Scientists at CSIRO are piloting the use of aquifers to store and recover urban stormwater and treated sewage effluent. The reclaimed water is good enough to irrigate urban landscapes or crops and the stormwater vitalises brackish aquifers by reducing their salt content. Aquifers can be recharged in wet periods and the water recovered in dry periods. This is usually cheaper than storing the water in dams. Clogging of injection wells and monitoring aquifers so that low-quality water can be managed sustainably have been addressed. Pilot projects have taken place in Adelaide, supported by the South Australian Department for Water Resources. Future projects will be integrated with urban water management.
