Rainwater harvesting is legal in Prince William County and, as a riparian state, Virginia places no ownership limit on captured rain. Rain barrels are unregulated; larger cisterns or systems plumbed for indoor use must meet the Virginia building code and county permitting.
Virginia does not restrict rooftop rainwater collection, so residents may install rain barrels freely to water gardens and lawns. Simple barrels need no county permit. Larger cisterns, underground storage, or systems connected to indoor plumbing or irrigation lines fall under the Virginia Uniform Statewide Building Code and require plumbing/building permits and backflow protection through the county's Building Development Division. Harvested rainwater is also encouraged as a stormwater-management and Chesapeake Bay water-quality practice.
No penalty for ordinary rain barrels. Installing a plumbed cistern or irrigation-connected system without the required building/plumbing permit is a building-code violation subject to stop-work orders and permit-correction fees.
