RAINSAVER PE tanks systems are specially designed for rural rainwater harvesting. A vast majority of rural settlements in Malaysia is still without water supply and relies on alternative sources like rainwater for their daily needs.

RAINSAVER tanks are available in a range of sizes from 2000 litres up to as large as 25,000 litres and incorporates pre-filters like the First Flush Diverters or the Filtermax cyclone filter to remove sediments from the rainwater before stored in the tanks. The system collects rainwater from downpipes of building roofs, filters the water and stores it for use by villagers.
