Rain Water Harvesting & Water Recycling – Environmentally Friendly Renewable Energy

What is Rain Water Harvesting & Water Recycling?

Rainwater harvesting (RWH) is an incomplex technology which has been around for many years, before mains-water RWH was a common feature on most houses. Basically, RWH collects rainwater from runoff on roofs and impervious areas, this rainwater is then collected and utilised.

Uses:

• WC and urinal flushing
• Irrigation and landscape watering
• Garden watering
• Domestic laundry

Rainwater Harvesting - Gravity System

The Gravity System is ideal for domestic applications. It has a major advantage in that in the event of a power failure on site (or the rain stocks running dry) the system will automatically switch to mains supply to ensure a continuity of service.

Rainwater Harvesting (RWH) - The Direct System

The Direct System of Rainwater Harvesting and Water Recycling is also suitable for domestic applications. This system is used where it is impractical to have a header tank for example in homes that have converted attic spaces and no room for a header tank. Therefore filtered rainwater is pumped direct from the holding tank to the various appliances.

When the holding tank is running dry there is a small automatic charge of mains water into the storage tank to ensure the system never runs dry. The main advantage of this system is that rainwater is delivered to the appliances at mains pressure (3.5 bar).

Conclusion

A well designed and maintained RWH system can help considerably reduce the water demand for non-portable uses and help towards making a building or home sustainable and energy efficient.
