Domestic_rainwater_harvestingDomestic Rainwater Harvesting Systems utilise rainwater from the roof to flush toilets and wash clothes, as well as watering the garden and washing the car.

You can save up to 50% of mains water on average and the water collected is extremely clean.

Water is stored in an underground tank, which keeps it cool and dark, preserving water quality. Leaves are filtered out before storage. A pump inside the tank pumps the wither directly to the toilets or up to a header tank. These are the two main principles of rainwater harvesting. a mains back up is provided, either by topping up the tank a little when it is dry, or directly to the headertank.

Our rainwater harvesting systems for domestic toilets use a fine particle filter to ensure water quality is as best as it can be and we always only use a main brand pump from the leading manufacturer DAB

Four Stages of filtration – For the ultimate in water quality

  1. In tank filtration:  built-in filter within the tank to stop leaves entering the tank.
  2. Calming inlet: any fine particles will settle to the bottom and due to the calming inlet pipe fitted to our system, they won’t be disturbed. It can take 10-15 years for sediment to build up to a point where it may need to be removed.
  3. Pump Particle filter: with a mesh size of 0.5mm to ensure no sediment gets through the pump.
  4. HydraRainmaster Trio: This filter is there for protection. By the time the water gets into the house it should have no fine particles. However, this added protection illuminates the risk by filtering to 0.01mm. We also include the carbon filter element into this filter (carbon is what is in a Britta filter) to ensure that water is crystal clean.
