Title

San Jacinto Valley Enhanced Recharge and Recovery Program

Description

Eastern Municipal Water District is proposing to implement the San Jacinto Valley Water Banking - Enhanced Recharge and Recovery Program. The proposed program would allow EMWD to enhance current and future water supplies in the local groundwater basin by developing a groundwater water bank with total storage capacity of up to 90,000 af. Groundwater produced by the proposed program would be used within EMWD's service area water could also be made available to EMWD's sub agencies or other regional water agencies through an exchange, with no physical export of local supplies. The proposed program would include development of recharge facilities, extraction and monitoring wells, treatment/blending and disinfection facilities, potable and raw water transmission pipelines, well water collector pipelines, laterals from the raw water pipeline to the recharge sites, and other conveyance facilities and appurtenances required to support the proposed program. EMWD is proposing to implement the SJVWB ERRP in phases, Phase 1 project would be the first installment of the proposed program. EMWD is proposing to implement the San Jacinto Valley Water Valley Water Banking ERRP in phases; the San Jacinto Valley Water Banking ERRP - Phase 1 Project (Proposed Project) would be the first installment of the Proposed Program. The Proposed Project would implement groundwater recharge facilities at Mountain Avenue West to enable EMWD to recharge an average of approx. 7,000 to 30,000 AFY when recharge supplies are available, while relying on existing regional infrastructure to convey imported raw water to the proposed recharge basin. The proposed project also includes three new groundwater extraction wells, associated pipelines, monitoring wells, and treatment/blending and disinfection facilities to enable EMWD to initially extract and deliver up to 7,000 AFY to its existing potable water distribution system.
