Niwot's water is supplied by Left Hand Water District, which replaced the wells and cisterns early residents relied on, so most homes here are on district water rather than a private pump. If your property still runs a well, a plumber can test the pump, switch and tank; on district water, low pressure usually starts at the regulator or service line. Call the number on this page to be connected with a local plumber in Niwot.

When you make the call
This site is a free referral service, not a plumbing company. You'll be connected with an independent local plumber who works in Niwot. Tell them whether you're on Left Hand water or a well, whether the water is off or weak and how long it has been going on. Left Hand Water District is at 303-530-4200 on weekdays from 8:30 a.m. to 4:30 p.m.; the district publishes no separate after-hours line.
On a well, the plumber checks the breaker, switch, tank charge and pump current. On district water, they test static pressure, look at the regulator and listen for leaks along the line from the meter.
Things that affect cost
- For a well: the failed part, pump depth and tank condition
- For a well: the age of the equipment, if the well predates the district
- For district water: regulator, valve or service line work
- Digging around mature trees and landscaping
- Boulder County permits for the work
Water in Niwot
Niwot is a small unincorporated community on the Diagonal Highway about halfway between Boulder and Longmont, with a historic downtown along 2nd Avenue. Left Hand Water District, which has served parts of Boulder, Weld and Broomfield counties since 1960, supplies its water. The district draws on Lefthand Creek, Colorado-Big Thompson water from Carter Lake and the Williamson Ditch, and buys water from Central Weld County Water District and the cities of Boulder and Longmont. It disinfects with chlorine.
Before Left Hand's system, early Niwot residents relied on wells and cisterns. Whether any homes still use private wells today hasn't been verified, so we won't guess. If your property has a capped wellhead and a pressure tank, you have a well system and its upkeep is yours.
Sewer comes from a separate district, Niwot Sanitation District, which runs its own treatment plant and makes the property owner responsible for the whole sewer service line from the house to the main. Niwot is unincorporated, so building permits come from Boulder County's Building Safety and Inspection Services at 303-441-3926.
Before the plumber arrives
- Check your bill to confirm Left Hand is your water provider
- On a well, read the tank gauge and check the pump breaker
- See whether the problem affects every tap
- Look for wet ground between the street and the house
- Find the main shutoff valve
