Most of Castle Pines gets wastewater service from the Castle Pines North Metropolitan District, while the private sewer pipe from each house to the district's main is a plumbing repair. The City of Castle Pines treats sewer line repair or replacement as a 1-Stop permit. Call the number on this page to be connected with a local plumber in Castle Pines.

Clues the main line is involved
- Toilets gurgle when the washing machine drains
- Wastewater shows up in a lower-level shower
- All fixtures slow down at once
- The same clog returns within a month
- A wet or sunken strip of yard along the pipe route
A clog in one bathroom sink or a single toilet is usually local to that fixture. The pattern that matters is several drains acting up together, or the lowest drain in the house taking on water when fixtures upstairs are used. That points to the building sewer, the single pipe that carries everything out to the district's main.
Local setup
Castle Pines is a young home rule city, incorporated in 2008 from the Castle Pines North community along I-25 in northern Douglas County. The Castle Pines North Metropolitan District provides both drinking water and wastewater service there. The Village at Castle Pines, just south of the city, is served by a separate district, so the provider depends on the address and is named on your bill.
The City of Castle Pines Building Department lists water and sewer line repair or replacement as a 1-Stop permit, with inspections by City staff and permits managed in CommunityCore. Questions go to 303-705-0227. Because the community is relatively new, most sewer pipe here is plastic. Problems tend to come from shifting soil, root intrusion at fittings or damage from later landscaping projects rather than old pipe wearing out.
What changes the price
- Depth and length of the section that failed
- Hardscape over the line, such as a driveway, patio or retaining wall
- Repair method chosen after the camera inspection
- The City's 1-Stop permit and inspection
- Whether a cleanout exists or needs to be added for access
What to expect
You'll be connected with an independent local plumber who works in Castle Pines. Mention which fixtures are affected and whether the problem started suddenly or built up over time. Until the visit, keep water use light. The plumber will typically clear the line, put a camera down it to see the defect, and then walk you through a repair plan and the permit it needs. If the camera shows the defect is at or beyond the property line, the plumber can help you decide whether to involve the metropolitan district before any digging starts.
