Sewer Line Repair in Louisville, CO

The call and the visit

You'll be connected with an independent local plumber who serves Louisville. Describe which fixtures are backing up and whether the house was rebuilt or remodeled recently. Most plumbers begin by clearing the blockage, then send a camera through the line to find its condition and the location of any defect. If the main is the problem, the City handles it: Public Works Operations takes sewer backup calls at 303-335-4750 on weekdays from 7 a.m. to 3:30 p.m., and its on-call line, 303-489-2301, covers after 3:30 p.m.

Cost considerations

• Depth and length of the damaged section
• Whether it runs under lawn, a driveway, a deck or trees
• Spot repair, lining or full replacement
• City of Louisville permit and plumbing inspection
• Working around new landscaping on rebuilt lots

Local conditions

Louisville is a former coal-mining town in southeastern Boulder County that became a suburban community with a historic downtown and about 32 miles of trails. Hundreds of homes were rebuilt after the December 2021 Marshall Fire. A rebuilt house may sit on a brand-new lateral or may have been tied into an existing one, so the age of the house doesn't always tell you the age of the pipe underneath. The older blocks near downtown can have clay or cast iron laterals, where roots and corrosion are the usual issues.

The City runs its own wastewater treatment plant, built in 2017 with UV disinfection, on the east side of town, discharging to Coal Creek, with some treated water reused for park and golf course irrigation. The City's Building Safety Division, on the first floor of City Hall at 749 Main Street (303-335-4584), reviews permits and performs plumbing inspections.

A short pre-visit checklist

• Stop water use until the line is cleared
• Find the cleanout and clear the area around it
• If the home was rebuilt, have any plans or as-built notes handy
• Call Public Works first if sewage is coming from the street
• Keep pets and kids away from any overflowing drain

Avoid chemical drain openers while you wait. They don't clear roots or fix a broken pipe, and they make the line unpleasant and unsafe for the person who opens it.
