What is a sewer lateral (service) and for what portion am I responsible?
The contractor installing the sewer main generally installs the sewer service from the main to the property line. WSSC is responsible for maintaining the individual sewer service (lateral) from the main to the property line. Service lines (laterals) are generally 4″ for private homes. The service line from the property line to the house and sewer pipes within the house is the responsibility of the homeowner.
