Phases 1-4 ~ January 2023 to Present

Since January 2023, the City of Greeley has been inspecting and replacing water service lines that contain lead or have been classified as Galvanized Requiring Replacement—for free.

As of April 4, 2026, the City has identified the type of material used in water service lines at over 2,500 properties. The material of these lines was previously unknown. This is completed by hydro excavating a small hole (potholing) near the water service meter to visually identify lead, galvanized steel or non-lead water service line segments.

Buildings built before 1940 have the highest possibility of having a lead or a galvanized steel pipe that had been downstream of a lead water service line. Buildings built between 1940 and 1960 are being investigated and the water service lines may need to be potholed. The City has not encountered or identified lead pipes on any properties built after 1940. Homes built after 1981 in Greeley have no risk of a historical lead pipe, as the city plumbing code banned the use of lead piping in 1980, preempting national and state-wide bans.
