The Town of Nederland operates its own wastewater treatment plant, and the pipe that carries sewage from a house to the town's lines is private plumbing. At about 8,235 feet, cold weather is a real factor in how those pipes hold up. Call the number on this page to be connected with a local plumber in Nederland.

After you call
You'll be connected with an independent local plumber who serves Nederland and the Peak to Peak area. Tell them which drains are backing up, whether the trouble started during a cold snap, and whether your home is on town sewer or a private onsite system. The plumber typically clears the line, runs a camera to see what's inside, and measures the depth and location of the problem. A frozen section, a crack, a sag or a root mass each call for a different fix, so the inspection comes before any quote.
If the trouble is in the Town's system, the Town's wastewater line is 303-258-3088. The Town doesn't publish a separate after-hours number on the pages we reviewed.
What shapes the cost
- Depth of the pipe and how much rock is in the way
- Snow, frozen ground or tight mountain lots that limit access
- Spot repair, liner or replacement
- Town building permit, issued under the 2024 ICC codes
- Insulating or rerouting a section that has frozen before
Local conditions in Nederland
Nederland is a small, high-elevation mountain town in southwestern Boulder County at the junction of SH 119 and the Peak to Peak Highway, about 17 miles west of Boulder. It began as a tungsten, silver and gold mining town and now serves as a gateway to Eldora and the Indian Peaks. The Town built its wastewater treatment plant in 2013 and notes its role in protecting Barker Reservoir and the water downstream. Which outlying properties are on town sewer wasn't stated, so homes outside the core may drain to private onsite systems; your bill will tell you.
At this altitude, freezing is the main enemy. A building sewer that runs shallow over rock, or one with a sag that holds water, can freeze in a long cold spell. Freeze and thaw cycles also work on joints. Older homes from the mining era may have cast iron or clay, while newer houses usually have plastic. The Town of Nederland's Building, Planning and Zoning Department at Town Hall, 45 West First Street (303-258-3266), issues building permits.
Checklist before the plumber arrives
- Stop running water in the house
- Shovel a path to the outdoor cleanout if there is one
- Note whether the backup followed a hard freeze
- Keep the house heated; don't use open flames to thaw pipes
