Here are the options...

Our Home System

This ingenious system uses cutting-edge pump technology to run alongside the mains water supply into your house, switching automatically as required between stored rainwater and mains water. Thanks to a very efficient, self-cleaning filter it has a water yield of more than 95%.

When the holding tank is running dry, there is a small automatic charge of mains water into a separate storage tank. This ensures that the system will never run dry, but also that there is no mains water used unnecessarily once the main tank is filled with rainwater again.


  • Dry, wall-mounted pump control unit with automatic mains switch
  • Pump delivers rainwater to appliances at mains pressure
  • Equal wall thickness throughout the tank makes it stable, strong and reliable
  • Tank is made from Duralen, a recyclable material
  • Lightweight tank can be supplied in two halves for restricted sites

Save upto 95% of the water you use and save money with rainwater harvesters...

enjoy the rain and save money...

Water has never been in higher demand - climate change, a growing population and shifting user habits mean we are consuming more of it than ever. The UK’s climate leads many people to think we will always have an abundant supply of water, yet often, we either have an over-supply or a drought. Harvesting rainwater can help in both these situations, as well as making sensible use of a free resource.
