Philadelphia operates one of the oldest combined sewer systems in the country, where stormwater and sanitary sewage share the same pipes. During heavy rain, the system becomes overwhelmed and sewage backs up into basement floor drains. Neighborhoods like Queen Village, Northern Liberties, and West Philadelphia see repeated basement flooding during summer storms when runoff exceeds system capacity. This is not a plumbing problem you can fix. It is an infrastructure problem that requires professional flooded basement water removal and antimicrobial treatment every time it happens.
