The Town of Lyons runs its own wastewater plant and maintains the Town sewer mains, while residents are responsible for the sewer line extending from their property. Replacing that line is the fix when it has failed along much of its length. Call the number on this page to be connected with a local plumber in Lyons.
Lyons is a small foothills town where North and South St. Vrain Creeks meet, ringed by red sandstone hills, with a historic downtown on US 36 and State Highway 7. The Town's Wastewater Division operates its own treatment plant and maintains Town-owned sewer mains with jet cleaning, video inspection and manhole rehabilitation. Residents and business owners are responsible for the sewer line running from their property to the Town main. Town service covers properties within town limits; 80540 addresses outside town weren't verified.
What to do now
- Stop sending water down the drains until the line is checked.
- Check whether it's just your house. If neighbors are affected, call the Town; after hours and in emergencies, the number is 303-441-4444.
- Uncover the cleanout so the line can be cleared and filmed.
- Get a camera inspection. It shows whether there's one defect or a line that has worn out end to end.
- Plan the permit. The Town contracts SAFEbuilt for all building department work; Boulder County has no building code jurisdiction inside town.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Clogs that keep returning | Roots, a break, or wipes and grease built up in the line |
| Lowest drain backs up first | Main-line blockage on the private side |
| Gurgling fixtures | Restricted flow |
| Wet or smelly ground over the line | Cracked or separated pipe |
| Camera shows a low spot | Sag from settled or shifted soil |
Cost factors
- Length and depth of the line to the Town main
- Rock or sandstone near the surface, which slows digging
- Trench versus trenchless, depending on whether the slope is intact
- Mature trees, walls and landscaping on older downtown lots
- Interior drain pipe that needs replacing too
- Permit and inspection through SAFEbuilt's Community Core system (permit technician 970-545-3512; inspections 303-774-0454)
The Town asks residents not to flush wipes, even ones labeled flushable, and not to pour grease down drains. That's worth taking to heart after a replacement, because a new line can still clog. Older homes near downtown are the likeliest to have clay or cast iron pipe worn along its length; newer homes usually have plastic pipe that fails in one place.
