Safe Drinking Water Program

Our mission is “to protect and promote the health, the environment and the well being of Southern Nevada residents and visitors and manage public health hazards in the environment.”

Since 1977 the health district’s Safe Drinking Water Program (SDWP), has contracted with the Nevada Department of Environmental Protection’s Bureau of Safe Drinking Water (BSDW), to oversee all of Clark County’s ground-water systems not in the direct influence of surface water (approximately 97 public water systems).

The BSDW is the U.S. Environmental Protection Agency (EPA) designated primacy agency responsible for the implementation of the federal Safe Drinking Water Act. We assist the BSDW in ensuring that all allocated water systems meet the national Safe Drinking Water standards (40 CFR 141), the Nevada Revised Statutes (NRS), Chapter 445A- Water Controls, and the Nevada Administrative Code (NAC) 445A.450 to 445A.6731, inclusive. Our efforts involve, but are not limited to,

  • Conducting sanitary surveys of water systems.
  • Conducting site visits to assess conditions that can attribute to total coliform positive sampling events.
  • Reviewing sampling plans.
  • Educating operators of water systems.
  • Managing lab results for compliance with to NAC 445A.454 and 445A.455.

Sanitary Survey Information

Public Water Systems Resources

Information About Private Wells


  1. Annually survey at least a third of all community and non-community water systems in Clark County.
  2. Monitor the operation of all non-surface water impact ground-water systems in Clark County.
  3. Assist small public water systems with compliance issues.
  4. Assess each water system’s compliance with monitoring primary and secondary water quality standards
  5. Provide educational resources to water system purveyors and their operators to improve compliance and best management practices for the betterment of potable water standards.
  6. Investigate consumer complaints related to permitted and un-permitted water systems.
  7. Follow-up on water systems listed as having significant deficiencies and delinquent monitoring violations.
  8. Ensure cross-connections within water systems do not exist that would jeopardize human and environmental health.


  1. Record results of all sanitary surveys using the Safe Water Information Field Tool (SWIFT).
  2. Mail sanitary survey reports to public water systems with significant deficiencies within 30 days of the site visit. All other reports should be completed within 45 days of the site visit.
  3. Schedule with the BSDW personnel a minimum of three joint sanitary surveys annually.
  4. Enter all monitoring results and run compliance status for all public water systems for coliform monitoring, at least monthly, and for all other constituents at least quarterly.
  5. Provide SWIFT migration files to the BSDW quarterly.
  6. Work cooperatively with the BSDW to implement new EPA rules that have not been adopted at the state level.
  7. Update actions taken during the previous quarter to address public water systems on the EPA Enforcement Targeting Tool with greater than 10 points.
  8. Maintain forms and applications for the Drinking Water State Revolving Fund and Grant Program.
  9. Respond to all types of technical assistance requests from water system owners/operators in a timely manner.

Timeline of Measurable Outcomes

  1. The SDWP will electronically track and manage annual assigned work load.
  2. Sufficient time will be allocated to ensure that sanitary surveys and follow-ups are thorough and provide operator education. The average small water system survey consists of five hours of pre-on-site preparation, two hours on-site, and five hours of follow-up work. However, some systems (e.g. water districts) will require a minimum of two days on-site.
  3. The SDWP will submit quarterly reports to the BSDW, and conduct monthly meetings with the SDWP Manager and BSDW Supervisor in an effort to distribute knowledge, and monitor and manage workload.
  4. Water systems with total coliform positives and deficiencies will be given priority for sanitary surveys and site visits.
  5. Administrative staff will process all total coliform negative results, and the SDWP will enter all total coliform positive results in the Safe Drinking Water Information System (SDWIS) database.
  6. Training from the BSDW will address how chemical monitoring results will be entered into the SDWIS.
