Case Study

Wynn Vale Dam Stormwater Harvesting

Source: Amiad Water Systems

Picturesque Wynn Vale Dam in Adelaide is the site for the City of Tea Tree Gully (CTTG) Council's innovative stormwater harvesting and reuse initiative. This Waterproofing Northern Adelaide (WNA) project is designed to treat 400 Mega litres of stormwater that will be extracted from the dam every winter to go into aquifer storage.During the warmer months, the water will be recovered by extracting it from the aquifer for irrigation and dual reticulation purposes.

Amiad Australia was involved in this project since 2007 and has trailed a tested a number of different technologies (exclusive to Amiad Australia) to determine the best water treatment process. Amiad Australia was contracted to install a stormwater treatment plant to increase the quality of the water collected in the dam to the requirements for Aquifer Storage and Recovery (ASR) as outlined in the EPA license held by CTTG.
