Water System Operations

Greeley has a complex water system with more than 500 miles of pipeline, 2 water treatment plants, a wastewater reclamation plant, 3 treated water reservoirs, 6 raw water reservoirs, and an extensive non-potable water system. Greeley's water system is efficient. Our water loss rate is about 5 to 6%, which is lower than the industry standard of 10%. To keep Greeley 's water system as efficient and effective as possible, we maintain and repair the existing system and upgrade system capacity in a timely manner.
