What is PSL:

A private sewer lateral (PSL) is the pipe that connects the plumbing in a home or business to the sanitary sewer main, usually located in the street. The PSL carries sewage from a building to a public sanitary sewer. It is the responsibility of the property owner to maintain the sewer lateral.
Old, cracked sewer laterals allow rainwater and groundwater to infiltrate the sewer system. Excess water in the system can overwhelm wastewater treatment facilities, causing untreated or partially treated sewage to be released into the Bay. Fixing damaged PSLs helps protect the Bay.
