WaterGroup Pty Ltd has been commissioned to install a large scale rainwater harvesting system at Woolworths Wyong RDC. Woolworths is Australia’s largest food retailer and second largest private employer.
WaterGroup (WG) is working with Woolworths on its second large scale rainwater harvesting project, being executed as part of a nationwide RDC retrofit program that aims to achieve significant financial savings through water conservation in addition to the environmental and public relations benefits. The organisation is currently considering both rainwater harvesting and Managed Aquifer Recharge (MAR) for all of their RDCs around Australia.
Designed and installed by WG, the rainwater harvesting systems are some of the largest of their type in the world, providing Woolworths with significant financial savings as well as considerable environmental benefits.
Key highlights of WG’s rainwater installation for Woolworths include four rainwater storage tanks with a total combined capacity of 1,040kL; and collection area covering 22,000m², saving close to 90% of the potable water consumed in the cooling towers, or 13,000kL p.a., equating to almost $39,000 p.a.
Apart from reduced water consumption, benefits also include reduced sewer discharge, reduced chemical costs in the cooling towers, and reduced scaling of cooling towers due to the use of softer rainwater.
WaterGroup is an Australian leader in commercial rainwater harvesting solutions. Managing Director Guenter Hauber-Davidson has been involved in the design, construction and commissioning of a number of ground breaking rainwater capture, storage and reuse schemes.
