The Town of Lyons runs its own wastewater plant and maintains the Town sewer mains, while homeowners are responsible for the sewer line from their property to the Town main. When that line fails, a plumber makes the repair. Call the number on this page to be connected with a local plumber in Lyons.

Lyons in brief
Lyons is a small foothills town in northern Boulder County where North and South St. Vrain Creeks meet, ringed by red sandstone hills. The Town's Wastewater Division operates its own treatment plant and maintains Town-owned mains with jet cleaning, video inspection and manhole rehabilitation. The private line to the main is the owner's, and the Town asks residents not to flush wipes, even ones labeled flushable, and not to pour grease down drains. For after-hours emergencies, the Town lists 303-441-4444.
What to do now
- Stop using water in the house.
- Keep everyone away from the overflow.
- If neighbors are backing up too, call the Town.
- Find the cleanout and clear access.
- Think back to recent wipes or grease going down the drain and tell the plumber.
Symptom guide
| Symptom | Likely cause |
|---|---|
| Sudden backup after heavy use | Wipes or grease blockage |
| Roots on the cable when cleared | Root entry at old joints |
| Every drain slow | Main line restriction |
| Clogs return soon after clearing | Crack, sag or offset joint |
| Wet ground along the route | Leaking lateral |
Lyons sits on sandstone and creek-bottom soils, and lots range from the historic downtown blocks to homes tucked against the hillsides. Laterals in older parts of town may be clay or cast iron, where roots and corrosion are common. On sloped lots, a line can run deeper or cross rock, which makes digging slower and a precise camera location more valuable. Because the Town's own crews already video-inspect the mains, a plumber's camera run of your lateral fills in the private side of the picture and shows where the trouble really starts. Mention any history of wipes or grease problems too.
Cost factors
- Depth and the rocky foothill ground around the pipe
- Trees, walls or driveways over the line
- Spot repair, liner or replacement
- A Town building permit through SAFEbuilt's Community Core system (permit technician 970-545-3512)
- Restoring landscaping afterward
The Town contracts SAFEbuilt for all building department work, and Boulder County has no building code jurisdiction inside town. When you call, you'll be connected with an independent local plumber who serves Lyons and can clear, scope and repair the line.
