Lyons' Backflow Prevention and Cross-Connection Control Program covers all non-single-family connections and any home with an identified uncontrolled cross-connection, and commercial and multifamily preventers must be tested every year by a State-certified tester with results sent to Town Hall. For a test, a repair or a new device, call the number on this page to be connected with a local plumber in Lyons.

Backflow in Lyons
The Town of Lyons provides water and wastewater inside town limits, drawing from North St. Vrain Creek and treating it at a town plant. Its BPCCC program, adopted by Ordinance 1007 under Colorado Regulation 11.39, covers every non-single-family connection and any residential connection with an identified uncontrolled cross-connection. Under Lyons Municipal Code 13-6-60, commercial and multifamily preventers are tested every year by a State-certified tester, and passing results go to Town Hall by email, mail or drop-off. Missing results can bring penalties up to disconnection under LMC 13-6-100. The Utilities Director is at 303-823-6622 x42.
What to do now
- Know your category. Commercial and multifamily properties test yearly; homes only if a cross-connection is identified.
- Find the device. Clear access to it.
- Stop leaks. Close the supply valve if water is escaping.
- Book a State-certified tester.
- Send results. Get the passing report to Town Hall.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Relief valve discharging | Fouled check or pressure fluctuation |
| Device cracked after winter | Freeze with water inside |
| Failed annual test | Worn rubber parts or springs |
| Town notice about a home connection | An identified uncontrolled cross-connection |
What affects cost
- Number of preventers. Restaurants and multifamily buildings may have several.
- Repairs. Parts and a retest after a failure.
- Freeze damage. Replacement rather than rebuild.
- Permits. The Town contracts SAFEbuilt for all building department work, through the Community Core portal.
Lyons sits where North and South St. Vrain Creeks meet, ringed by red sandstone hills, and cold air settles along the creeks on winter nights. Businesses along the historic downtown and the music venues that fill up for festival season at Planet Bluegrass have the kinds of connections the program targets. For after-hours water emergencies, the Town lists 303-441-4444. SAFEbuilt's inspection request line is 303-774-0454.
Homeowners aren't in the annual program unless the Town finds an uncontrolled cross-connection, such as a sprinkler system or a hose-fed connection with no protection. If you get a notice, a plumber can add the right device and test it so the Town has a passing result. Keep the paperwork; it's your proof the issue was fixed.
