Frederick's water picture
Three entities supply drinking water inside Frederick: the Town, Left Hand Water District and Central Weld County Water District. The simplest rule is I-25. Everyone east of the interstate is a Town customer, including the Evanston area, while Left Hand Water District serves residents to the west. Town water is Colorado-Big Thompson supply from Carter Lake, treated at the Carter Lake Filter Plant.
The Town's pages don't say exactly where its pipe ends and the owner's begins, so if water is coming up at the meter, call the Town first; utility billing is (720) 382-5500 on weekdays. The Town has inventoried its service lines to classify their materials, and residents can request the inventory or ask about their own line at 720-382-5801.
Frederick began as the coal-mining town of McKissick and is now a fast-growing family suburb in the Carbon Valley. Older homes near Locust Street and the original town are the ones most likely to have aging lines. Newer subdivisions usually see a fitting fail or a line damaged by landscaping or soil settling.
Cost factors
- Section or full line. One leaking joint is a small job; a new service is larger.
- Distance and depth. Long setbacks and deep pipe mean more excavation.
- Surfaces. Driveways, patios and sprinkler systems need restoring.
- Entry point. Basement or slab construction affects how the line comes in.
- Permits and inspection. The Town of Frederick Building Department, 401 Locust Street, handles permits; inspectors may verify the plumber's identity at inspection.
Making the call
The number on this page links you to an independent local plumber who serves Frederick; Plumber Denver CO doesn't do the work. Tell them which side of I-25 you're on, where the water is showing and whether the meter moves with everything off. For a heavy leak, close the main shutoff in the house first. The plumber will locate the leak and explain whether a repair or a replacement fits.
