Black Hawk is Colorado's least populous city, a former gold-mining settlement whose city water department supplies the whole town from two of its own treatment plants. When older supply pipe keeps leaking, a plumber can replace it with PEX or copper. Call the number on this page to be connected with a local plumber in Black Hawk.
Black Hawk in brief
Black Hawk was known as the City of Mills during the gold rush and is now a small casino town of restored historic buildings along North Clear Creek, sharing a National Historic District with Central City. The fact sheet has no year-built data, so the age of your own building is the best guide. The City of Black Hawk Water Department supplies the entire city from two plants: Dory Hill, which uses membrane microfiltration on North Clear Creek water, and Hidden Valley, near I-70 east of Idaho Springs, which uses conventional treatment with pressure filters for iron and manganese. Water from Hidden Valley travels about seven miles through three pump stations before reaching a tank on Miners Road. Both plants disinfect with chlorine gas and add soda ash for corrosion control. The pages reviewed do not say where the city's responsibility for the service line ends, so the plumber should confirm before replacing any buried line.
What to do now
- Shut off the water at the fixture or main if a line is leaking.
- Keep heat on during cold weather; mountain freezes are a leading cause of breaks.
- Record each leak and whether it was on a fitting or the pipe.
- Look at exposed pipe in the basement or crawl space.
- Delay finish repairs until the scope is known.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Splits after a cold night | Freeze damage in an exposed run |
| Leaks in several places | Aging pipe throughout the building |
| Weak flow everywhere | Narrowed galvanized steel |
| Rust tint at the first draw | Corroding steel pipe or fittings |
| Mixed materials in old buildings | Decades of repairs and renovations |
Cost factors
- Building age and construction, including historic masonry
- Steep sites and tight access
- Rerouting and insulation against freezing
- PEX or copper
- Patching after openings
The City of Black Hawk Community Planning and Development Building Division, with services contracted to SAFEbuilt since 2015, handles building permits; questions go to cpdinquiry@cityofblackhawk.org. Its page does not mention plumbing permits specifically, so the plumber should confirm what the job requires. In historic buildings with masonry walls, new lines are often run through existing chases, basements and closets rather than cut into stone, which can shape both the schedule and the cost. Ask the plumber to explain the planned routes before work begins.
