Lyons is a small foothills town where North and South St. Vrain creeks meet, and the Town of Lyons runs both water and wastewater for homes and businesses inside town limits. Drinking water comes from North St. Vrain Creek and is treated at a town plant, and the town operates its own wastewater treatment plant and sewer mains. Properties with a Lyons (80540) address outside town limits were not covered by our research, so check your bill.
What to do in the first minutes
- Close the main valve where the water line comes into the house.
- Report town-side trouble. Utility Billing answers at 303-823-6622, extension 10, during business hours; after hours and for emergencies the town lists 303-441-4444.
- Shut off a leaking water heater at its cold inlet and its gas control or breaker.
- Stop running water if drains are backing up.
- Smell gas? Get out. Call 911 and Xcel Energy from outside.
- Photograph the damage before cleanup.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Floor drain filling with wastewater | Blockage in the owner's sewer line, often wipes or grease |
| Ceiling drip under a bathroom | Failed supply line, drain joint or toilet seal |
| Water pooling at the water heater | Tank failure or loose connection |
| No water on a frigid morning | Frozen supply line in a crawl space or exterior wall |
| Water in the street or near the curb | Town main or service connection; call the town |
Cost factors
Night, weekend and holiday calls usually cost more, and Lyons sits about 36 miles from downtown Denver, so travel can add to it. Access is the next factor, especially in older homes with tight crawl spaces. The scope matters too. On the sewer side, Lyons makes residents and business owners responsible for the line running from their property to the town main, while the town maintains its mains; the town specifically asks people not to flush wipes, even ones labeled flushable, or pour grease down drains, both common causes of backups. The sheet we use does not say where the town's part of the water service line ends, so ask the town about any leak near the street. Building permits in Lyons are handled entirely by SAFEbuilt under contract with the town, through its Community Core portal; Boulder County has no building code jurisdiction inside town limits. When you call, have the address ready and say whether the main is off. No arrival time is promised.
