Public Works manages Laconia’s 17 sewer pump stations and approximately 67 miles of gravity main and 5 miles of forced main. Sewage is piped into the Winnipesaukee River Basin Program (WRBP) regional wastewater system for treatment.
In the event of a sewer emergency, a little trouble shooting can go a long way to quickly fix the problem. If you are not the building owner, inform the building owner/manager of the issue and work with the owner/manager to repair the problem.
If the clog is in the building (such as a toilet) or in the service line from the building, contact a plumber. If the problem is not due to the building's system, the plumber will contact Public Works to ensure that the City's system is functioning properly.
The City has agreements with the owners of some private sewer collection systems. Public Works will respond to emergencies on these lines and charge the system's owner for services rendered.
Sometimes a clogged sewer main will cause a manhole to overflow. Please notify us if you see this happen.
If the sewer emergency appears to be due to a clog in a publicly-owned main or a privately-owned main with a maintenance agreement, contact us. During normal business hours (Mon-Fri 7:30-3:30), call the Public Works at (603) 528-6379. After hours, contact the Laconia Police Department at (603) 524-5252.
