The Town of Nederland runs its own water and sewer, and businesses fill out a cross-connection and backflow questionnaire describing food prep, heating, sprinkler and irrigation uses. Meters usually sit inside the building, and the owner maintains them. Call the number on this page to be connected with a local plumber in Nederland.

When you call
You'll reach an independent local plumber who takes commercial work in Nederland. Describe the business, the problem and whether water is off. At this altitude, frozen pipes are a common reason for a call, so mention whether the building lost heat. Ski-season and summer businesses often prefer repairs in the shoulder seasons, so say if timing matters.
For a water heater or furnace replacement, the Town offers One-Stop permits that it often processes the same day. Applications go to Town Hall at 45 West First Street, 303-258-3266. The Town has adopted the 2024 ICC codes, and SAFEbuilt does plan review for some permit types.
What affects the cost
- Freeze damage and how much piping needs replacing
- Access to meters and piping in crawl spaces or closets
- Any backflow equipment the Town's questionnaire turns up
- Travel and winter road conditions
- Permits and off-hours work
Nederland's water and sewer
Nederland sits at about 8,235 feet at the junction of Highway 119 and the Peak to Peak Highway. The Town draws water from Middle Boulder Creek, treats it at its own plant with chlorine and maintains the water lines. Its 2026 report lists no health-based violations. Wastewater goes to the Town's treatment plant, built in 2013, which the Town notes helps protect Barker Reservoir downstream. Which outlying properties are on town sewer or water wasn't stated, so ask if you're on the edge of town.
Meters here are usually inside the building, in a crawl space, basement, utility closet near the water heater or under a sink, and customers are responsible for maintaining the meter and reader and keeping access clear. The meter reading network watches for excessive water use that could point to a leak, which can be an early warning for a business closed over a weekend. The Town is inventorying service line materials and will share a copy on request.
For backflow, the Town's Water Department asks facilities to complete a questionnaire reporting water uses such as food prep, heating and cooling equipment, fire sprinklers and irrigation, plus any backflow preventer on the main line. Testing frequency wasn't stated, so ask the Utilities Supervisor. Utilities can be reached at 303-258-3266, extension 4010. The gas utility wasn't confirmed; check the bill.
