Evergreen Metropolitan District requires backflow assemblies on commercial, industrial, multifamily and some single-family properties to be tested every year, and irrigation assemblies must be tested within seven days of being turned on, with reports filed through The Compliance Engine. For a test, repair or new assembly, call the number on this page to be connected with a local plumber in Evergreen.

What happens when you call
You'll be connected with an independent plumber who serves Evergreen. First, confirm you're on Evergreen Metropolitan District water; many homes outside the district rely on private wells. Then say what the device protects and whether you're working against the seven-day window after turning on irrigation. The district lets customers choose any testing company, so ask the plumber whether they'll file the report through The Compliance Engine.
What affects the cost
- Timing. A test tied to spring irrigation start-up is routine; a rush after a missed window may not be.
- Repairs. Failed checks or relief valves need parts and a retest.
- Freeze damage. Mountain winters crack devices left full of water.
- Access on steep lots. Devices on hillsides or in rock-walled enclosures take longer.
- Permits. New work goes through Jefferson County Building Safety.
Evergreen's water and backflow rules
Evergreen is unincorporated, centered on Evergreen Lake and Bear Creek, with Bergen Park and Hiwan to the north. Evergreen Metropolitan District serves homes inside its boundaries, and the district site also references West Jefferson County Metro District and Kittredge Sanitation and Water District. Jefferson County says mountain-area water is generally supplied by wells, so many Evergreen homes outside district lines aren't covered by any utility program.
Inside the district, the cross-connection program requires assemblies on commercial, industrial, multifamily and some single-family properties, tested annually and maintained. The irrigation rule is distinctive: test within seven days of turning the system on. All reports go through The Compliance Engine. Evergreen sits high enough that freezing nights linger well into spring, so a device that wintered full of water often fails that first test. The district's water is only slightly hard, typically about 30 mg/L, so scale is less of an issue than freeze damage.
The district also has standards for service line repairs, and contractors digging within 10 feet of district infrastructure have to meet its requirements. If a backflow job turns into line work near the street, ask the plumber how they'll handle that.
Before the visit
- Confirm you're inside Evergreen Metropolitan District
- Note the date you turned irrigation on
- Clear snow, rocks or brush around the device
- Know where the main shutoff is
- If on a well, mention it; protection still matters for your supply
