For the purposes of our Department, Clean Water means stormwater (the water that is the result of rainfall or snow melt). The Clean Water Division provides management and coordination services related to all things stormwater, including drains in the roadways, stormwater facilities in neighborhoods, reducing pollution at businesses and educating the public about their watersheds and local streams. Drinking water is regulated by Clark County Public Health, and more information can be found on the department's webpage.
Neighborhood stormwater facilities may be private (responsibility of the homeowner's association) or public (maintained by the county or local jurisdiction). Call the number or submit an on-line form on our webpage to let us know the location of the facility. We can let you know who owns the facility. If it is privately maintained, we can assist the HOA with operation and maintenance standards for the specific type of facility. If it is publicly owned, we can work with the appropriate staff to discuss maintenance issues or concerns.
If you see someone dumping materials (other than clean stormwater) down a storm drain you can contact our specialist at the phone number on this webpage. You can also contact us if you see a spill or discharge (i.e. leaking dumpster or storage container) that is entering a storm drain. You may also use this on-line form. If the spill looks like it could pose a risk to human or environmental health, call 911 immediately.

Clark County updated the Clark County Stormwater Manual in 2021 and became effective in July 2021. The manual provides all of the technical details for you to plan, design, permit, build, maintain and operate stormwater features for your development project. Clark County's Water Quality is covered by County Code 13.26A including reduction of pollution in stormwater runoff. Clark County created a new Stormwater and Erosion Control code 40.386 in 2015 that outlines the regulations to protect stormwater during development projects (a .pdf file is available for review on the manual page). The Clark County Community Development staff can assist customers navigate the new regulations as it pertains to your specific project.
