Las Vegas treats and returns nearly all indoor wastewater to Lake Mead, earning return-flow credits that effectively triple the city's Colorado River allocation.
Indoor water used in Las Vegas homes is collected by the Clark County Water Reclamation District, treated at advanced facilities, and discharged into the Las Vegas Wash where it flows back to Lake Mead. Each gallon returned earns a return-flow credit allowing SNWA to draw an extra gallon from the Colorado River. Reclaimed (purple-pipe) water also irrigates many golf courses, parks, and median plantings under NRS 445A. Residential connections to reclaimed water mains are not permitted, but new commercial developments near transmission lines must connect when feasible.
Unauthorized cross-connections between potable and reclaimed systems trigger immediate service disconnection and require certified backflow inspection before restoration. Civil penalties reach $5,000 per violation.
