Water restrictions in Waukesha County, WI — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Waukesha County itself sets no countywide watering schedule. Outdoor watering restrictions (odd/even days, sprinkler hours) are imposed by each municipal water utility under Public Service Commission oversight. Southeastern Wisconsin is a state-designated groundwater management area.
Wisconsin groundwater is a public-trust resource, giving the DNR broad conservation authority, but day-to-day watering rules come from your local water utility, not the county. Utilities use staged programs: voluntary odd/even guidance escalating to mandatory odd/even watering, then limited days, then hand-watering only during shortages. Waukesha, Kenosha, Racine, Milwaukee and Ozaukee counties sit in a DNR-designated Southeastern Wisconsin groundwater management area reflecting depletion concerns. Check your city or village water utility for the current stage and any sprinkler-hour limits.
Utility watering-restriction fines are municipal; mandatory odd/even stages commonly carry fines (for example up to $100 per violation) set by the local utility, not the county.
