Philadelphia Sewer Systems

[Irfan Raza]

This topic is more geared to cities with combined sewer systems.  Philadelphia still continues to use a combined systems in which plumbing wastewater and stormwater combines through the same system.  During intense rainstorms, I believe this is the reason we are experiencing backups in properties which we have changed both the trap and lateral (outside house connecting to the main).  Below is a link to Philadelphia Water Department's Basement Protection Program (BPP).  Has anyone else experienced the same issues?  Have any Philly BP members tried the BPP program and, if so, what are your experiences with the program?
