Roxborough homes and their sewer lines
Roxborough mixes older stone and brick homes near Ridge Avenue with large areas of mid-century housing. The City’s Rowhouse Manual lists Roxborough among the places with post-war townhouses (“Airlites,” “straight-throughs”): one-car garage at the lower level, elevated front yard and entry. In those houses the drain often leaves through the garage level, so the lateral may run under the driveway apron rather than a flat sidewalk.
Homes built from about 1945 to the early 1970s may have laterals of bituminous fiber (“Orangeburg”) pipe, which was widely used in that era. It can soften, flatten out of round and let roots in as it ages.
Common sewer problems we hear about in Roxborough
- Post-war laterals of Orangeburg or early clay pipe flattening or root-filled
- Laterals under driveways and garage aprons, which adds concrete restoration to the quote
- Hillside drainage pushing stormwater into older connections
- Mature street trees sending roots into joints
What to know before you fix it
Parts of northwest Philadelphia drain toward the Wissahickon Creek, which is served by separate storm sewers rather than the combined system. PWD’s sewer service area map shows which system your block is on. In separate areas, the house storm drain is a distinct line on the customer side. A camera inspection can confirm your pipe material before you choose between lining and replacement.
The rules are the same citywide
In every Philadelphia neighborhood, the owner is responsible for the house drain, curb trap, lateral and the connection to the sewer. A licensed plumber must do the work, and PWD can issue a Notice of Defect with a deadline to fix it. Eligible owners can spread the cost over 60 months at zero interest with the HELP loan.
