The Ecosure 10,000 litre Rainwater Harvesting Tank is a rainwater harvesting system designed to collect water for Commercial applications. The system consists of an industrial strength polyethylene tank, complete with filter and calmed inlet. It offers great savings on mains water consumption and can also act as part of a water attenuation system.

Why choose an Ecosure Rainwater Harvesting System?

We are proud to be part of the Made in Britain campaign. Ecosure Rainwater Harvesting Tanks are designed and manufactured at our factory near Cambridge. Made with ease of installation in mind, they combine real quality with excellent value for money. All of our tanks are manufactured from the highest quality tank-grade virgin MDPE. They are rotationally moulded using a one piece mould and come with a 10 year guarantee against manufacturing defects. The integrated lifting eyes allow for easy manoeuvring and all our tanks are compatible with up to 6" pipe fittings.

The VF1 Combi is suitable for roof areas up to 450m2 and can be installed inside or above the tank. Clean water is directed out of the bottom of the filter, making installation easy. Dirt and debris are washed sideways and can be directed to a soakaway or sewer using 110mm pipe. The Twin Filter is suitable for larger roof areas up to 800m². Due to its two step cleaning system, it has a high level of filtering efficiency, independent of flow rate. The steep inclination of the filter cartridge means dirt is continuously cleaned away into the sewer.

Mains water back up

Fitting a Partfill Valve will ensure that you never run out of water when there is little or no rainfall. The Partfill Valve is a high flow valve which will automatically use mains water to maintain a set level of water in your tank.

External Tap System

This system pumps water from your rainwater storage tank to a wall mounted tap. It is ideal if you need a wash down area. Use it for cleaning equipment, feeding a jet wash, etc. The HydroForce Series 3 is a British made, electronically-controlled, pressure-sensitive, centrifugal roto-dynamic pump with no reciprocating parts. Max head (nominal) 35 metres, pump pressure (nominal) at outlet 3.5 bar, max suction 3 metres. It comes with two-year return-to-base guarantee.
