Aquifer Storage and Recovery
General Waste Discharge Requirements for Aquifer Storage and Recovery Projects that Inject Drinking Water into Groundwater
The State Water Resources Control Board (State Water Board) adopted general waste discharge requirements for aquifer storage and recovery (ASR) projects that recharge groundwater with treated drinking water (General Order) on September 19, 2012. The purpose of the General Order is to streamline the permitting process and to ensure consistent requirements for these projects. ASR projects use injection wells to recharge groundwater aquifers during times when water is available. This water is recovered later from the aquifers when it is needed. * Aquifer Storage & Recovery Projects - State Board Resolution No. 2012-0046 * General Order for Aquifer Storage and Recovery Projects (WQ Order 2012-0010)
