Urban Water Management Plan


Hetch Hetchy Reservoir

Water planning is an essential function of water suppliers, particularly during extended periods of drought and diminished supplies. Since the early 1980s, the State of California has required water purveyors that provide 3,000 or more acre feet of water per year, or have 3,000 or more service connections, to prepare an Urban Water Management Plan (UWMP) every five years, in years ending in five and zero.

UWMPs provide a framework for long term water resource planning at the local level to ensure adequate water supplies to meet current and future demands.

More specifically, the UWMP:

  • Quantifies current and future water demands over a 25-year planning horizon
  • Assesses the reliability of water supplies in normal and dry years
  • Describes water shortage contingency plans
  • Describes current and planned demand management efforts
  • Documents the progress towards meeting target water use reductions as required in the Water Conservation Bill of 2009

The UWMP also includes a Water Shortage Contingency Plan (WSCP), which will guide the City’s response to water supply shortage conditions, including strategies to address six levels of water supply shortage conditions.

The 2020 UWMP and the 2020 WSCP were adopted by the Hayward City Council on July 20, 2021. They can be accessed electronically using the link below.
