Rain barrels and cisterns for landscape irrigation are legal and encouraged in Manatee County; SWFWMD and county utilities promote them for conservation. No county permit is needed for typical residential rain barrels; large cisterns follow the Florida Building Code and plumbing rules.
Florida does not restrict residential rainwater collection, and Manatee County/SWFWMD actively encourage rain barrels and cisterns to reduce potable-water use for irrigation. Small residential rain barrels connected to downspouts need no county permit. Harvested rainwater used for lawn/landscape irrigation is not subject to SWFWMD day-of-week watering restrictions, making it a practical workaround during shortages. Larger cisterns, buried tanks, or any system cross-connected to household plumbing must comply with the Florida Building Code and require plumbing permits to prevent backflow into potable supply. Systems should be screened/covered to avoid mosquito breeding.
No penalty for compliant residential rain barrels. Improper cross-connection to potable plumbing, or an unpermitted large cistern, is a building/plumbing code violation.
