Hydro jetting cleans a Niwot home's sewer service line with a high-pressure water nozzle that cuts roots and removes grease and sludge along the pipe. Niwot Sanitation District makes owners responsible for that whole line, so keeping it clear falls to the homeowner. Call the number on this page to be connected with a local plumber in Niwot.

What happens when you call
The number on this page connects you with an independent plumber who works in Niwot. Describe which drains are affected, whether it's the lowest level of the house and whether the line has been cleaned before. If the district has already checked its main, say so.
At the house, the plumber locates a cleanout, often scopes the line, and jets from the house toward the district main. The rear-facing spray scrubs the full pipe wall and drives debris downstream; a camera pass afterward shows whether the line is clear or damaged.
What moves the price
- Access to the line and whether a cleanout exists
- Length of the service line to the main
- Roots from mature trees versus grease buildup
- Camera inspection
- After-hours timing
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. Water and sewer come from two separate special districts: Left Hand Water District for water, and Niwot Sanitation District for sewer. The sanitation district collects and treats Niwot's wastewater at its own plant and covers about seven square miles.
Its rules are specific. Each user constructs and maintains the entire length of the sewer service line, from the building drain to the main, and must repair leaks or breaks after notice. Only the district or its representative may make connections to district lines. For emergencies, the district's number is 303-652-2525, press 1. If the district's main is clear, the problem is in your line.
Older homes near downtown can have clay or cast iron service lines, where roots from mature trees work into the joints. Newer homes in the surrounding subdivisions are more likely plastic, where grease and wipes cause most clogs. Repairs in unincorporated Niwot are permitted by Boulder County's Building Safety and Inspection Services (303-441-3926).
Before the plumber arrives
- Call the district if neighbors are backing up too
- Stop running water in the house
- Clear access to the cleanout
- Skip chemical drain openers
A practical note: because only the district may connect to its lines, any repair at the tap end of your service line has to be coordinated with Niwot Sanitation District. A plumber can scope the line first so you know what to ask for.
