Rain water recycling
Rainwater harvesting is the collection of filtered rainwater from roofs and its storage, for re-use as and when required. Washing machines, toilets and gardens account for around half of domestic water usage. By using rainwater, savings can be made and the strain placed on over utilized mains supply can be reduced.Key advantages:
- Up to 50% of mains water can be replaced by stored water
- Deal water source for remote areas
- As part of a storm-water management scheme it reduces runoff and can control the flow-rate off site;
- Adds value to the property
According to the Chartered Institution of Water and Environmental Management, "Where there is negligible potential human contact the rainwater will usually only require coarse filtration to prevent leaf litter, debris and small animals entering the system."
Rainwater capture can also work when integrated with a drainage sewerage system.
