Niwot gets water from Left Hand Water District, and the service line beyond the meter pit is private and belongs to the customer. When older interior pipe or that buried line starts failing, a plumber can replace it with PEX or copper. Call the number on this page to be connected with a local plumber in Niwot.

What happens when you call
You will be connected with an independent local plumber who works in Niwot. Expect questions about the age of the house, what pipe is visible at the water heater, where leaks have happened and whether flow has dropped. The plumber looks at exposed lines and the main shutoff, then recommends a repair, a partial repipe or a full one.
If the buried line from the meter pit is suspect, the plumber will explain how replacing it fits into the job.
What affects the price
- Interior pipe only, or interior plus the private service line
- Lot size, which sets the length of any yard run
- Basement, crawl space or slab
- PEX or copper
- Wall and ceiling patching
Niwot conditions
Niwot is a small unincorporated community on State Highway 119, about halfway between Boulder and Longmont, with a historic downtown along 2nd Avenue. The fact sheet does not include a year-built breakdown, so the build year of your own home is the best guide.
Water and sewer come from two separate special districts. Left Hand Water District, serving parts of Boulder, Weld and Broomfield counties since 1960, supplies water, disinfecting with chlorine and blending its own treated water with water bought from Boulder, Longmont and Central Weld County Water District. The district locates its lines only up to the meter pit; service lines beyond the meter pit are private and the customer's. Left Hand keeps a service line inventory, and customers can ask about their line's material at 303-530-4200. That record covers the buried line, not the pipe in your walls.
Sewer comes from Niwot Sanitation District, which makes each owner responsible for the whole sewer service line from the house to the main. That does not change a supply repipe, but it helps to know if drain work is also planned.
Because Niwot is unincorporated, building permits come from Boulder County Community Planning and Permitting, Building Safety and Inspection Services, at the Courthouse Annex in Boulder. Its page does not list plumbing permits by name, so the plumber should confirm what the job needs.
Checklist before the visit
- Find the meter pit location and the main shutoff in the house
- Ask Left Hand what material is on record for your service line
- List leaks and repairs
- Clear access to the water heater
