St. Vrain Sanitation District provides Firestone's sewer service and says the building sewer line belongs to the property, not the district. When that pipe clogs, sags or breaks, a plumber makes the repair. Call the number on this page to be connected with a local plumber in Firestone.

Firestone's setup
Firestone is a fast-growing town in southwest Weld County along I-25, one of the Carbon Valley towns with Frederick and Dacono, made up mostly of newer family subdivisions. St. Vrain Sanitation District handles sewer and keeps staff on call for backups at 303-776-9570. Water is a separate matter: the Town distributes it to most of town, while Barefoot Lakes gets water from Little Thompson Water District, but sewer responsibility for the building line is the same everywhere. Newer plastic laterals usually fail from settling, separated joints or damage during later digging.
What to do now
- Stop running water in the house.
- Keep pets and kids away from the overflow.
- Ask neighbors whether they're affected; if so, call St. Vrain Sanitation District.
- Find the cleanout, often near the foundation outside.
- Note when it started and which fixtures are affected.
Symptom and cause
| Symptom | Likely cause |
|---|---|
| Same clog keeps coming back | Sag in the line from settled backfill |
| Basement drain fills as the washer empties | Main line restriction |
| Trouble began after fence or sprinkler work | Pipe damaged by digging |
| Toilets gurgle | Partial blockage downstream |
| Soft or sunken spot in the yard | Separated joint leaking into soil |
Because Firestone grew quickly, many lines were installed during busy construction years, and the backfill around them has been settling ever since. A small sag holds a little water and catches solids; over months it becomes a recurring clog that snaking only fixes briefly. Sprinkler trenches, fence posts and tree plantings added after move-in are another frequent source of damage. If any yard work happened recently, mention it when you call, since it often points straight to the spot. Keep the cleanout cap accessible and free of mulch or rock so the plumber can start right away.
Cost factors
- Depth and distance to the defect
- Driveways, patios or landscaping over the line
- Spot repair, liner or replacement
- Town of Firestone Building Division permit (9950 Park Ave.)
- Restoring sod and sprinklers afterward
When you call, you'll be connected with an independent local plumber who works in Firestone. The plumber typically clears the line, runs a camera to find and measure the problem, and explains whether a single repair will do.
