89.150. - Design and construction requirements.
The design and construction of all private residential swimming pools shall comply with the following:
(1) Structural design. The pool structure shall be engineered and designed to withstand the expected forces to which it will be subjected.
(2) Overflow and surface drainage. The pool and surrounding area shall be constructed and arranged in such a manner that no splash or overflow water shall return to the pool. No surface or roof drainage shall be permitted to enter the pool.
(3) Finish. Pool floor and walls shall have a cleanable, white or similar light-colored and impermeable surface.
(4) Handholds. Handholds shall be provided and shall not be more than nine (9) inches above the normal water line and shall extend around the entire periphery of the pool.
(5) Pool deck. Unobstructed deck areas not less than forty-eight (48) inches wide shall be provided to extend entirely around the pool. The deck surface shall be such as to be smooth and easily cleaned and of nonslip construction. The deck shall have a pitch of at least one-fourth (¼) inch to the foot, designed so as to prevent back drainage into the pool. If deck drains are provided, drain pipe lines shall be at least two (2) inches in diameter and drain openings shall have an open area of at least four (4) times the cross-sectional area of the drain pipe. The deck drain system shall have indirect connection to the sanitary sewer. The deck drains shall not be connected to the recirculation system piping. No deck, other than the ground surface, shall be required for any pool that is totally above ground and which is less than four (4) feet in height.
(6) Steps or ladders. One (1) or more means of egress in the form of steps or ladders shall be provided from any pool having a water depth of thirty-six (36) inches or more. Treads of steps and ladders shall be equipped with nonslip material.
(7) Plumbing. All plumbing connected to such swimming pool shall be installed in accordance with the Minnesota State Plumbing Code, Minn. Rule 4714.
(8) Water supply. The water supply serving the swimming pool shall be potable water or of a quality otherwise acceptable to the commissioner of health. All portions of the water distribution system serving the swimming pool and auxiliary facilities shall be protected against backflow. Water introduced into the pool, either directly or to the recirculation system, shall be supplied through an air gap. When such connections are not possible, the supply shall be protected by a suitable backflow preventer installed on the discharge side of the last control to the fixture, device or appurtenance.
(9) Drainage. Pools shall be equipped with facilities for completely emptying the pool to the sanitary sewer, or other suitable disposal unit acceptable to the building official.
There shall be no direct physical connection between the sewer system and any drain from the swimming pool or recirculation system. Any swimming pool or gutter drain or overflow from the recirculation system when discharged to the sewer system, storm drain, or other approved natural drainage course shall connect through a suitable air gap or air break so as to preclude the possibility of backup of sewage or waste into the swimming pool piping system.
The water from the pool shall not be drained onto the streets or sidewalk or any other public property or private property not owned by the pool owner.
(10) Heaters. All gas-fired or oil burning swimming pool heaters and boilers shall comply with the plumbing code and heating code of the city. (Ord. No. 2019-034, § 1, 8-23-19)
