Rainstore Domestic System – Direct Feed ‘Mains Top Up’

From: £1,706.00

Rainwater harvesting is not a new concept. However, over the last century, its use has diminished with the availability of a clean, inexpensive and reliable water source through the mains supply. More recently, water demand has started to exceed supply, and localised flooding has become a major issue in many parts of the U.K.

Industry experts are now recognising the important role that Rainwater Harvesting (also known as rainwater recycling, and grey water recycling) has to play in alleviating both these problems.

With strategic water planners looking to reduce the amount of water consumption per head going forward. Solutions such as Rainwater Harvesting will play a critical role.



Here at Watersol, we have been working closely with a specialist manufacturer, having designed a supplied thousands of systems. Rainwater Harvesting is really the rather simple science of collecting and managing rainwater from roofs.

Considerations for fitting a rainwater collection system to an existing property

  • The external drainage from the roof needs to be modified to bring the water to a central point being the Rainstore tank.
  • Access for the Rainstore tank and excavation is required.
  • Internal plumbing is usually required to be separate out from the normal water supply. Reasons to install a Rainstore rainwater harvesting system
  • Rainwater harvesting (including rainwater recycling and some versions of grey water recycling) displaces a large proportion of the water that would otherwise be provided by the mains supply – thus reducing overall water supply costs. • It can provide an off-mains supply for remote areas.
  • It enhances a property and can completely satisfy the water requirements of the various levels of the Code for Sustainable Homes.
  • It can form part of an attenuation and rainwater management scheme, by reducing storm-water runoff and controlling the flow-rate off site.
