Rainharvesting Systems Ltd. in partnership with specialist installers Natural Power UK, devised and supplied the rainwater harvesting scheme for this social housing development.
The inclusion of rainwater harvesting enabled the client to achieve Level 4 of the Code for Sustainable Homes.
The system is designed around a single 10,000-litre tank supplying all 7 properties on the site. The harvested water is pumped to a small individual header tank in each dwelling.
The header tanks are designed to take water from the rainwater store as long as it is available, but to automatically revert to running from mains water when the main tank runs low, or in the event of power failure. The central controls for the system are securely housed within an external, insulated and lockable enclosure and run from the landlords’ power supply.
Browning’s Close is just one of many social housing projects we have been involved with.
