The Municipal Utilities Department (MUD) provides water service to residents and businesses in the North and South Stockton areas.
Approximately 25% of the City’s water supply originates from groundwater wells with the remaining water supply from treated surface water supplied by the Stockton East Water District (SEWD). Learn more about SEWD in External Links below.
The Delta Water Supply Project has been completed. MUD will reduce the amount of water received from SEWD and reduce the amount of groundwater pumped each year. This reduction improves the City’s water supply reliability and protects its groundwater resources. The new facility can supply up to 30 million gallons per day (MGD) of drinking water to Stockton residents.
A daily report of water pumped from the Delta and a 15-day running average is available.
The City recently completed construction of its new 30MGD drinking water treatment plant and intake and pump station facility. The Delta Water Supply Treatment Plant provides a new supplemental, high quality water supply for the Stockton Metro area.
The finished project:

The Delta Water Supply Project Water Treatment Plant was awarded a Gold LEED, an award established by the U.S. Green Building Council and verified by the Green Building Certification Institute. The Plant achieved Gold LEED certification for energy use, lighting, water and material use, as well as incorporating other sustainable strategies.

Urban Water Management Plans (UWMPs) are prepared by California's urban water suppliers to 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 5 years and submit to the Department of Water Resources.
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 non-potable water would extend the City’s water resources, address groundwater overdraft, and re-use water that would otherwise be disposed.
The City’s comprehensive Water Conservation Program includes:
Currently, MUD's residential and business customers pay a monthly water rate based on both:
In 2009, the Stockton City Council approved a four-year water rate increase as defined in the 2009 Water Rate and Financing Study.

The United States Environmental Protection Agency safeguards the quality of our water supply under the U.S. Safe Drinking Water Act of 1974. In many cases, California's standards are more stringent than federal standards.
