Rainwater harvesting is legal in Chester County and across Pennsylvania. The state DEP has no permit program for private rain barrels or cisterns used for non-potable uses like watering gardens.
Pennsylvania does not prohibit rainwater collection, and Chester County has no rule against it. The PA Department of Environmental Protection has no permitting program for private residential rainwater-harvesting systems, and using stored rainwater for non-potable tasks such as watering a garden, washing a car, or flushing toilets is unregulated. Chester County actively encourages rain barrels through Conservation District and Water Resources stormwater/Chesapeake Bay programs. Two caveats: potable (drinking) use requires DEP-level treatment and approval, and a plumbing permit may apply if you tie a cistern into household plumbing. Check your municipality for any local plumbing-code requirements.
No penalty for ordinary rain-barrel use. Cross-connecting an untreated cistern to potable household plumbing without approval can violate the state plumbing code and utility rules.
