Aldinga Wastewater Storage and Recovery
SA Water and the Willunga Basin Water Company are operating an Aquifer Storage and Recovery (ASR) Scheme at the Aldinga wastewater treatment plant. The scheme involves recycled water being stored in the aquifer (30-70m beneath the surface) in winter when irrigation demand is low. It is then retrieved and used by irrigators during the summer months.
The recycled water that is stored in the aquifer is sourced from the Christies Beach wastewater treatment plant at a quality suitable for the irrigation of vineyards. The Department of Health and the Environmental Protection Agency (EPA) have granted approval for this scheme, and set conditions for storing and supplying recycled water.
This project has enabled SA Water to increase the use of recycled water from the Christies Beach wastewater treatment plant, reducing the amount discharged to the Gulf St Vincent. The project also benefits the River Murray by replacing potable supplies currently being used for irrigation.
