Our 8400 Litres Underground Water Tank complies with EU and UK regulations and is manufactured in the UK from high strength polyethylene. Moulded using a rotational moulding process, this tank is mainly used for storing harvested rainwater; however, it can also be used for storing water from other sources such as springs and wells.
Designed with strength in mind, it is shorter in height compared to other tanks on the market today. This means that a shallower hole is needed to accommodate the tank, and this can be by as much as 500mm less.

The ribbed design provides added strength and efficiency, while also allowing for an environmentally friendly pea-gravel backfill, eliminating the need for a time consuming and high cost concrete base and backfill to be used. The curved element of the design also enables all water, even from the bottom of the tank to be pumped out.
These tanks are amongst the most dependable on the market and as such are supplied with an industry leading 10 year warranty. With the correct installation and general on-going care, these tanks have a long lifetime ahead of them with very little or no maintenance required.
Optional telescopic neck, lid and calmed inlet drainage pack
As standard, this tank is supplied as a plain tank with no accessories or fittings. The optional telescopic neck and lid push fits into the neck of the tank and a rubber seal located towards the bottom ensures a tight fit. The telescopic part of the neck can be extended by up to 300mm and can be tilted in any direction by up to 5 degrees.
The calmed inlet drainage pack includes a rainwater filter and is designed to filter incoming rainwater and helps prevent it from becoming stained and odorous. The calmed inlet slows down the speed the water enters the tank and introduces the water into the lower part of the tank. As a result of this controlled entry, the water does not disturb any sediment at the base and replenishes the supply of oxygenated water throughout the tank, not solely at the top. This keeps the water inside the tank fresher for longer.
