Arcata 2015 Urban Water Management Plan


The City of Arcata’s Urban Water Management Plan (UWMP) was developed to document our water supplies, demands, and conservation efforts.  The UWMP is intended to be a long-term planning tool to ensure water supply reliability for our customers, especially during periods of drought or water shortage.  The UWMP is updated and adopted every five years in accordance with California Water Code.
