Document Description
The groundwater storage program would provide for 60,000 acre feet (af) of excess Metropolitan Water District of Southern California (Metropolitan) surface water to be delivered via existing connections and stored in the in the Orange County groundwater basin when available. When called by the Metropolitan during shortages of imported water, 20,000 af per year would be extracted from the Orange County groundwater basin and decrease by an equivalent amount the demand for Metropolitan firm deliveries; thereby, making additional Metropolitan firm deliveries available to the region. This operation would continue for up to three consecutive years. The term of the program would extend through year 2030. The program includes the participation of eight OCWD District groundwater producers. When the stored water would be extracted during a drought, the eight producers would pump it out and use it in their individual systems, and thus allow for the additional Metropolitan deliveries to the region.
