The Municipal Utilities Department (MUD) provides water service to residents and businesses in the North and South Stockton areas.
The City operates the water utility under a permit issued by the State Water Resources Control Board, Division of Drinking Water.
The City of Stockton previously mailed a notice of a Public Hearing for May 24, 2016, at 5:30 p.m. to consider the adoption of rate adjustments for its water service. Since that notice, the City has achieved additional costs savings by reducing its debt obligations for the water utility. As a result, the City has been able to reduce the proposed rate adjustments. The Public Hearing has been rescheduled to consider the updated rate adjustments.
The City of Stockton invites the public to attend the rescheduled Public Hearing to consider adoption of a 5-year schedule of water rates on:

Three easy ways to learn more about our water:
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.
Daily report of water pumped from the Delta and a 15-day running average is available.
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:

The Delta Water Treatment Plant was awarded a Gold LEED, 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:
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.
The City's water system recently violated a drinking water standard. Although this is not an emergency, as our customers, you have a right to know what happened, what you should do, and what we are doing to correct this situation. The City issued a notice that only applies to City of Stockton Water Utility customers who live in North Stockton.
MUD regularly monitors the City Water System for drinking water contaminants. On October 14, 2015, testing results showed two locations where the water system exceeded the maximum contaminant level of 80 parts per billion for Total Trihalomethane (TTHM). This exceedance was calculated based on the Locational Running Annual Average (LRAA) collected quarterly at sampling locations over the past 12 months. The LRAA for TTHM collected at two sample locations west of Interstate 5 in northwest Stockton ranged from two to four parts per billion higher than the established standard.
Residents do not need to use an alternative water supply, such as bottled water. This is not an immediate risk. TTHMs are organic chemicals that form when disinfectants react with naturally-occurring organic matter in surface water supplies. With increased conservation this year, due to the drought, water may be holding in the City's storage and distribution system longer, giving the TTHM more time to form.
Once the TTHM levels were determined, the City took immediate action by changing water sources, modifying the treatment process, and conducting system-wide flushing. MUD anticipates resolving the problem within three months.
