Garnet Valley Water and Wastewater Systems

View all


The Apex Industrial Park is one of Southern Nevada’s largest industrial parks located in Garnet Valley in North Las Vegas. The 16-parcel industrial park includes more than 11,000 acres and is attracting technology- and manufacturing-based businesses.

When completed, the Garnet Valley Water System will support the water needs of the industrial area. The Garnet Valley Water System will consist of facilities to support supplying 20 million gallons per day (MGD) at full build-out and includes:

  • 18 miles of pipeline, 16 inches to 36 inches in diameter
  • 1 reservoir (4 million gallons)
  • 3 pumping stations with a capacity of 5 MGD
  • 2 forebays
  • 2 Rate-of-Flow Control Stations (20 MGD total)

Southern Nevada maximizes its water resources by treating and recycling 99 percent of the water used indoors in its service area. Treating wastewater and returning it to Lake Mead extends the availability of our water resources through return-flow credits.

Construction of the Garnet Valley Wastewater System will help ensure the sustainable development of resources and reduce water demand impacts to the Colorado River. The wastewater project will support the SNWA’s efforts to maximize our water resources by developing the infrastructure required to capture indoor wastewater from the Garnet Valley area and transport it to existing treatment facilities in accordance with SNWA’s out-of-valley water use policy. The project consists of:

  • 5 wastewater lift stations
  • 43 miles of wastewater pipeline from 8 inches to 48 inches in diameter
  • 8 miles of force main pipe from 14 inches to 30 inches in diameter

The Garnet Valley Water System is estimated to cost $129.8 million with completion in 2028. The Garnet Valley Wastewater System is estimated to cost $120.0 million with completion in 2027.
