South Philadelphia homes and their sewer lines

South Philadelphia is classic rowhouse Philadelphia. Most homes are attached two-story brick rows with a basement, built close to the sidewalk. In a typical rowhome the house main drain leaves through the front basement wall, passes the curb trap and vent, then runs as the lateral under the sidewalk to the sewer main in the street. You almost never have a side yard to dig in.

Most of South Philly lies inside the city’s older combined sewer area, where one pipe carries both sewage and stormwater. Combined sewers serve about 60% of Philadelphia. During very heavy rain those mains can surcharge, which is one reason PWD runs its free backwater-valve program.

Common sewer problems we hear about in South Philadelphia

  • Curb trap clogs and broken vent (fresh air inlet) covers at the front of the house
  • Cracked or separated laterals under the sidewalk, sometimes noticed as a sunken pavement square
  • Rain-related backups through the basement floor drain on low-lying blocks
  • Shared-wall concerns: your plumber has to protect the neighbors’ front steps and party walls

What to know before you fix it

Because the lateral usually runs under the sidewalk, expect a Streets Department footway permit (issued with the L&I Plumbing Permit) and concrete restoration in the quote. Opening the street adds lane-closure permits, and that matters on narrow one-way blocks where parking is tight. When the pipe qualifies, trenchless lining can avoid breaking up marble or concrete front steps.

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.
