Rainwater harvesting is legal in Sumner County. Tennessee places no restriction on residential collection, so rain barrels and cisterns for garden and lawn use are fine. Only large plumbed systems or drinking-water use trigger permits or treatment.
Collecting rainwater for irrigation and other non-potable uses is allowed throughout Sumner County. Tennessee has no statute limiting residential rainwater capture, and cutting runoff into Old Hickory Lake and the Cumberland River supports local stormwater goals. Standard rain barrels need no permit. Large cisterns tied into plumbing, or any system used for drinking water, must meet building and health-department standards. If you belong to an HOA in a lake subdivision, check its rules on visible barrel placement before installing.
None for ordinary residential collection. A large cistern installed without a required building or plumbing permit is a standard code violation subject to correction and fees.
