Customer Agencies

Upper District purchases water from the Metropolitan Water District of Southern California and provides water on a wholesale basis for sale to 29 customer agencies in the San Gabriel Valley.

Our customer agencies include municipal water departments, investor-owned water companies and land-owner held mutual water companies that in turn provide the water at retail water rates to their residential, commercial and industrial customers.

Upper District also works with these 29 member agencies to provide water conservation and education programs, and develop stormwater capture projects.

State Board Mandatory Water Conservation Regulations

em_cons_reg_waterdropOn May 5, 2015 the CA State Water Resources Control Board (SWRCB) adopted an emergency regulation requiring an immediate 25% reduction in overall potable urban water use statewide in accordance with Gov. Jerry Brown’s Executive Order issued on April 1, 2015.  To reduce water use by 25% statewide, the regulation adopted by the State Board  places each urban water supplier into one of eight tiers which are assigned a conservation standard, ranging between 4% and 36%.  Local water agencies will determine the most cost effective and locally appropriate way to achieve their standard.
