Wisconsin allows residential rainwater harvesting without state restriction. Madison, Sun Prairie, Fitchburg, Middleton, and other Dane County cities actively encourage rain barrels through rebate programs. MMSD (Madison Metro Sewer) offers subsidies. Large cisterns may need SPS 382 plumbing review.
Wisconsin has no statewide restriction on residential rainwater collection; DSPS supports harvesting under Wis. Admin. Code SPS 382 (plumbing). Madison's Engineering Division and the Wisconsin Department of Natural Resources actively promote rain gardens and rain barrels to reduce runoff into the Yahara lakes (Lake Mendota, Monona, Waubesa, Kegonsa). The Madison Water Utility and nonprofit Clean Lakes Alliance have offered rebates historically. Rain barrels under 100 gallons require no permit in most jurisdictions. Cisterns over 600 gallons or those connected to indoor plumbing require review under SPS 382, and potable-use systems must include backflow prevention, filtration, and disinfection. Homeowner associations cannot prohibit rain barrels under Wis. Stat. §236.293 (HOA limitation for drought-tolerant landscaping), though they may impose reasonable aesthetic screening. Dane County stormwater ordinance Ch. 14 credits rain harvesting toward post-construction stormwater requirements.
Unpermitted large cistern connection to plumbing: UDC violation $100 to $1,000. Potable use without treatment: health code violation. Improper mosquito screening: public nuisance $50 to $200.
