Who is responsible for which part

In unincorporated Los Angeles County the public sewers are maintained by the County's sewer maintenance districts, run by Los Angeles County Public Works, and the lateral is the owner's from the house to the main. Public Works says it plainly: "Homeowners are required to maintain the sewer line (also known as lateral) from their home to the main sewer line, typically located in the street or nearby easement." County Code section 20.24.080 provides that all house laterals "shall be maintained by the owner of the property served in a safe and sanitary condition".
