The Town of Nederland operates its own wastewater treatment plant, so a sewer line replacement here covers the private pipe from your house to the Town's sewer. At about 8,235 feet, cold and rocky ground make planning especially important. Call the number on this page to be connected with a local plumber in Nederland.

What happens when you call
You'll be connected with an independent local plumber who works in Nederland. Expect questions about whether you're on Town sewer, which drains back up and how long it's been happening. Before pricing a replacement, the plumber will usually camera the line to find the material, depth and location of each defect and to judge whether a trenchless method could follow the old route, which can matter a lot on rocky mountain ground.
The Town of Nederland issues its own building permits through its Building, Planning and Zoning Department and has adopted the 2024 ICC codes. Town Hall is at 45 West First Street, 303-258-3266. Some simpler permit types are One-Stop, while SAFEbuilt does plan review for others; the plumber can confirm what a sewer replacement needs.
What affects the cost
- Length and depth of the line to the Town sewer
- Rock, slopes and frost depth at high elevation
- Trench or trenchless, depending on whether the slope holds
- Decks, walls and access on steep lots
- Permit and inspection
Nederland's sewer and setting
The Town runs the Nederland Wastewater Treatment Plant, built in 2013, and notes its role in protecting Barker Reservoir and the waters downstream. For wastewater questions, the Town's line is 303-258-3088; no after-hours number is published, so call during the day if neighbors are backing up too. The Town's pages we reviewed don't say which outlying properties are on Town sewer or where its responsibility for a connection ends, so confirm both before work is priced.
Nederland is a former tungsten, silver and gold mining town at the junction of State Highway 119 and the Peak to Peak Highway, about 17 miles west of Boulder. At roughly 8,235 feet, freeze protection is a real concern, and winter frost and snow can make excavation slow. Older homes in town are the likeliest to have aging clay or cast iron drain lines, while newer ones generally have plastic pipe that fails from shifting soil or later digging.
Checklist before the plumber arrives
- Limit water use
- Clear snow and debris from around the cleanout
- Confirm on your bill that you're on Town sewer
- Note which fixture backs up first
- Make sure the drive is passable for equipment
