The Metropolitan Water District of Southern California approved a Local Resources Program agreement with the Eastern Municipal Water District for the Perris II Brackish Groundwater Desalter which will provide EMWD with a subsidy of $305 per acre-foot. The MWD board action Nov. 8 will provide EMWD with the $305 per acre-foot subsidy for up to 5,500 acre-feet annually over a period of 25 years. If the maximum amount of groundwater is recovered for beneficial use MWD would subsidize $41.9 million for the 137,500 acre-feet.
