Renergise Super Slim Wall Tank Rainwater Harvesting System 2014

Rain falling on the roof of a building is channeled via the existing gutters and down pipe to a filter which removes leaf litter and other debris before diverting the water into a storage tank. When a service demands water a pump is automatically activated and draws water from the tank. In the event that there is insufficient rainwater to meet demand a mains water valve is automatically opened to partly refill the tank.

Rainwater Harvesting Systems Additional Product Information

Our Rainwater Harvesting System collects rainwater for garden irrigation and toilet flushing. The slim profile modular tanks (each 220 litres) can be coupled together for extra capacity. A filter installed in the downpipe protects the quality of the water and a low pressure energy efficient pump is added to supply connected services.

The Renergise rainwater harvesting system is ideal for installing where space is limited and as a retrofit solution. A steel support frame makes this a safe and permanent fixture and all components are manufactured using high grade UV protected plastics for long life. A discreet and simple system to help homeowners minimize their use of mains water.
