Most Firestone businesses get water from the Town, which buys it treated from Central Weld County Water District and St. Vrain Water Authority, while St. Vrain Sanitation District handles sewer. The town runs a backflow program and issues backflow preventer permits through its Building Division. Call the number on this page to be connected with a local plumber in Firestone.

Firestone's utilities
The Town of Firestone distributes water but doesn't treat it. It buys treated water from Central Weld County Water District, which draws from Carter Lake and treats it at the Carter Lake Filter Plant, and from St. Vrain Water Authority's Gould Well. The water is disinfected with chlorine, and Central Weld reports soft water, averaging 33 mg/L hardness. In the Barefoot Lakes neighborhood, Little Thompson Water District provides water instead. Sewer across Firestone, Frederick, Dacono and parts of Mead is St. Vrain Sanitation District, which says the building sewer line belongs to the property. Gas is Black Hills Energy.
Immediate steps
- Shut off the fixture valve, or the building's main if water is spreading.
- Stop using drains that are backing up.
- For a sewer backup that might be in the main, call St. Vrain Sanitation District's 24-hour staff at 303-776-9570.
- For a water emergency on the town system after hours or on weekends, call 720-652-4222.
- If anyone smells gas, get everyone out, then call 911 and Black Hills Energy using the number on the gas bill.
- Call the number on this page for a plumber on the private side.
Symptoms to watch
| Symptom | Likely cause |
|---|---|
| Several drains backing up together | A blockage in the building sewer line, which the property owns |
| Backflow device leaking after winter | Freeze damage or worn seals |
| Hot water fading during a rush | A heater undersized for the business |
| Running restroom fixtures | Worn flush valves or flappers |
| Wet ground near the meter | A leak on the service line |
What affects the price
The scope of the work sets the price first: fixture count, building size and access. Firestone started its backflow prevention and cross-connection control program in 2019 to meet the state rule, and the Building Division's fee schedule lists permits for residential and commercial backflow preventers. Town pages reviewed don't state a testing frequency or tester requirements, so ask the town. Central Weld County Water District, which supplies the town, requires annual testing of containment assemblies on its own commercial, irrigation, fire and multifamily services, but that rule covers Central Weld's customers, not necessarily the town's. Tankless water heaters with new gas piping need plan review, which adds time. After-hours scheduling and excavation also count. The town's service line inventory reports no lead lines.
