Stormwater Management
Many neighborhoods of Philadelphia have a
combined storm water and waste water sewer
system. In heavy rainfalls, the volume of water
exceeds the capacity of the system and untreated
waste water flows into the city’s waterways. PHS,
in partnership with the Philadelphia Water
Department, has received a grant from the
Pennsylvania Department of Environmental
Protection to create a pilot program to determine
how vacant land can be used to retain water
during excessive rain events.
In the past two years, five sites have been created
using various techniques of grading to investigate
efficient systems of storm water management.
