Water, sewer and gas in Frederick
Frederick has three water suppliers inside town limits, and I-25 is the main dividing line. Everyone east of I-25 is a Town of Frederick water customer, including the Evanston area, while Left Hand Water District serves residents west of I-25. Central Weld County Water District also serves part of town. Town water is Colorado-Big Thompson water from Carter Lake, treated at the Carter Lake Filter Plant and disinfected with chlorine. The Town's water and utility billing line is (720) 382-5500 on weekdays from 8 a.m. to 5 p.m. If you are west of I-25, call Left Hand Water District instead.
Sewer comes from St. Vrain Sanitation District, which also serves Dacono, Firestone and parts of Mead. The district treats the building sewer line as the property owner's responsibility and keeps staff on a 24-hour line for backups at (303) 776-9570. If only your house is backing up, a plumber clears your line; if the problem is in the district main, St. Vrain handles it.
Natural gas comes from Black Hills Energy. Keep the emergency number from your gas bill somewhere you can find it in the dark.
What affects the cost
- Timing. After-hours, weekend and holiday visits usually cost more.
- Access. A leak in an unfinished basement is faster to reach than one behind drywall.
- Scope. A single fitting is quick; a tank replacement or a sewer line repair takes longer.
- Inspection. The Town of Frederick Building Department handles permits and inspections, and inspectors may verify the identity of the plumber of record on permitted work.
What happens when you call
You will be connected with an independent plumber who serves Frederick. Tell them what failed, whether the main is off and which side of I-25 you are on. Ask about after-hours pricing first. Arrival depends on the hour and the plumber's schedule, so none is promised.
