Rainwater Harvesting

Rainwater harvesting is the collection and storage of rainwater, instead of letting it run off into the ground. There are various rainwater harvesting methods available but generally rainwater is collected from roof-like surfaces and redirected to a rainwater harvesting tank, either above the ground or below.
Rainwater harvesting has traditionally been used for watering the garden but, thanks to new technology, a rainwater harvesting system can be plumbed into your home’s existing pipework so that you can harvest rainwater to flush your toilets, wash your clothes and many other non-human consumption related applications. According to the Rainwater Harvesting Association, you could reduce your water consumption by as much as 40% which will lower your water bills if you’re on a water meter.
Harvesting water from the rain makes good ecological, as well as economic sense. As our population continues to grow, so does the demand on mains water. Both families and businesses are looking for ways to reduce their environmental impact and rainwater harvesting systems are increasingly in demand.
We stock a wider range of rainwater harvesting systems, including commercial and domestic rainwater collection systems, systems that sit both above the ground and below the ground, rainwater harvesting kits, and rainwater tank accessories.
Find out more about using rainwater in the home and rainwater harvesting methods in our guide here. If you are unable to find what you are looking for in our rainwater storage range, please call us on 01643 703358.
