or ventilation.

Many local regulations and building codes require domestic sewage pumping stations to incorporate odour control measures to minimise any potential nuisances to nearby residents. These measures may include odour-neutralising chemicals or filters in the ventilation system.

Tanks are sized on the number of people using the system, you should allow 150 litres per person multiplied by the number of people using the property to calculate your 24hr storage capacity.

For commercial properties please contact us, and we can help size this for you. 

No the tanks are supplied without an inlet hole, this is usually drilled on site however we do supply the seal to make the hole water tight and should you require us to drill this for you at the factory, we can offer this also.
