How Does it Work?

Rainwater Recovery

The Working Principle

  1. Rainwater is captured via your existing guttering and drain-pipes.
  2. The rain water is then filtered.
  3. The rain water is stored in single, or multiple connected tanks, above or below ground.
  4. When needed, the rain water is pumped either directly to the points of demand, or to an internal holding tank.
  5. If the system runs low on rainwater the mains water back-up pump unit is activated and mains water supplies the systems. Equally if there is too much rainwater, it overflows to your existing soak away or drainage system.
  6. Once it rains again, the rainwater is collected and the system automatically changes back to the rainwater supply.

Key System components

  1. Filter Units – remove silt and leaves.
  2. Storage tanks – these can be above or below ground and come in a variety of shapes and sizes and are made of a variety of different materials i.e. plastic, GRP, or even concrete.
  3. Pumps & Controls – manage demand i.e. pump water to your point of use and controls the level of mains supply to your system.

Key Considerations

  1.  Your existing guttering and downpipes from your roof may need to be modified to bring the water to a central point.
  2. If you prefer the storage tanks to be underground then excavation work will be required.
  3. Some internal plumbing is usually required to separate the drinking and bathing water from the non-drinking rain water for your toilets, washing machine & outside taps.
