The Project

Waterproofing the East involved the design and construction of an Aquifer Storage and Recovery (ASR) Scheme to harvest, treat, store and distribute recycled stormwater for irrigation purposes across the eastern region of Adelaide. The Client for the Project is ERA Water, a regional subsidiary formed between three Councils; Town of Walkerville, City of Norwood Payneham and St Peters, and City of Burnside. Stormwater is harvested from Third and Fourth Creeks and treated at one of two treatment sites; the Felixstow Reserve wetlands and biofilters, and the Hamilton Park Reserve biofilters and UV disinfection system. Treated water is injected into a fractured rock aquifer for storage and is extracted as required for irrigation of parks and reserves.

Technical Excellence

WGA superintended the three main construction packages; pipeline installation, mechanical and electrical installations, and civil works. Over 40km of pipeline, bores and pump stations, a wetland and biofilters have been constructed.

Client Focus

The scheme aims to supply up to 450ML per annum of recycled water for public open space irrigation. This irrigation water supply will reduce reliance on the SA Water mains water supply and, therefore, the demand on the River Murray and provide improved liveability amenities.
