Black Hawk's City Water Department supplies drinking water to the whole city, but the sewer provider wasn't confirmed, so check your bill or ask the City who owns the main. The pipe from a building to that main is private plumbing a plumber repairs. Call the number on this page to be connected with a local plumber in Black Hawk.
About Black Hawk
Black Hawk is a former gold-mining settlement known as the City of Mills, now a small casino town of restored historic buildings along North Clear Creek that shares a National Historic District with Central City. It's Colorado's least populous city. Old buildings, steep gulches and rocky ground mean sewer pipe here can be old, deep or hard to reach, and the right repair depends on finding the problem precisely. Building permits go through the City's Community Planning and Development Building Division, which has contracted SAFEbuilt since 2015; questions go to cpdinquiry@cityofblackhawk.org.
What to do now
- Stop using water in the building so the backup doesn't spread.
- Close off the affected area and keep people away from any overflow.
- Look at your utility bill for the name of your sewer provider.
- If sewage is coming from the street or a manhole, contact that provider or the City.
- Note which fixtures backed up first and when it started.
Signs and likely causes
| Symptom | Likely cause |
|---|---|
| Lowest-floor drains back up first | Blockage in the building sewer |
| Gurgling as other fixtures drain | Partial restriction or venting problem |
| Repeat clogs after snaking | Cracked, offset or root-filled pipe |
| Slow drains in a cold snap | Ice in a shallow section |
| Sewer odor in a lower level | Dry floor drain trap or a leaking pipe |
The table is a starting point, not a diagnosis. In an old mill-town building, a single drain line may have been extended, rerouted or patched several times over the decades, and two different problems can sit a few feet apart. That's why a plumber in Black Hawk usually wants to see the whole run on camera before suggesting a fix. In commercial and mixed-use buildings, the backup may also affect other tenants, so let the building manager know early.
What affects the cost
- Pipe depth and rock on a steep canyon lot
- Historic foundations, walls or pavement over the route
- Liner, spot repair or replacement
- City permit and SAFEbuilt inspection
- Access for equipment on narrow streets
When you call, you'll be connected with an independent local plumber who serves Black Hawk and Gilpin County. Expect the plumber to clear the line, run a camera to locate the defect, and explain options before any digging starts.
