North Las Vegas Wastewater Treatment Facility (WWTF) - Las Vegas, Nevada

The North Las Vegas Wastewater Treatment Facility (WWTF) is a municipal treatment plant located in the Las Vegas Valley, Clark County, Nevada. It serves a population of approximately 120,000 residents in the North Las Vegas area, operating as part of the region's water reclamation infrastructure. As a major treatment facility in the arid Southwest, the plant is subject to the U. S. Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting. For a population of this scale, advanced secondary or tertiary treatment is typical to meet stringent nutrient and pollutant limits, especially given the sensitivity of the receiving waters. The treated effluent is discharged into the Las Vegas Wash, which flows into Lake Mead on the Colorado River. Lake Mead is a critical water supply reservoir for the region and supports diverse aquatic life. The plant's operations are essential for protecting downstream water quality in the Colorado River system.

The plant discharges into the Las Vegas Wash, a man-made channel that carries urban runoff and treated wastewater to Lake Mead on the Colorado River. Lake Mead is a major reservoir in the Mojave Desert, providing drinking water and irrigation to millions. The downstream Colorado River supports a fragile desert ecosystem and is home to several sensitive fish species. Protecting water quality in this basin is crucial due to high evaporation rates and low natural dilution.
