Current through Vol. 42, No. 1, September 16, 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.
(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.
