Water restrictions in Williamson County, TN — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Tennessee has no statewide watering mandate, and water-abundant Williamson County sits in the Harpeth River basin. Any lawn-watering limits come from your local utility district, such as Milcrofton, Mallory Valley, or a city system, during drought.
Williamson County does not set countywide lawn-watering rules. Tennessee imposes no statewide water-conservation mandate, and the region is generally rainfall-rich, drained by the Harpeth River and its tributaries. Water service is split among several providers: Milcrofton Utility District, H.B. & T.S. Utility District, Mallory Valley Utility District, the Nolensville-College Grove utility, and city systems in Franklin, Brentwood, and Spring Hill. Any outdoor-watering restrictions, such as odd/even day schedules, are declared by your specific provider during drought, so check the utility that bills you. Rain barrels and efficient irrigation are encouraged.
Set by your water provider. Drought-stage watering violations typically bring a warning, then escalating fines and, for repeat offenders, possible service action.
