Current through Vol. 41, No. 20, July 1, 2024
(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.
