Customers may notice temporary changes in taste or odor, water remains safe to drink
EL PASO – As EPWater welcomes river water this week, it will begin the seasonal transition to treating Rio Grande water at two of its water treatment plants, helping meet increased customer demand during the summer months while preserving the region’s groundwater resources.
As water reaches customers, some may notice temporary changes in the taste or odor of their drinking water. It is important to emphasize the water remains safe to drink and continues to meet or go beyond all federal and state drinking water standards.
“Providing safe, high-quality drinking water is our highest priority,” said Richard Wilcox, Chief Water Quality Compliance Officer. “As river water moves through the utility’s network of pipes and storage tanks, it may take several weeks for the system to fully adjust to the seasonal change in water source.”
During periods of extreme heat, naturally occurring algae in the Rio Grande may become more active, which can occasionally cause slight changes in the taste or odor of drinking water. When this occurs, EPWater adjusts its treatment processes to effectively address these changes while maintaining water quality and safety.
To ensure a safe water supply, EPWater uses chlorine to disinfect drinking water. Chlorine has been used by municipal water systems across the United States since 1908 and remains one of the most effective methods for maintaining safe drinking water as it travels through distribution systems.
River water plays a critical role in El Paso’s long-term water management strategy. By using the Rio Grande, the utility reduces reliance on groundwater and help preserve local aquifers for future generations.
EPWater operates under strict federal and state regulations, following standards established by the U.S. Environmental Protection Agency and oversight from the Texas Commission on Environmental Quality.
