If you are on Evergreen Metropolitan District water, the district describes it as only slightly hard, typically about 30 mg/L, and says a softener is not needed. Homes outside the district usually rely on private wells, and those deserve a full water test before any equipment is chosen. Call the number on this page to be connected with a local plumber in Evergreen.

What happens when you call
The call connects you with an independent plumber who works in Evergreen. The first question is where your water comes from: Evergreen Metropolitan District or a private well. For district homes, expect an honest conversation about whether you need anything at all. For well homes, expect the plumber to talk about testing, where the pressure tank and well line enter, and how any treatment equipment would be laid out between the well and the house.
What affects the cost
- District water versus a private well
- Lab testing of well water before equipment is chosen
- Filters for iron, manganese or sediment, if a well test calls for them
- Where treatment discharge goes on a home not on municipal sewer
- Space near the pressure tank or main in a mountain-home crawl space
- Jefferson County permit requirements
Evergreen's two water situations
Evergreen Metropolitan District takes surface water from Evergreen Lake, treats it at its membrane filtration plant, and disinfects with chlorine. The 2026 report lists no violations. The district's water FAQ describes the water as slightly hard, from 17.1 to 60 mg/L and typically around 30, and says a softener is not needed. The district also adds poly-ortho-phosphate for corrosion control. For district customers, a softener is usually money spent on a problem you do not have.
Outside the district, things change. Jefferson County says mountain-area water is generally supplied by private wells, and many homes are also not on municipal sewer, relying on private onsite wastewater systems instead. Well water varies from one property to the next. The county notes that radon occurs naturally in many county groundwater supplies and recommends that homeowners test private wells. A test for hardness, iron, manganese, radon and bacteria gives you the full picture before you buy anything.
If a well home does need a softener, the regeneration brine has to go somewhere. On a home not on municipal sewer, that discharge goes into the private onsite system, so the plumber should talk through drain routing and an efficient, demand-based valve that keeps the volume down.
Checklist before the plumber arrives
- Know whether you are a district customer or on a well
- Gather any past well test results
- Note staining, odor, scale or taste changes
- Find the main shutoff or pressure tank
- Clear access to the crawl space or utility room
