Water restrictions in Davidson County, TN — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Davidson County has no permanent mandatory outdoor water restrictions. Metro Water Services issues voluntary staggered watering advisories during drought. Nashville averages ~47 inches of rainfall annually and is not subject to arid-region restrictions.
Metro Water Services (MWS) provides water service throughout Davidson County and manages conservation during high-demand periods. In August 2024, MWS issued a voluntary staggered irrigation advisory: odd-numbered addresses water on Monday/Wednesday/Friday; even-numbered on Tuesday/Thursday/Saturday. This advisory was voluntary and not a mandatory ordinance. Nashville's temperate climate and ~47 inches of annual rainfall mean permanent watering restrictions are not typical. MWS may issue emergency mandatory restrictions if reservoir levels fall critically low; residents should monitor MWS communications during drought events.
No fines for voluntary advisory non-compliance. Emergency mandatory restrictions (if declared) would carry enforcement authority.
