Water Line Repair in Boulder, CO

Clues that the service line has failed

• Wet or sunken ground between the street and your house
• Low pressure that hits every faucet, shower and appliance together
• Water seeping in where the line enters the basement or crawl space
• A city utility bill that rose without explanation
• The sound of running water when nothing is on

How Boulder handles service lines

The City of Boulder runs its own water system, supplied from Barker Reservoir, North Boulder Creek, Carter Lake and Boulder Reservoir depending on the season. City code makes every water customer responsible for the upkeep of the area between the meter pit and the street. The city's page doesn't spell out who owns the meter and curb stop, and it says only city personnel may open meter pits. So don't lift the lid yourself. If you need water shut off in an emergency after hours, call the city at 303-441-3200.

On materials, the city's service line inventory found no lead service lines in the system. Boulder still encourages owners of homes built before 1956 to verify their pipe material on the city's online service line map, and that's worth doing before planning a replacement on an older house near downtown, Chautauqua or the University Hill area. Older galvanized or patched lines are more likely to fail along their length than a newer line, which usually fails at a fitting or where it was struck by digging.

Boulder's permit rules draw a clear distinction. Repairing a leak counts as minor work and is exempt, but replacing concealed supply piping is treated as new work and needs a single-trade plumbing permit from Planning and Development Services at 1101 Arapahoe Avenue.

What changes the price

• Repair versus replacement. A leak repair is exempt from permits; a replacement is not.
• Length and route. Deep setbacks, slopes and rock add excavation time.
• Surface restoration. Flagstone walks, xeriscaping and mature trees take careful work.
• Entry into the house. Basements, slabs and crawl spaces each need a different approach.
• Coordination with the city. If the meter pit needs opening, city staff have to be involved.

What the call looks like

This line connects you with an independent local plumber serving Boulder; the site doesn't do plumbing work itself. Describe where the water is showing and how long it's been there. If it's flowing heavily, close the main shutoff inside the house. The plumber will confirm the leak, trace the line and walk through whether a repair or a new line is the better choice.
