Lyons basics
Lyons sits where North and South St. Vrain Creeks meet, ringed by red sandstone hills. The town draws water from North St. Vrain Creek at an intake about half a mile above its treatment plant and also holds Colorado-Big Thompson shares and storage in Button Rock Reservoir. It serves residents and businesses inside town limits with water and sewer, runs its own wastewater plant and maintains the town sewer mains. Owners are responsible for the sewer line from their property to the main, and the town asks people not to flush wipes, even flushable ones, or pour grease down drains. Gas is Xcel Energy.
Steps to take first
- Shut off the fixture, or close the building's main if water is spreading.
- Stop using any drain that's backing up.
- For a town water or sewer emergency after hours, call 303-441-4444; during the day, Utility Billing is 303-823-6622, extension 10.
- If anyone smells gas, get everyone out, then call 911 and Xcel Energy at 1-800-895-2999 from outside.
- Photograph damage and note the time.
- Call the number on this page for a plumber on the private side.
Symptoms and causes
| Symptom | Likely cause |
|---|---|
| Kitchen drains slowing during busy weekends | Grease building up in the line |
| Restroom backups after an event | Wipes or paper products in the owner's sewer line |
| Backflow preventer leaking at its relief port | Worn internal parts that may fail testing |
| No water after a cold night | Frozen piping in an exterior wall or unheated room |
| Hot water running short | A heater undersized for peak demand |
Cost factors
Fixture count, building size and access set most of the price. Lyons' Backflow Prevention and Cross-Connection Control Program, adopted by ordinance under Colorado Regulation 11.39, covers every connection that isn't a single-family home plus homes with an identified cross-connection. Commercial and multifamily preventers must be tested every year by a state-certified tester, with passing results sent to Town Hall by email, mail or drop-off, and missing results can bring penalties up to disconnection, so a failing device needs quick repair. Program questions go to the Utilities Director at 303-823-6622, extension 42. The town contracts its building department to SAFEbuilt, with permits through the Community Core portal and inspections at 303-774-0454; Boulder County has no building code authority inside town. Grease-related sewer repairs, after-hours work and digging on the owner's line also add up.
