Full Breakdown
Utah controls rainwater harvesting at the state level through Utah Code 73-3-1.5, so the rules are the same everywhere in Davis County. Without any registration you may collect precipitation in no more than two covered containers, each holding no more than 100 gallons (200 gallons total). To store more, up to a total of 2,500 gallons, you must register the collection for free with the Utah Division of Water Rights through its online portal. In every case the captured water must be put to beneficial use on the same parcel where it was collected; you cannot pipe it off-site or share it with a neighbor's lot.
