Intense rainfall has increased in the Philadelphia region, and with climate change, scientists predict it will worsen over time.
Rain forecasts not only threaten the region with flooding. Storms put waterways at risk of increased pollution that washes off streets and buildings, as well as sewage overflows.
Older cities like Philadelphia and Camden have outdated sewer systems that accept stormwater and raw sewage in the same pipes. During heavy rains, these systems often overflow — spilling stormwater runoff and sewage into rivers and streams.
