Sewer Line Repair in Philadelphia, PA

Sewer Line Repair in PhiladelphiaSewer lateral repair in Philadelphia is the homeowner’s responsibility, and old clay and cast iron laterals under row house sidewalks crack, separate and fill with roots. Because laterals often run under the sidewalk and sometimes the street, accurate camera inspection and locating keep excavation small. Because the owner is responsible for the lateral, the Water Department’s loan program can also apply to eligible sewer lateral repairs.
