Water Softener in Lafayette, CO

Lafayette draws surface water from its own reservoirs and treats it at a city plant, and its 2026 report does not state hardness. That leaves a tap test as the starting point for any softener decision. Call the number on this page to be connected with a local plumber in Lafayette.

About Lafayette water

Lafayette Public Works provides treated water to about 10,000 properties. The city takes surface water from four intakes: Baseline Reservoir, Waneka Reservoir and Goose Haven Reservoirs No. 1 and No. 2. Its water rights include Colorado-Big Thompson Project shares and Windy Gap water from the Colorado River. Chlorine is the disinfectant in the distribution system. The 2026 report, covering 2025, does not give a hardness figure, so there is no published number to compare your fixtures against.

The meter pit marks the line of responsibility. The city owns the service line from the main to the meter pit, and the homeowner owns everything from the pit to the house, including any treatment equipment. If a softener install uncovers a leak or a corroded fitting on that stretch, the repair is the owner's. Lafayette grew out of a coal-mining and farming past, and Old Town homes near Public Road can have older plumbing than the subdivisions along US-287, so it is worth asking the plumber to look over the line while the water is off.

Steps to take first

Note what you see: white crust, spotting, a chlorine smell or something else.
Check the city's latest water quality report, or call Public Works, for any hardness information.
Have a plumber test hardness at your kitchen tap. That number drives every decision after it.
If taste is the issue, ask about a carbon filter; chlorine responds well to plain carbon.
Pick an install spot near the main with a drain and an outlet, ideally inside heated space.
Ask the plumber to confirm permit needs with Lafayette's Building Division.

Water Softeners & Filtration questions in Lafayette

Does my water provider publish a hardness number?

Not in the 2026 report we reviewed. Lafayette's report covers its reservoir sources and chlorine disinfection but gives no hardness figure, so a tap test is the best guide.

Will a softener get rid of chlorine or chloramine taste?

No. Lafayette uses chlorine, which an ordinary carbon filter reduces well. A softener only exchanges minerals.

Is a reverse osmosis unit at the kitchen sink worth adding?

If you want very low-mineral drinking water, yes. For simple chlorine taste in Lafayette, a carbon filter usually does the job for less.

How much upkeep does a softener need?

Top up salt every month or two, check for salt bridges, and have the valve serviced every few years. Carbon filters need media or cartridge changes.
