Housing Association opts for a communal rainwater harvesting system

Intro

Freerain Ltd has recently supplied a communal rainwater harvesting system to Two Rivers Housing Association at their Turley Court site in Cinderford, near Gloucester.
The system supplies ten dwellings with collected rainwater from the roofs to supply WC flushing and an outside tap.

The System

13,000 litre underground storage tank
Freerain DUO204 control set
2 submersible pumps for duty/assist
Full mains top-up

It is estimated that the system will provide 265M3 of water per year, providing a financial saving and helping to reduce the overal environmental impact of the site.

The site also has an extenive range of other environmental measures, which enabled it to reach the Code for Sustainable Homes Level required.

This site is of particular interest as due to the design of the houses a header tank system for rainwater harvesting control system wasn't possible. Normally where dwellings share a collection tank, each dwelling uses its own secondary tank.
