8400 Litre Underground water storage tank

UK Manufactured, Made from high strength PE, Rota-moulded-single piece, Concrete backfill not usually required

A "fitted' tank means the pipe-work (calmed inlet, filter and connectors) within the tank and spigot connections are pre-installed. The telescopic lid (aka neck & lid) are normally separated to avoid damage during transport. It''s a push fit job to get it to fit onto the tank neck. There is a rubber seal towards the bottom, which ensures a tight fit. The telescopic part is then pulled up to the required level and the backfill supports this extension. It is also good practice to run a bead of silicon around the inside, where the upper part slides over the lower part.

Designed for all standard in-tank filters. Polyethylene underground water harvesting tanks for use in industrial, commercial and domestic schemes. Suitable for Potable or non potable water. The tanks are manufactured in the UK and are available in a wide range of sizes. Made from virgin polymer. This range of UK-Manufactured underground water tanks has been scientifically designed to maximise strength whilst minimising their carbon footprint. The water tanks are suitable for any application that calls for underground storage of water or other non-corrosive liquids. Tanks are rotary moulded from high-quality polyethylene in the UK, minimising their transportation environmental impact. Tanks are designed so that they typically reduce the depth of dig by around 500mm compared to their conventional equivalents.
