Construction will begin in the summer of 2026 on a new water treatment plant that will nearly double the City of Las Vegas’ water capacity and ensure safe drinking water for generations to come.
The City of Las Vegas’ new water treatment plant, designed in partnership with the New Mexico Environment Department, will include critical upgrades to the City’s water treatment systems, including optimized pre-treatment to improve removal of cloudiness and natural debris, as well as granular activated carbon filters, which will reduce dissolved materials that can cause taste, odor, or discoloration.
The general site location has been decided, and the design is underway. The advanced treatment plant will have an initial capacity of 3.56 million gallons per day — a significant improvement over the City’s existing 2.5-million-gallon system. The facility will serve a population of approximately 14,880.
To accommodate future growth and assure long-term water security, the design also includes the ability to efficiently expand the plant’s capacity to 5 million gallons per day, supporting the City’s anticipated needs for decades to come.
The project builds on ongoing improvements to the City’s drinking water and wastewater systems in recent months, including installing new pretreatment filter beds, clearing debris and sediment from the Gallinas River, and extending and replacing overflow drains.
Construction of the City of Las Vegas’ new water treatment plant is funded by the Federal Emergency Management Agency Claims Office and state funding provided in response to the devastating impact of the Hermits Peak/Calf Canyon Fire and subsequent flooding, which caused system-wide outages and boil water advisories.
