Inside Evergreen Metropolitan District, commercial, industrial and multifamily properties must test their backflow assemblies every year, and irrigation assemblies within seven days of being turned on. Outside the district, mountain properties generally rely on wells and many aren't on municipal sewer. Call the number on this page to be connected with a local plumber in Evergreen.

How a call works
You'll be connected with an independent local plumber who takes commercial jobs in the Evergreen area. Start by saying whether the property is on Evergreen Metropolitan District water and sewer or on its own well and onsite system, since that shapes the whole job. Then describe the business, what's failing and whether water is off. Mountain roads and weather can affect scheduling, so mention any deadline or event you're working around.
If the job involves a water heater or other plumbing changes, the plumber will likely mention a permit. Evergreen is unincorporated, so permits come from Jefferson County Building Safety, which takes plumbing permit applications online, including for water heaters.
What affects the cost
- Whether the building is on district service or a private well and onsite wastewater system
- Excavating a service line, which must follow district standards near district pipes
- Backflow assemblies that need repair before passing
- Travel and access on steep or snowy sites
- County permits and off-hours scheduling
Evergreen's water and sewer
Evergreen Metropolitan District draws surface water from Evergreen Lake and treats it with membrane filtration and chlorine, adding a corrosion control treatment. The district calls the water slightly hard, typically about 30 mg/L, and says a softener isn't needed. It also handles sewer mains for its customers. Owners are responsible for maintaining and repairing their water and sewer service lines from the district's mains, usually in the street, to the building. Contractors digging within 10 feet of district pipes have to meet the district's contractor requirements, and service line repairs must follow its standards.
For a sewer backup or burst line, the district asks customers to shut the building's valve, then call a plumber and the district at 303-674-4112, option 2 during business hours or option 9 after hours.
The district's cross-connection program covers commercial, industrial, multifamily and some single-family properties. Assemblies must be installed, tested every year and maintained, and irrigation assemblies must be tested within seven days of being turned on in spring. Owners can choose any testing company, and every report goes through The Compliance Engine.
Outside the district, Jefferson County says mountain-area water generally comes from wells, and many properties use a private onsite wastewater system rather than municipal sewer. The county also notes that radon occurs naturally in many groundwater supplies and recommends testing wells. The gas utility wasn't confirmed for Evergreen; if a building runs on propane, its supplier is the emergency contact.
