Large scale commercial rainwater harvesting schemes can provide a significant contribution towards replacing valuable potable water. The Water Conservation Group can design innovative solutions, often with entirely gravity driven rainwater collection and distributed overflow diversion systems.

Our partner Tankworks has installed the key components in a number of major commercial rainwater harvesting systems.

In Sydney, Tankworks recently installed a ground breaking 660,000 L
rainwater harvesting scheme in a large car park for the irrigation of
extensive parks and gardens.

A football stadium is now irrigating its playing grounds with roof water
collected from 12 downpipes and stored in two 150,000 L tanks supplied and installed by Tankworks.

At a hospital Tankworks installed the interception works and supplied
120,000 L of tank storage to provide free rainwater to be used in the
hospital cooling towers.
