The Town of Erie runs the cross-connection control program for its water system, and commercial and multifamily projects need backflow device test reports before a certificate of occupancy; detailed residential rules weren't found. For a test, a repair or a new device, call the number on this page to be connected with a local plumber in Erie.
Erie's water and backflow setup
Erie owns its water system, which serves roughly 13,000 taps. Most of the supply is Colorado-Big Thompson water treated at the town's Lynn R. Morgan Water Treatment Facility and disinfected with chlorine. Because the town runs the system, the town runs the cross-connection program too.
What the fact sheet confirms is the commercial side: on commercial and multifamily projects, the town wants backflow prevention device test reports before it issues a certificate of occupancy. The pages reviewed did not describe residential testing requirements in detail, so if you're a homeowner with a sprinkler device, ask Erie's utility staff at 303-926-2700 whether yours needs a periodic test.
Permits run through the Erie Building Division on Holbrook Street (303-926-2780). The town requires permits for plumbing modifications, and its plumbing permit types include water line repair. Erie has grown quickly from its coal-mining Old Town on Briggs Street into large subdivisions on both sides of the Boulder-Weld line, and most of those newer homes came with in-ground irrigation.
Options when a device acts up
| Option | Best for | Trade-off |
|---|---|---|
| Clean and retest | Debris holding a check open | Quick, but won't fix worn parts |
| Rebuild | Worn rubber and springs | Keeps the body, needs a retest |
| Replace | Cracked body or discontinued model | More cost, longer life |
Signs you need help
- A commercial or multifamily project is nearing its certificate of occupancy
- Water leaks from the sprinkler device when zones run
- Pressure drops on irrigation after a winter
- The town has asked about protection on your service
- Visible frost damage on the device
Seasonal notes
Erie sits on open plains northeast of Boulder, and winter wind and cold hit exposed devices hard. Drain sprinkler devices in fall, keep them insulated, and check them in spring before running every zone. Project schedules matter too: a backflow test report is one of the last items before occupancy, so plan the test so a failure doesn't hold up the move-in.
Homeowners can make a visit go faster by noting the device's make and size, which are cast or printed on the body, and by knowing where the irrigation shutoff is. If the device is leaking while you wait, closing that valve stops the waste without affecting water inside the house.
