Water Facts: Easy Ways to Learn More about City of Stockton Water

 

Water Supplies

Approximately 25% of the City’s water supply originates from groundwater wells with remaining water supply from treated surface water supplied by the Stockton East Water District (SEWD). Learn more about SEWD in External Links below.

  • With the completion of the Delta Water Supply Project, MUD will reduce the amount of water received from SEWD and amount of groundwater pumped each year – improving the City’s water supply reliability and protecting its groundwater resources. 
  • Read the daily report of water pumped from the Delta and a 15-day running average. 

 

Delta Water Treatment Plant

The Delta Water Treatment Plant provides a new supplemental, high-quality water supply for the Stockton Metro area – up to 30 million gallons per day (MGD). The finished project:

  • replaces declining surface water sources,
  • protects groundwater supplies, and
  • provides for current and future water needs.

Please Contact Us for public tours. For security reasons, tours are by appointment only. 

The Delta Water Treatment Plant was awarded a Gold LEED for energy use, lighting, water and material use, and other sustainable strategies. 

 

Water Resources Planning

Urban Water Management Plans support long-term resource planning and ensure adequate water supplies are available for current and future water demands. Every urban water supplier that provides over 3,000 acre-feet of water annually or serves more than 3,000 or more connections is required to assess the reliability of its water sources.

This assessment is over a 20-year planning horizon considering normal, dry and multiple dry years. The Urban Water Management Planning Act requires the City to prepare this plan every five years and submit to the Department of Water Resources. 

 

Recycled Water

The 2010 Joint Water Recycling Facilities Planning Study is an effort between the City of Stockton and the City of Lodi to consider the feasibility of using Lodi’s treated wastewater as a recycled water source for the North Stockton area. The use of nonpotable water would extend the City’s water resources, address groundwater overdraft, and reuse water that would otherwise be disposed of. 

 

Water Conservation

The City’s comprehensive Water Conservation Program includes:

  • long-term planning,
  • incentives and water-saving tips,
  • residential, business and landscape conservation,
  • school programs, and
  • programs designed for resident and business customers.

 

Water Quality

The U.S. Environmental Protection Agency safeguards the water quality under the U.S. Safe Drinking Water Act of 1974. Many California standards are more stringent than federal standards. 

Your water supply meets all federal and state drinking water standards.
