WaterPipes at Delta Water Treatment Plant

The Municipal Utilities Department (MUD) is one of the water service providers to the Stockton area, serving more than 48,000 connections to residences and businesses in North and South Stockton.

 

Facts

In 2012, the City completed the Delta Water Treatment Plant (DWTP) providing a supplemental, high-quality water supply for the Stockton Metro area -- up to 30 million gallons per day.

 

The DWTP was awarded a Gold LEED for energy use, lighting, water, and material use, and other sustainable strategies. The water treatment plant also:

  • Replaces declining surface water sources,
  • Protects groundwater supplies, and
  • Provides for current and future water needs.

 

Water Master Plan Update

The 2021 Water Master Plan Update (WMPU) adopted in February 2021, updates the existing 2008 Water Master Plan in accordance with the Envision Stockton 2040 General Plan Update. The WMPU includes analysis of the City Water Utility’s existing system, projected water demand based on the 2040 General Plan, water supply, calibration of the City’s water distribution system’s hydraulic model, identification of infrastructure needs, and development of short-and-long-term Capital Improvement Program (CIP) with cost estimates for future improvements.

 

Sources

The City treats and distributes potable water from these sources:

  • Surface water diverted from the Sacramento San Joaquin Delta
  • Surface water from the Mokelumne River purchased from Woodbridge Irrigation District
  • Local groundwater from wells owned and operated by the City
  • Treated water purchased from the Stockton East Water District (SEWD), imported from the New Melones (Stanislaus River) and New Hogan (Calaveras River) Reservoirs
