Louisville runs its own water utility, and a leak in the buried line between the meter and your home is generally a private plumbing repair. The city's Building Safety Division inspects plumbing work, so a repair or replacement may need a permit. Call the number on this page to be connected with a local plumber in Louisville.
When you place the call
The call goes to an independent local plumber who covers Louisville; this site arranges the connection only. Expect questions about where the water is showing, whether the whole house lost pressure and how long it's been going on. The plumber will usually confirm with a meter test, then trace and listen along the line to pin down the leak before recommending a section repair or a new line.
Cost factors
- Run length and depth. More distance from the meter means more digging.
- Age of the home. Older lines near downtown may justify replacement; rebuilt homes usually need only a repair.
- What's on top. New landscaping, patios and driveways take careful restoration.
- Entry point. Basements, crawl spaces and slabs each change the approach.
- Permit and inspection. Building Safety handles plumbing permits and inspections.
Louisville conditions
The City of Louisville runs two water treatment plants, supplied from South Boulder Creek and the Colorado River basin. Few homes are on private wells, since the municipal system serves the city. The city's published pages don't spell out where its responsibility for the service line ends, so if water is surfacing at the meter, call Public Works at (303) 335-4608 first; after 3:30 p.m., the Operations Division on-call line is (303) 489-2301.
Louisville keeps an inventory of water service lines to confirm no customers are served by lead lines, and it asks customers whose line material is unknown to self-report it. Doing that before a repair can save a step later.
The housing here falls into two groups. Louisville is a former coal-mining town with a historic downtown, and homes around Main Street can have older service lines. Hundreds of homes were also rebuilt after the December 2021 Marshall Fire, and those newer lines are more likely to fail at a fitting or where construction settled the soil than to wear out. Plumbing permits and inspections come from the Building Safety Division at City Hall, 749 Main Street, (303) 335-4584.
Quick checklist
- Locate the main shutoff and make sure it closes.
- Note the wet area and when it first appeared.
- Shut off irrigation so it doesn't confuse the search.
- Know your service line material if you've reported it to the city.
