The City of Lafayette treats its wastewater at its own Water Reclamation Facility, and the pipe from your house to the city main is private plumbing. When that pipe clogs or breaks, a plumber makes the repair. Call the number on this page to be connected with a local plumber in Lafayette.

Lafayette in brief
Lafayette is a suburban city in southeastern Boulder County that grew from a coal-mining and farming past, with an Old Town core along Public Road. The city-operated Water Reclamation Facility, designed for up to 4.4 million gallons a day, releases treated water to Coal Creek. For weekend or after-hours sewer backups, Lafayette directs residents to Boulder County Dispatch at 303-441-4444; during the day, Public Works is at 303-661-1277. Older homes near Old Town may have clay or cast iron laterals, while newer subdivisions mostly have plastic.
What to do right away
- Stop using water throughout the house.
- Keep the area around the overflow clear.
- Check with neighbors; if they're backed up too, call Public Works or, after hours, Boulder County Dispatch.
- Find the cleanout and make it reachable.
- Don't pour chemical openers into the line.
Common symptoms
| Symptom | Likely cause |
|---|---|
| Floor drain overflows during laundry | Restricted building sewer |
| Roots on the cable after clearing | Root entry at older joints |
| Slow drains in every bathroom | Main line blockage |
| Clogs that return within weeks | Crack, offset joint or sag |
| Odor near the foundation | Leaking pipe or dry trap |
Lafayette's housing spans a wide range, from older homes around the Old Town core to newer subdivisions elsewhere in the city. Pipe material usually follows the age of the house. In the older blocks, mature trees and clay joints make roots the usual suspect. In newer areas, problems tend to come from shifting soil or later construction. Either way, a cleaning alone only restores flow, and if the line clogs again within months, something in the pipe is catching debris; the camera run afterward shows whether the pipe itself needs attention, and the footage is worth keeping for future reference.
Cost factors
- Pipe material, depth and length of the bad section
- Trees, driveways or patios over the route
- Spot repair, liner or replacement
- A City of Lafayette building permit (Building Division inspection line 303-604-3822)
- Restoring landscaping afterward
When you call, you'll be connected with an independent local plumber who serves Lafayette. The plumber will clear the line, run a camera to find the defect and explain options. Lafayette's Building Division takes permit drop-offs at City Hall, 1290 S. Public Road.
