Howard County does not ban rainwater harvesting. Rain barrels and cisterns are legal and actively promoted through the county's Live Green Howard and stormwater programs, which offer credits and guidance for capturing roof runoff to reduce stormwater and Chesapeake Bay pollution.
Maryland has no statewide prohibition on collecting rainwater, and Howard County treats harvesting as a stormwater best-management practice rather than something to restrict. Through the Live Green Howard initiative and the county's stormwater-management and watershed-protection programs, residents are encouraged to install rain barrels, cisterns and rain gardens; property-tax or fee credits and rebates may apply for qualifying stormwater practices. Large cisterns tied to plumbing or used indoors must still meet the county plumbing and building codes. There is no county rule limiting how much roof water a homeowner may capture for outdoor use.
No penalties exist for ordinary rain-barrel use. Cisterns connected to household plumbing must meet the adopted building and plumbing codes and any required permits.
