Collecting rainwater is legal in Wisconsin and Rock County sets no barrier to rain barrels. There is no state permit for a basic downspout rain barrel used for outdoor, non-potable purposes. Some cities add setup conditions.
Wisconsin has no statute or administrative rule making it illegal to capture rain falling on your own property, and Rock County imposes no county-level ban. Setting a rain barrel under a downspout for outdoor, non-potable use, watering gardens, irrigating your lawn, washing a car, is essentially unregulated and needs no state permit. Restrictions, where they exist, are municipal: some cities require that a system not connect to the public water supply, not feed water inside a building, not be used for drinking, and not use a buried tank. Because rainwater is untreated, it should never be used for drinking. Confirm any local plumbing or setup rules with your city.
No county penalty applies. Municipal plumbing or backflow rules govern connected systems; violations are handled by the local building or plumbing inspector.
