Welcome to The LWSC Sewer Department

LWSC is responsible for both collection and treatment of wastewater. The Sewer Department is responsible for the maintenance and functional operation of the sewage collection. The Sewer Department can assist homeowners if problems such as back-ups occur, however, please keep in mind that the homeowner is responsible for the sewer service line from the home all the way to the main in the street. The Sewer Department, in corporation with the Engineering Department, will work with homeowners and contractors to provide utility information and issue permits for sewer repair work.

The collection system carries the wastewater flow to the Lynn Regional Wastewater Treatment Plant, located on 2 Circle Ave. This large and impressive facility treats flows from the surrounding areas of Saugus, Swampscott, and Nahant. For more information on the Wastewater Treatment Plant, including its treatment processes, please see “Wastewater Treatment” under “About LWSC”.

When making repairs to your sewer service line, is it LWSC policy that the drainlayer/contractor performing the work is currently active with LWSC. See the Active Drainlayer list for the updated list of contractors/ drainlayers who are licensed to perform water and sewer work with LWSC.

Some History

Wastewater collection began in Lynn in 1866 with the construction of a stone and brick sewer in Union street. By 1879, the Lynn City Engineer reported that all but 7.5 miles of major streets had been sewered. In the 1880's and early 1890's, many of the larger sewer mains were constructed including the Eastern and Western Interceptors along with several of the submains. During that decade, the number of connections rose from 1,005 to 1,988. The system has continued to expand and there are 140 miles of pipe.

The Eastern interceptor is approximately 1,000 feet long and ranges in size from 40 inches by 54 inches to 64 inches by 72 inches. It is an egg shaped brick sewer constructed in 1885-1887. The Eastern Interceptor has not needed major renovation. A section of the interceptor was built in 1979 when the primary treatment plant was being built.

The Western interceptor is approximately 10,400 feet long and ranges in size from 36 inches in diameter to 54 inches by 72 inches. It is egg shaped in some sections and circular in others, and was constructed in 1890-1891.
