Tree roots get into sewers when a sewer pipe develops a crack or other damage and nutrients and moisture leak into the soil, attracting the roots.
Root penetration can be remedied by repairing the faulty sewer pipe and ridding the pipe of roots. The maintenance of private sewers is the responsibility of private property owners. The City will repair and clean out public sewer lines.
Property owners are responsible for maintaining and repairing sewer laterals.
