Water is a valuable commodity and as the distance from the major city centres increases, the supply of good quality water becomes increasingly difficult. Many remote areas are not supplied with mains water. Rainwater can be used to supplement existing supplies. Without any loss of comfort, rainwater helps conserve valuable drinking water and reduce water bills. ecoRain is a sustainable rainwater harvesting system, which cleans and collects 95% of the annual rainwater run-off from roof catchment areas. Rainwater is stored in a belowground concrete tank and can be used for gardening, laundry, cleaning, and to flush toilets.
