In Castle Rock, replacing a sewer line means new pipe for the private line between your house and the public sewer. Some addresses with a Castle Rock mailing address are served by other districts, so confirm your provider on your bill before work starts. Call the number on this page to be connected with a local plumber in Castle Rock.
Castle Rock is the Douglas County seat and a large, growing town on I-25, with Castle Rock Water as the town's water utility. Our fact sheet did not confirm the sewer provider for every address or where its responsibility ends, and some properties with Castle Rock mailing addresses, such as The Village at Castle Pines, are served by other districts. Your utility bill is the place to check before any digging is planned. Ask that provider where its part of the sewer stops, because that point decides how much of the pipe is a private replacement and how much, if any, is the provider's to fix.
What to do now
- Cut water use. Every flush and load of laundry adds to the backup.
- Check whether neighbors have the same problem. If so, contact the sewer provider listed on your bill, since the main may be the issue.
- Find and uncover the cleanout. It makes clearing and filming the line faster.
- Have the line cleared and inspected by camera. That shows whether it's one defect or the whole run.
- Ask about the permit. The Town of Castle Rock runs its own building permit process; the plumber can confirm what a sewer replacement requires.
Symptom and likely cause
| Symptom | Likely cause |
|---|---|
| Clog returns within weeks | Roots, a break or a belly holding debris |
| Lowest drain in the house fills first | Main-line blockage |
| Gurgling from unused fixtures | Air pushed back by a restricted line |
| Damp, sunken or extra-green strip of yard | Leaking or broken pipe underground |
| Camera shows standing water in one section | Pipe has sagged and lost slope |
Cost factors
- How long and how deep the line runs to the public sewer
- Trenchless methods where the route still holds grade, open trench where it doesn't
- Hardscape, landscaping and irrigation along the route
- Rocky or hard ground, which can slow excavation
- Interior drain pipe that should be replaced at the same time
- Permit and inspection fees set by the Town
Because much of Castle Rock's growth is recent, many homes have plastic sewer pipe that fails in one spot rather than everywhere. That makes the camera inspection especially worth having before you agree to replace the full length.
