Strategy for State Small Water Systems, Domestic Wells and Other Self-Supplied Communities
Lack of Centralized Data
State small water systems, domestic wells and other self-supplied residences are permitted by counties and not regulated by the state. Because of this, the state has lacked data about the water quality or location of these systems and wells. Senate Bill 200, which established the Safe and Affordable Drinking Water Fund in 2019, requires counties work toward providing this data to the State Water Board. As a result, the State Water Board is beginning to develop a clearer picture about well locations and the scale of drinking water concerns for communities accessing water through these sources.
Risks of Contamination and Dry Wells
California’s 2021 Drinking Water Needs Assessment estimated that about half of state small water systems and nearly a third of domestic wells are at high risk of exceeding healthy drinking water standards, due to the likelihood of contaminants in groundwater.
Climate change and drought also contribute to unstable water supplies for these communities: for example, domestic wells and wells serving state small water systems tend to be shallower than those serving larger systems and are at greater risk of running dry. When these wells run dry or are damaged, it is difficult for communities to afford well drilling or repairs because they cannot distribute costs across a large population as with larger systems.
SAFER Drinking Water Response
The SAFER Drinking Water program’s response to these challenges has four key components: centralized state small water system and domestic well data, funding for counties to develop response programs, regional outreach and engagement, and a Point-of-Use/Point-of-Entry pilot.
The State Water Board is working with counties to collect water quality data on state small water systems and domestic wells. Once collected, the data (location, number of people served, water quality, etc.) will be available to the public online. Access to this data will enable better decision-making on local and regional levels.

The State Water Board will provide funding for counties that want to develop programs for domestic wells and state small water systems. Technical Assistance providers will support and train counties as they develop tailored programs based on the needs of local communities. These programs can offer solutions such as water sampling, consolidation, point-of-use and point-of-entry water treatment, well drilling, long-term hauled water, vended water, and bottled water.

The State Water Board will fund partners to implement regionalization processes in two regions of the state. Regionalization is a process where several local water systems and domestic well users in a region work together to identify solutions that can deliver safe, sustainable and affordable drinking water in the long term. Regionalization can include several wells or water systems being subsumed into one large water system, the creation of a new water system, the creation of a new governance structure, or managerial consolidation.
Funding Partners will identify, fund, and coordinate local groups and organizations to serve as Community Partners. Community Partners will provide expertise to develop community engagement strategies and will implement direct engagement with domestic well owners and state small water systems. In addition, Technical Assistance providers will offer guidance and technical expertise on elements of regionalization including assessing existing technical, managerial, and financial capacity of the region; understanding feasibility and water rate studies; and assessing long-term governance and funding options. The State Water Board plans to implement this two-region pilot in 2023. If successful, the approach may be implemented in other regions in the future.
Point-of-use (POU) devices treat water from a single outlet, faucet, or fixture, and point-of-entry (POE) devices treat water entering a house or building. These devices may be the only available solution for Californians with water quality issues in rural areas. The State Water Board is developing a pilot to better understand the challenges, needs, and opportunities in implementing POU/POE treatment as a sustainable approach. Currently, Water Boards staff are gathering input from stakeholders and writing a report about POU/POE approaches and challenges, and plan to begin a pilot in 2022.
Other Solutions for State Small Water Systems and Domestic Wells
The State Water Board funds various Technical Assistance providers that can directly assist with developing regionalization or consolidation efforts to connect state small water systems and domestic wells to public water systems.
