Backflow Prevention Program

The purpose of the Backflow Prevention Program is to effectively prevent the contamination or pollution of the City of North Las Vegas water system due to cross-connections, as required under North Las Vegas Municipal Code 13.20 Backflows and Cross-Connections. A cross-connection is any arrangement where a potable water source is directly or indirectly connected to a non-potable water line (i.e., the connection of a park drinking fountain to the surrounding landscape irrigation).

Backflow is the undesired reverse flow of used water back into the public water supply. Backflow can occur in many places including the following:

  • Pool and spa pump rooms
  • Landscape irrigation systems
  • Fire sprinkler systems
  • Bathroom and kitchen sinks
  • Laundromats

Backflow prevention devices are required on all industrial and commercial properties and must be tested annually with an approved backflow testing company. For more information and resources on this program, click here.

Industrial Wastewater Pretreatment Program

The Industrial Pretreatment Program protects the City’s wastewater collection system by establishing procedures to control and reduce the dumping of potentially harmful pollutants originating at industrial and commercial properties. Such pollutants include:

  • Fats, oils, and greases (FOG)
  • Pesticides
  • Fuels
  • Paints
  • Heavy Metals

The City of North Las Vegas Industrial Pretreatment Program complies with the U.S. Environmental Protection Agency (EPA) regulations (40 CFR 403). Facilities required to participate in the program must install, maintain and use pretreatment equipment that removes pollutants before they can enter the wastewater collection system. Businesses may also be required to obtain a permit. For more information on this program, click here.
