rights to sewer main going through neighbors property

[Brian Christensen]

Hi,

I have a rental in which the sewer main runs through the neighbors property to the street. The main was crushed per the line camera and the section is on their property, likely their front yard. I cannot get a hold of the owner to start the repairs, even though the property manager has left notes on their door. I am unable to get any info on the county record. The main still works, but could fail anytime per the plumbers. Anyone familiar with what are my rights or recourses are in this situation? I assume I need their approval. I need to get it fixed asap. Have tried for 3 days to reach him. Any advice is appreciated.

Thanks, Brian
