The Town of Lyons provides water to homes and businesses within town limits, treating North St. Vrain Creek water at its own plant, so town homes don't have well pumps. Service for 80540 properties outside town limits wasn't verified, and where those properties run private wells, a plumber can test the pump, switch and tank. Call the number on this page to be connected with a local plumber in Lyons.

Water in Lyons
Lyons sits where North and South St. Vrain Creeks meet, ringed by red sandstone hills on US 36 and SH 7. The Town diverts North St. Vrain Creek at an intake about half a mile upstream of its treatment plant, and also holds Colorado-Big Thompson shares delivered through the St. Vrain Canal, with storage in Button Rock Reservoir. Inside town limits, that's the water supply, and homes on it have no pump of their own. The Town also runs its own wastewater plant and maintains its sewer mains; the line from your property to the Town main is yours.
Outside town limits, the 80540 ZIP covers foothills land where water service wasn't verified. If your property there has a capped wellhead and a pressure tank, you own a private well system.
What to do when water stops
- Decide which system you're on: Town water or a private well.
- For Town water, check with neighbors and call Utility Billing at 303-823-6622 ext. 10, or 303-441-4444 after hours.
- For a well, check the pump breaker and tank gauge, and leave a re-tripping breaker off.
- Look for frozen pipes along exterior walls and in crawl spaces on cold mornings.
- Shut the main if a pipe is leaking.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| No water on Town service | Town outage, frozen line or closed valve |
| No water on a well | Pump, switch, breaker or control box |
| Weak pressure in town | Regulator or a leak on your line |
| Well switch clicking fast | Pressure tank lost its air charge |
| Well pump never stops | Leak, worn pump or failed switch |
What affects the cost
- Town-water plumbing repairs versus well equipment
- For wells: the failed part, pump depth and tank condition
- Access on sloped foothills lots
- Thawing and repairing frozen pipes
- Permits: SAFEbuilt runs the Town's building department through its Community Core system, and inspections are booked at 303-774-0454
Boulder County has no building code jurisdiction inside the town, so town addresses go to the Town's building department, at Town Hall, 432 5th Avenue.
Commercial and multi-family water connections in Lyons with backflow preventers need an annual test by a State-certified tester. If you own one of those properties, the plumber can help coordinate the test while on site.
