Okla. Admin. Code § 310:315-7-12

Current through Vol. 42, No. 4, November 1, 2024

Section 310:315-7-12 - Water recreation attractions

(a)General. Water recreation attraction projects require special consultation with the Department in order that consideration can be given to concepts of design variations and to areas where potential problems may exist. In addition to the requirements of this section, compliance is required with all other applicable sections of this chapter. Plans for supervision, attendants, and lifeguards will be an important feature to be considered for water recreation attractions, and shall be presented in the engineering report accompanying plans and specifications.

(b)Water slides.

(1)Recreational water slide. A recreational water slide facility shall consist of one (1) or more flumes, plunge pool, a pump reservoir, filtration, disinfection, and chemical treatment facilities.

(2)Water slide plunge pool. Plunge pools are located at the base of slide flumes. They shall be constructed of concrete or other impervious materials with a smooth slip-resistant finish. The plunge pool design shall be built according to the slide manufacturer's requirements/recommendations and the design engineer of the project or in compliance with the following standards:

(A) The minimum plunge pool operating water depth at the slide flume terminus is three (3) feet. This depth shall be maintained for a minimum distance of ten (10) feet in front of the slide terminus from which point the plunge pool floor may have constant upward slope to allow a minimum water depth of two (2) feet at the base of the steps. The floor slope cannot exceed one (1) foot in ten (10) feet. The plunge pool water depth shall be commensurate with safety and the ease of exit from the plunge pool.

(B) The plunge pool dimension between any slide flume exit or terminus and the opposite side of the plunge pool is a minimum of twenty (20) feet excluding steps.

(C) The slide flume terminus shall be at a minimum depth of six (6) inches below the plunge pool operating water surface level or it may be at the water surface level or up to a maximum of two (2) inches above the water surface level provided the terminal portion of the slide flume is parallel to the water surface for a minimum distance of ten (10) feet. The minimum distance between any plunge pool side wall and the outer edge of any slide flume terminus is four (4) feet. A minimum length of ten (10) feet of slide flume shall be perpendicular to the plunge pool wall at the exit end of the flume(s).

(D). The main drain piping shall be sized to handle one hundred (100) percent of the design flow rate of the filtration system in accordance with 310:315-7-14.

(E) The plunge pool floor shall slope to the main drain(s) and the slopecannot exceed one (1) foot in ten (10) feet.

(F) Plunge pool decks shall meet the following requirements:

(i) have a minimum 10 foot width along the exit side;

(ii) have a minimum six (6) inch high curb; and

(iii) slope (drain) away from the plunge pool unless the curb is located at the outside perimeter of the deck. If the curb is located at the outside perimeter of the deck, the plunge pool deck shall slope to the plunge pool and/or pump reservoir or to deck drains which discharge to the same. All slopes shall be a minimum of three (3) inches in ten (10) feet.

(3)Pump reservoirs. Pump reservoirs shall be made of concrete or other impervious material with a smooth slip-resistant finish and shall be connected to the plunge pool by a weir. Pump reservoirs shall be for the slide pump intakes.

(A) The minimum reservoir volume shall be equal to two (2) minutes of the combined flow rate in gpm of all filter and slide pumps.

(B) Pump reservoirs shall be isolated by a locking cover or enclosure and accessible only to authorized individuals.

(C) Access decks shall be provided for the reservoir such that all areas are accessible for vacuuming, skimming, and maintenance. The decks shall have a minimum width of three (3) feet and a minimum slope of three (3) inches in ten (10) feet away from the reservoir. A minimum six (6) inch high curb shall protect the reservoir.

(D) Pump reservoir slide pump intake(s) shall be located in the pump reservoir and designed to allow cleaning without danger of operator entrapment.

(E) The pump reservoir shall have a main drain, complying with OAC 310:315-7-14.

(4)Slide pump check valves. Slide pumps shall have check valves on all discharge lines.

(5)Perimeter overflow gutters or skimmers. Plunge pools and pump reservoirs shall have perimeter overflow gutter systems and/or skimmers which shall be an integral part of the filtration system.

(A) Perimeter overflow gutter systems shall meet the requirements of OAC 310:315-7-14 except the gutters are not required directly under slide flumes or along the weirs which separate plunge pools and pump reservoirs.

(B) Surface skimmers may be used in lieu of perimeter overflow gutters and shall be appropriately spaced and located according to the structural design. Unless an overflow gutter system is used, a minimum of two (2) surface skimmers each shall be provided in the plunge pool. Skimmers are subject to OAC 310:315-7-14.

(6)Water slide recirculation-filtration equipment.

(A) The recirculation-filtration system of water slides shall recirculate and filter a water volume equal to the total water volume of the facility in a period of one (1) hour or less.

(B) Minimum filter area requirements shall be twice the filter areas specified for the recirculation rate stipulated in OAC 310:315-7-15.

(C) Any filtration system pump which takes suction directly from the plunge pool and reservoir shall have a minimum eight (8) inch diameter hair and lint strainer, meeting the requirements of OAC 310:315-7-14 on the suction side of the pump.

(7)Water slide chemical feed equipment. Feeders for pH adjustment complying with OAC 310:315-7-16 and capable of meeting the feed rate for the specific installation shall be provided.

(c)Water amusements, wave pools, and tube rides. The recirculation-filtration system of water amusements, wave pools, and tube rides shall be capable of a minimum of one (1) turnover every six (6) hours.
