Lafayette runs its own water and wastewater utility through Public Works, and the meter pit marks the line: the city owns the pipe from the main to the pit, and the homeowner owns everything from the pit to the house. Plumber Denver CO is a free referral line, not a plumbing company; call the number on this page to be connected with a local plumber in Lafayette.
Plumbing services in Lafayette
Southeastern Boulder County
Lafayette is a home rule city in southeastern Boulder County, about 19 miles from downtown Denver in a straight line and its nearest larger city is Boulder. It grew out of coal mining and farming, and the 2020 Census counted 30,411 residents. Old Town and Festival Plaza sit along Public Road, US 287 is the main corridor, and CO-7, CO-42 and the Northwest Parkway connect it to neighbors. Waneka Lake Park and the Waneka Granary are local landmarks.
Reservoir water from city intakes
Lafayette's Public Works Department supplies treated water to about 10,000 properties. The water comes from four city intakes at Baseline Reservoir, Waneka Reservoir and Goose Haven reservoirs No. 1 and No. 2, and the city's water rights include Colorado-Big Thompson Project shares and Windy Gap water from the Colorado River. Chlorine is the disinfectant measured in the distribution system. The city's report does not list a hardness figure.
The city keeps a service line material inventory covering both city-owned and customer-owned portions, built from records, resident surveys and potholing, and it notifies owners if a lead or galvanized line needs replacement. Questions go to LCRR@lafayetteco.gov or 303-661-1277.
Wastewater stays local
Sewage is treated at the city-run Lafayette Water Reclamation Facility, designed for up to 4.4 million gallons a day, which releases treated water to Coal Creek. For water main breaks or sewer backups on weekends or after hours, the city directs residents to Boulder County Dispatch at 303-441-4444; during business hours, Public Works answers at 303-661-1277.
Backflow deadlines
Lafayette's backflow program runs through BSI Online. Commercial accounts and residential accounts other than single-family homes must have each assembly tested yearly by an ABPA- or ASSE-certified tester. Irrigation assemblies are due by May 31, and domestic containment and fire assemblies by August 31. A failed test must be reported within 24 hours and the assembly fixed and retested within five days, and missed deadlines can lead to a water shutoff.
Permits and gas
The Planning and Building Department's Building Division issues building permits; the inspection line is 303-604-3822, and City Hall at 1290 S. Public Road has a permit drop-off box. Ask the division which plumbing jobs need a permit before replacing a water heater. No gas utility for Lafayette was confirmed, so check your gas bill for the name and emergency number. If you smell gas, leave first, then call 911 and your gas utility from outside.
How it differs from Denver
Denver relies on Denver Water and regional treatment at Metro Water Recovery. Lafayette has its own reservoirs, plant and reclamation facility, and its after-hours calls go through county dispatch. No housing-age figure for Lafayette was confirmed. Call the number here and you will be connected with an independent plumber serving Lafayette who quotes the job directly.
