Water Treatment
Southern Nevada's water is treated first with ozonation to kill any potentially harmful microscopic organisms. It passes through a multistage filtration system to remove particles from the water. As the water leaves the treatment facilities, chlorine is added to protect it on the way to your tap. It also is treated to prevent pipelines from corroding.

Alfred Merritt Smith Water Treatment Facility
Built in 1971, the Alfred Merritt Smith Water Treatment Facility currently treats most of the valley's drinking water. The facility can treat up to 600 million gallons of water per day (mgd).

River Mountains Water Treatment Facility
The River Mountains Water Treatment Facility opened in 2002 and currently can treat up to 150 mgd. As the need arises, the River Mountains facility will expand to treat up to 600 mgd.

Ozone treatment
Ozonation is a water treatment process that destroys bacteria and other micro-organisms. It's one of the most advanced water treatment processes in the industry.

Although ozone is a very strong disinfectant, it doesn't remain in water for very long. For that reason, chlorine is added to protect the water while it is in the distribution system. The amount of chlorine used in the entire water treatment process will be significantly reduced, which should help improve the taste or our water.
