Rainwater harvesting is legal and actively encouraged in Prince George's County. Rain barrels and cisterns are Rain Check-approved practices eligible for county rebates, and Maryland counts rainwater harvesting as an accepted Environmental Site Design (ESD) stormwater practice.
Prince George's County places no prohibition on collecting rooftop rainwater, and rain barrels and cisterns are recognized practices under the County's Rain Check Rebate Program, administered with the Chesapeake Bay Trust. Property owners, businesses and nonprofits can recover part of the cost of rain barrels, cisterns, rain gardens, green roofs or conservation landscaping. A rain barrel project needs no pre-approval. The Maryland Department of the Environment promotes rainwater harvesting as a conservation practice that captures rooftop runoff, reduces Chesapeake Bay pollution, and earns stormwater credit as an Environmental Site Design measure. Maryland guidance limits harvested rainwater to non-potable uses. Larger cisterns plumbed indoors may require DPIE permits and backflow protection, but a downspout rain barrel needs no approval.
There is generally no violation for using a rain barrel or cistern outdoors. Larger harvesting systems connected to indoor plumbing must meet Maryland plumbing and backflow-prevention rules and may require DPIE permits and WSSC cross-connection protection.
