City swimming pools must comply with the Hotel, Food Service Establishment, and Public Swimming Pool Inspection Act of 1985. The commissioner of health may grant variances and waivers that do not result in a health or safety hazard. T.C.A. § 68-14-303(3).
Any public swimming pool owned by a "public entity" that is more than 30,000 square feet must have a full-time, staffed lifeguard station for each 6,000 square feet, or major portion thereof, available for public use. The commissioner of environment and conservation may increase the size of the area requiring a single lifeguard station. T.C.A. § 68-14-402.
