Plumbing services in Evergreen
An unincorporated mountain community
Evergreen has no city government. It is an unincorporated community and census-designated place in Jefferson County, with 9,307 residents in the 2020 count. Its center is about 21 miles from downtown Denver in a straight line, and Golden is the nearest larger city. The town grew up around Evergreen Lake and Bear Creek, with Bergen Park and Hiwan to the north, Kittredge nearby, and State Highway 74, County Highway 73 and I-70 as the main roads.
District water from Evergreen Lake
Inside its boundaries, the Evergreen Metropolitan District supplies surface water from Evergreen Lake, treated at the district's membrane filtration plant and disinfected with chlorine. The district describes the water as slightly hard, typically about 30 mg/L, says a softener is not needed, and adds a poly-ortho-phosphate blend for corrosion control. Its consumer confidence report has the annual results, and it keeps a service line inventory you can ask about. The district site also refers to West Jefferson County Metro District and Kittredge Sanitation and Water District, so confirm your provider by address.
The district handles sewer mains for its customers as well. Homeowners are responsible for maintaining and repairing their water and sewer service lines from the district main, usually in the street, to the house. For a sewer backup or a broken water line, the district tells customers to shut off water at the home's valve and call both a plumber and the district at 303-674-4112 (option 2 during business hours, option 9 after hours).
Wells and onsite systems outside the district
Jefferson County says water in the mountain areas is generally supplied by wells, and many homes outside the district are not on municipal sewer and use a private onsite wastewater system instead. The County notes that radon occurs naturally in many of its ground water supplies and recommends that owners test private wells. For a well home, a no-water call can mean a pump, pressure tank or control problem rather than a pipe leak, and that is worth mentioning when you call.
Backflow and permits
The district's cross-connection program covers commercial, industrial, multifamily and some single-family properties. Assemblies are tested every year, and irrigation assemblies must be tested within seven days of being turned on. You can hire any testing company, and reports are filed through The Compliance Engine. Plumbing permits, including water heater permits, come from Jefferson County Building Safety, which takes applications online (303-271-8260).
Gas and propane
If you smell gas, leave the house first. From outside, call 911 and your gas utility, whose name and emergency number are on your gas bill. If your home runs on propane, call 911 and your propane supplier.
Evergreen versus Denver
Denver homes sit on Denver Water and city sewer, with Denver issuing permits. In Evergreen you may be on district water or a private well, district sewer or an onsite system, and the permit comes from the County. Altitude cold also hits harder than in the city. When you call the number on this page, say whether you are on district water or a well, and whether the water is off. You will be connected with an independent plumber who works in Evergreen, and you agree on price and timing with that plumber.
