Rainwater harvesting is legal and encouraged in Minnesota. Neither Anoka County nor the state restricts residential rain barrels or cisterns; state and metro agencies actively promote them for stormwater and conservation.
Minnesota does not limit a homeowner's right to collect rooftop rainwater, and Anoka County sets no rule against rain barrels or cisterns. State agencies encourage the practice: the Board of Water and Soil Resources, Metropolitan Council, and local watershed districts run rebates and workshops on rain barrels and rain gardens to reduce runoff and municipal-water use. Harvested rain is typically used for lawns, gardens, and other non-potable outdoor purposes. If you plan a large cistern or a system plumbed into the house, standard state plumbing-code and permit rules may apply, and any connection to potable plumbing needs backflow protection. Overflow should be directed away from neighboring lots and the public right-of-way.
No penalty exists for ordinary rain-barrel use. Improper cross-connection to drinking-water plumbing, or overflow flooding a neighbor, could trigger plumbing-code or nuisance enforcement.
