Current through Register Vol. 48, No. 9, September 27, 2024
1.
Applicability. Requirements of this section are applicable to all new
construction and alterations of existing public swimming pools.
2. Type "E" Pools. In addition to all other
applicable requirements of these regulations found in Section C, Type "E" pools
must also have a recirculation system for filtering and disinfecting the water
used, except as may be justified to and found acceptable by the
Department.
3. Waterslides and
Flumes.
(a) The slopes and radii of each
flume and flume section must be acceptable to the Department. Each flume must
be properly banked when used in any curved section; regardless of degree of
curvature. Each flume must be designed to enter the landing pool in a safe
manner. The landing pool must be of dimensions suitable to prevent accidental
collision between users and/or walls. It may be necessary to obtain a certified
inspection permit from the South Carolina Department of Labor if the law so
provides for same.
(b) All sections
of a flume must be properly formed and sealed together so as to prevent
possible abrasions or injuries, i.e., no protrusions or gaps between sections.
All protruding edges need to be deburred and polished so that there will be no
cutting, pinching, puncture, or abrasion hazards. The permit for this type of
facility will be invalidated, unless a good safety record is
maintained.
(c) Details on
submission of plans for waterslides must include:
(i) Detailed layout of the flumes indicating
elevations, slopes, lengths of sections, and radius of each curve in the
flumes.
(ii) Detailed cross
sectional views of the flume on a straight away and going into all curves. The
average water depth must be indicated.
(iii) Structural details of starting pools,
flumes, landing pools, and if applicable, surge pools.
(iv) Total water volume for the whole
waterslide facility.
(v) Top and
profile views of the starting pool.
(vi) Top and profile views of the surge pool
if applicable.
(vii) Top and
profile views of the landing pool to include all equipment and applicable
equipment spacing with all dimensions given or drawn to scale.
(d) Flume Design Criteria:
(i) The overall average slope of a flume
shall conform to the design criteria of the recommendations of the ASTM F 2376,
"Standard Practice for Classification, Design, Manufacture, Construction, and
Operation of Water Slide Systems."
(ii) The slope of each flume section shall
conform to the design criteria of the recommendations of the ASTM F 2376,
"Standard Practice for Classification, Design, Manufacture, Construction, and
Operation of Water Slide Systems."
(iii) Each flume shall be properly banked
when used in any curved section; regardless of the degree of curvature. This is
to properly ensure that the slider's body will remain within the
flume.
(iv) Test runs down each
channel shall be conducted to ensure its safety prior to formally opening the
facility.
(v) A detailed
engineering analysis of the flume structure must be submitted by the engineer
assuming responsibility for the facility to ensure the strength and integrity
of the material and structure under all circumstances.
(vi) Distance between the side of a flume
exit and a landing pool wall shall be a minimum of five (5) feet.
(vii) Distances between sides of adjacent
flume terminuses shall be a minimum of six (6) feet.
(viii) The distance between a flume exit and
the opposite side of the landing pool or other obstruction(s) shall be a
minimum of twenty (20) feet.
(ix)
Flumes shall terminate a maximum of two (2) inches above the water surface and
the flume must be level for a minimum distance of ten (10) feet from the
flume's end. Flumes cannot terminate at an angle.
(x) Safe entry into the landing pool shall be
provided through a deceleration distance of at least twenty (20)
feet.
(e) In addition to
requirements for public swimming pools the following must also be met:
(i) A one hour filter turnover time is
required.
(ii) Where night use is
allowed, area lighting of at least two (2) watts per square foot of deck area
shall be provided at the landing pool, along the slide, and at the starting
pool.
(iii) Adequate supervision of
all slide flumes entry and exit points must be provided.
(f) All items not covered above with regard
to Type "E" Pools shall use the current edition of the ASTM F 2376, "Standard
Practice for Classification, Design, Manufacture, Construction, and Operation
of Water Slide Systems" as guidelines.
4. Lazy Rivers. Lazy rivers with volumes of
60,000 gallons or greater shall have a minimum turnover time of six (6) hours.
Those with volumes less than 60,000 gallons shall have a minimum turnover time
of four (4) hours.
5. Wave Pool,
Activity Pools and Kiddie Play Parks. Wave and activity pools with volumes of
60,000 gallons or greater shall have a minimum turnover time of six (6) hours.
Those with volumes less than 60,000 gallons shall have a minimum turnover time
of four (4) hours. Kiddie Play Parks shall have a minimum turnover time of one
(1) hour.
6. Recirculation System.
A recirculation system consisting of pumps, motors, piping, filters, inlets,
outlets, disinfecting and other water conditioning equipment and necessary
accessories must be provided for water purification in accordance with water
quality criteria contained herein and must be designed to completely turnover
at the rate required in Paragraphs 4 and 5 above. The recirculation system
shall be designed to operate on a twenty-four (24) hour basis. The normal
pattern of recirculation developed must be fifty (50) percent flow through the
overflow or skimming facilities and fifty (50) percent through the main drains.
The recirculation system must be designed with adequate capacity such that one
hundred (100) percent of the recirculation flow can pass through the overflow
or skimming facilities and 100 percent through the main drain. Waterparks may
have several pools on one (1) main recirculation system provided it is proven
to the Department that each pool meets the required turnover rate and the
Department finds the overall design acceptable.
7. Automatic Controllers. All new Type "E"
pools with water volumes of 1,500 gallons or less, shall be equipped with
automatic controls to provide adequate feed rate of halogen and pH adjustment
chemicals in order to keep the disinfectant and pH at the required levels on a
continuous demand basis. A warning light or indicator shall be provided in a
visible location for supervisory control. The device shall indicate absence of
chemicals in feeders, improper adjustment of chemical dosage, or any other
mechanical or operational malfunctions, e.g. recirculation flow
stops.
8. Pool Deck. The pool deck
must be constructed in accordance with R.61-51.C.6.
