Firestone's sewer is provided by St. Vrain Sanitation District, which says the building sewer line belongs to the property owner, not the district. So clogs from the fixtures out to the district's main are a plumber's job. Call the number on this page to be connected with a local plumber in Firestone.

About Firestone
Firestone is a fast-growing town in southwest Weld County along I-25, one of the Carbon Valley towns with Frederick and Dacono. Most of it is newer family subdivisions. St. Vrain Sanitation District provides sewer service across Firestone, Frederick, Dacono, parts of Mead and nearby unincorporated Weld County, and it staffs a 24-hour line for sewer backups at (303) 776-9570. The district handles its mains; the building sewer from your house out is yours.
Newer homes usually have plastic drain lines. Those lines rarely fail, but they clog when grease, wipes, hair and food go down them, and construction debris can linger in lines of brand-new houses. Water service is split, too: the Town of Firestone supplies most homes, while Little Thompson Water District serves Barefoot Lakes. That split affects who you call about water; for sewer, the provider at your address is shown on your bill. A plumber who works in the Carbon Valley will know the district's routine for backups that reach the main.
What to do first
- Check whether it's one fixture or many. One slow drain is local; water rising in a tub or floor drain when something else runs means the main.
- Stop running water if the main is involved.
- Protect the basement. Move belongings away from floor drains and lower-level showers.
- Skip chemical drain openers. They seldom work on a main line and make the pipe hazardous.
- Call a plumber for the private line, and St. Vrain Sanitation if the plumber finds the main is the problem.
