Lines, Hydrants & Meters
Transporting water from the stream to the treatment plants to your home requires teamwork by a skilled utility staff. Water Supply, Plant Maintenance, Meter Maintenance, Meter Reading, and Water Distribution employees work together for one common goal - to provide the residents of Thornton with quality water every day.
Did you know?
The city is replacing 25,000 residential water meters with meters compatible with Advanced Metering Infrastructure (AMI) technology. The replacement meters will be able to track hourly water usage data instead of monthly. This means the city—and water customers—will be able to detect water leaks and other high-water issues much sooner than in the past. For more information, click
Thornton has over 5,600 hydrants. The City's Hydrant Flushing Program is conducted once per year and cleans the entire waterline system to improve water quality. The program also ensures the proper operation of each fire hydrant.
The Water Distribution staff maintains 660 miles of water lines and related facilities, such as fire hydrants, valves, and water taps. They also respond to customer calls for water breaks and water pressure problems. If you experience problems with pressure or need to report a water break, please call 720-977-6500.
Meter Maintenance and Meter Reading personnel provide all services for water meters. Meter readings are obtained using electronic devices and transferred into the billing system. New meter pit inspections and installations are provided for new homes and businesses before occupancy. These requests are scheduled through Utility Billing to ensure all applicable fees are paid. You can contact Utility Billing at 303-538-7370 if you have questions about the new service or changes in your existing service.
Water Supply and Water Plant Maintenance
The Water Supply and Water Plant Maintenance staff works together to maintain 63 miles of supply ditches and 11 reservoirs. Continuous monitoring of 16 pump stations, two water treatment plants, and 9 potable water storage tanks ensures utility customers uninterrupted water service.
