Welcome to the Small Drinking Water Systems Web Page

The Department of Environmental Health (DEH) Small Drinking Water Systems program's purpose is to protect public health by helping water system owners and operators to provide pure and safe drinking water by preventing waterborne diseases, identifying risks of bacteriological, chemical and/or radiological contamination, conducting inspections, providing technical assistance, and working in partnership with the small drinking water systems in San Diego County.  The DEH has an agreement with the California Department of Public Health, Drinking Water Program for administration and enforcement of the Federal and State statutes and regulations for any water systems under 200 service connections.

Water System Classifications

  • A Community water system is a public water system that has 15 to 199 service connections used by year-long residents, or regularly serves at least 25 year-long residents.  Water systems that have 200 or more service connections used by year-long residents are regulated by the State of California Department of Public Health.  An example would be a community with residential homes served by a single water system.
  • A Non-Transient Non-Community water system is a public water system that is not a Community water system and regularly serves at least the same 25 persons during 6 months per year.  An example would be a school or workplace.
  • A Transient Non-Community water system is a Non-Community public water system that does not provide water to the same 25 persons during 6 months per year.  An example would be a campground or park.
  • A State Small Water System is a public water system that has 5 to 14 residential service connections, and does not regularly serve potable water to more than 25 individuals for more than 60 days out of the year.  An example would be a small residential community with 10 homes served by a single water supply.

Water Quality Monitoring

  • Bacteriological Monitoring Requirements:
    All small drinking water systems are required to test for the presence of total coliform bacteria on a regular basis per Federal and State Drinking Water Standards.  Community water systems and Non-Transient Non-Community water systems are required to test for bacteria on a monthly schedule.  Transient Non-Community and State Small water systems are required to test quarterly for the presence of total coliform bacteria.  All water quality testing is required to be analyzed by a State-certified laboratory.
  • Chemical Monitoring Requirements:
    In addition to bacteriological monitoring requirements, small drinking water systems are required to test for chemical constituents that are described in Title 22 California Code of Regulations. Primary Maximum Contaminant Levels (MCL's) address health concerns. Secondary MCL's are aesthetic standards that deal with taste and odor of the water, and are not health hazards. Contact the Small Drinking Water Systems Program at (858) 694-3113 for specific water quality testing for your small drinking water system.
