A sewer permit is $150, and is obtained from the sewer commission, which has its office at the Department of Public Works in town hall. If there is work to be done inside the home, that would require a permit from the building department, obtained by the homeowner’s plumber at the homeowner’s expense. The final hookup from the main line under the street to the house is at the homeowner’s expense.

Connecting to the sewer system is at the homeowner’s discretion. Houses are not required to be hooked up unless there is a problem with the septic system.
