Overview

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.

Sewer Emergencies:

In the event of a sewer emergency, a little trouble shooting can go a long way to quickly fixing the problem.  if you are not the building owner, inform the building owner/manager of the problem and work the owner/manager to fix 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.
