The Underground Water Storage Tanks  are suitable for both domestic and commercial applications, available in both non-potable or potable versions.


The tanks are mainly used for rainwater harvesting applications, but can also be used for water attenuation and storage of water from other sources such as wells and springs.


These robust water storage tanks are manufactured in the UK and are moulded from Polyethylene using a rotational moulding process which produces a stress-free product.  Furthermore, there are many design features that make these tanks stand out.  The high strength ribbed design allows for environmentally friendly pea-gravel back-fills which as a result eliminates the need for the high costs and difficulties of encasing a tank in concrete.  The shallow-dig depth also makes them easier to install and maintain, as well as being ideal for areas with a high water table (certain installations may require further advice and an alternative installation method).  The curved design allows more efficiency when using submersible pumps as it enables all the water, even from the bottom of the tank to be pumped out.


This range of tanks are amongst the most dependable in the market place and the industry leading warranty offers extra peace of mind. (See details below)
