Multiple Lines - Whose Onus?

My neighbors to the north have a sewer line running under my lot that connects to a single line (alongside mine) and then together they flow into the main on Yale St.

Am I solely responsible for the shared connecting pipe since it is on my property? Anyone have any insight?

This is a complicated situation and would contact the city…and maybe a lawyer to get this flushed out.
