Customer Agencies

Upper District purchases water from the Metropolitan Water District of Southern California and provides water on a wholesale basis for sale to 27 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 27 member agencies to provide water conservation and education programs, and develop stormwater capture projects.
