A Nederland sump pump that stops working usually has a float that will not lift, a check valve leaking back, a power fault or a worn motor, and at this elevation a frozen discharge line is a frequent suspect. A plumber can sort out which it is and keep the water out of the town sewer. Call the number on this page to be connected with a local plumber in Nederland.

How the visit goes
The number connects you with an independent plumber who serves Nederland. Expect questions about whether water is rising now, where the pit is, whether the outdoor line might be frozen and what the pump does when the float rises. On site, the plumber checks power, lifts the float, runs the pump through a full cycle and listens for water returning past the check valve. Then they follow the discharge outside, which in winter may mean digging out the outlet. You will hear whether a part, a new pump or a reworked discharge line is the fix.
Cost drivers
- One component versus a new pump
- Thawing, re-sloping or enlarging a frozen discharge
- Access to a crawlspace or basement pit
- Battery backup sized for mountain outages
- Permit work if new piping goes in
Nederland conditions
Nederland sits around 8,235 feet in southwestern Boulder County, at the junction of SH 119 and the Peak to Peak Highway, and cold-weather freeze protection is a practical concern. A sump discharge that holds water after each cycle can freeze solid overnight, leaving the pump running hot against a plug of ice. Spring melt then sends water toward foundations at the same time.
The Town of Nederland runs water and sewer, with its own wastewater treatment plant that helps protect Barker Reservoir downstream. That plant is for household wastewater, so a sump line into a floor drain or laundry sink should be moved outdoors. For wastewater questions, the town line is 303-258-3088. Town water meters typically sit inside the home, often in a crawlspace or basement, and the town's meter network watches for excessive use that could mean a leak. If a pit is filling and the meter keeps spinning, a supply leak may be the real source. Which outlying properties are on town service was not stated; on a private well, use a battery backup.
The Town of Nederland Building, Planning and Zoning Department issues permits under the 2024 ICC codes.
Before the plumber arrives
- Shut off the pump circuit if water is near the outlet
- Shovel a path to the discharge outlet
- Clear access to the crawlspace or basement pit and the meter
- Note whether you are on town water or a well
