Water Quality Reports

These reports show the results of our monitoring for each calendar year. In the City of Fairfield, tap water has met all USEPA and State Drinking Water Health standards. The City of Fairfield has prepared these reports and delivered them as required by law. Included are details about where your water comes from, what it contains, and how it compares to State and Federal standards.

Urban Water Management Plan

As a water supplier, the City of Fairfield must update its Urban Water Management Plan every five years and submit it to the Department of Water Resources. The UWMP assesses the City's water infrastructure, supply and demand, and future projects over the next twenty years. The City's UWMP also contains the City's Water Shortage Contingency Plan, a plan that dictates how strict water conservation efforts must be in the face of a water supply shortage.
