The New Mexico Environment Department, in collaboration with the City of Las Vegas, has completed several upgrades to the city's drinking water and wastewater systems. These improvements aim to support recovery efforts following the Calf Canyon/Hermits Peak Fire. The enhancements include new water transmission lines, advanced drinking water filter systems, and monitoring technology to ensure reliable and safe water for residents.
Environment Secretary James Kenney said, "Las Vegas residents are the beneficiaries of the Environment Department’s collaboration with the City of Las Vegas." He emphasized that these upgrades utilize modern technology to provide safe drinking water for families and businesses in the future.
As of August 19, several key improvements have been made. A new pretreatment system was installed to strengthen the drinking water system against potential flooding. Debris and mud were cleared from the Gallinas River, and a sediment pond was constructed near the reservoir to mitigate flooding and contamination risks. Two drinking water treatment filters are being upgraded by removing old materials to enhance water quality.
Additionally, an annual Consumer Confidence Report was completed and submitted, providing residents with updated information on their drinking water quality. Overflow drains were extended, and a concrete pad was built under the Valencia Storage Tank to prevent erosion. The wastewater treatment system's vacuum system was replaced for more efficient removal of scum and debris from the Gallinas River.
The 2025 Consumer Confidence Report indicated that while most state contaminant regulations were met, trihalomethanes levels exceeded average limits. The City of Las Vegas has informed customers about this issue in line with state regulations.
Despite these challenges, officials have confirmed that Las Vegas's drinking water remains safe (source). Both NMED and city authorities continue to monitor post-fire runoff effects on the city's water supply closely.
Plans are underway for a new water treatment plant, with construction expected to begin in 2026.
