Philadelphia actively promotes rainwater harvesting through the Green City, Clean Waters program and the PWD Rain Check program. Free 55-gallon rain barrels are available to residents. The city's stormwater regulations under Phila. Code §14-704(3) encourage green infrastructure including rain gardens and rainwater collection for non-potable uses.
Rainwater harvesting in Philadelphia is generally permitted for residential use including garden irrigation, lawn watering, and non-potable household purposes. Pennsylvania does not impose significant state-level restrictions on residential collection. Rain barrels and cisterns may be installed without special permits in most cases, though large systems may trigger building or plumbing permits. HOAs may have restrictions on visible rain barrel placement. Potable use of collected rainwater requires treatment systems that meet health department standards. Some cities offer rain barrel rebate programs.
No penalties for standard residential collection. Large cistern installations without building permit: standard building code violation $100 to $500.
