Product Description

Below Ground Water Tank - 10000 Litres (approx 2200 Gallons)

This robust water storage tank, manufactured in virgin polyethylene plastic provides 10,000 litres (2200 Gallons approx) of capacity.  Suitable for rainwater storage (and water storage for other non-potable uses). These underground water tanks are generally used to store harvested rainwater, however they can also be used to store water pumped from other sources, for example, wells and springs. 

The high-strength, ribbed design allows for environmentally friendly pea-gravel backfills and eliminates the need for any concrete to be used in most situations. Some installations may require further advice and an alternative installation method.

The tank features large 600mm access which allows access for inspection and maintenance and for other components like pumps and filters to be installed. See our Rainwater Pump Kits and range of rainwater filters for below ground water storage to build a complete below ground rainwater harvesting system.

This below ground water storage tank is moulded using a rotational moulding process which produces a stress-free product.  The Polymer used includes additives which make it resistant to harmful UV rays from the sun and with correct installation and general on-going care, these products have a long lifetime ahead of them with very little or no maintenance required.  They are extremely robust and very resilient and are able to withstand the most extreme conditions from the elements.
