Section 4464-12.0 - Water Slide Flume

12.1 General Requirements

12.1.1 Except as otherwise noted previously and in this Section, water slide flumes shall comply with all other requirements of these Regulations.

12.2 Splash Pool Design and Depth

12.2.1 In order to facilitate prompt, safe exiting by bathers, all splash pools shall have either a set of steps along the entire length of the exit side (side opposite the flume terminus), or a floor that slopes upward to meet the water surface.

12.2.2 The steps or upward sloping floor shall have one (1) handrail per flume or one (1) handrail every seven (7) feet, whichever is greater.

12.2.3 Ladders shall be prohibited.

12.2.4 The depth of the splash pool at the flume end shall be at least three (3) feet and not more than four (4) feet, and this depth shall be maintained for at least twenty (20) feet in front of the flume end.

12.2.5 The floor slope shall not exceed one (1) foot in seven (7) feet and all slopes shall be constant.

12.3 Flume End

12.3.1 Flumes shall terminate either at a depth of at least six (6) inches below the splash pool operating water level, or not more than two (2) inches above the splash pool operating water level, provided the flume is level for at least the last ten (10) feet.

12.3.2 The distance between the side of any flume end and the side of the splash pool shall be at least five (5) feet.

12.3.3 The distance between the sides of adjacent flumes shall be at least six (6) feet and adjacent flumes utilizing the same splash pool shall be parallel at the ends.

12.4 Decks and Walkways

12.4.1 A deck at least ten (10) feet in width shall be provided along the entire exit side of the splash pool.

12.4.2 All walks and steps from the exit side to the top of the flume shall be: at least four (4) feet wide;

12.4.3 constructed of concrete or other slip resistant material approved by the Division;

12.4.4 smooth, easily cleanable and properly maintained;

12.4.5 and separated from any flume by a physical barrier such that people on the walks or steps cannot reach the flumes.

12.5 Recirculation System

12.5.1 The water slide flume recirculation system shall be capable of providing a minimum of twenty-four (24) turnovers of the splash pool and pump reservoir volume per day [one (1) every hour] against the maximum head.

12.6 Pump Reservoirs

12.6.1 Pump reservoirs shall be separate from the splash pool, shall be made of concrete or other impervious material with a smooth slip-resistant finish, and shall be connected to the splash pool by a weir.

12.6.2 The minimum pump reservoir volume shall be equal to five (5) minutes of the combined flow rate in gpm of all water slide flume pumps. Pump reservoirs shall be accessible only to authorized individuals.

12.6.3 Access decks shall be provided.

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

12.6.5 The pump reservoir shall have a minimum of one (1) main drain with separate piping and valve to the filtration system.

12.6.6 Pumps shall have check valves on all discharge lines.

12.7 Perimeter Overflow Gutters and Surface Skimmers

12.7.1 All splash pools and pump reservoirs shall have either perimeter overflow gutters or surface skimmers which effectively remove any floating material and are connected to the recirculation system.

12.7.2 Where perimeter overflow gutters are used, they are not required along the weirs or under the flume end.

12.7.3 Where surface skimmers are used, one (1) shall be in the splash pool and one (1) shall be in the pump reservoir.

12.7.4 Where an odd number of surface skimmers are required they shall be positioned appropriately based on the size of the splash pool and pump reservoir.

12.8 Disinfection

12.8.1 Water slide flume pools may be permitted to manually add a halogen disinfectant, in addition to the automatic feeder, if it can be done somewhere other than the flume or splash pool.

12.9 Special Purpose Pools

12.9.1 General Requirements

12.9.1.1 The Division shall require compliance with any Sections of these Regulations which are deemed necessary, to assure the health and safety of special purpose pool bathers.
