      (4)   The size, number and locations of the spray pad drains shall be determined and specified so as to assure water does not accumulate on the spray pads. Flow through the drains to the spray pad treatment tank shall be under gravity, and direct suction outlets from the spray pad are prohibited.
      (5)   Valves and piping shall be provided in the spray pad drain system to allow for discharging spray pad water to waste prior to returning to the spray pad treatment tank.
      (6)   A continuous clear deck shall surround the entire spray pad perimeter. It shall be not less than five feet wide. The deck shall be of a uniform, easily cleaned, impervious material and be protected from surface runoff.
      (7)   The deck shall be sloped at least one-fourth inch per foot to deck drains or grade.
      (8)   Deck drains, when used, shall be spaced and arranged so that not more than 400 square feet of area is tributary to each drain, and drains shall not be spaced more than 25 feet apart. There shall be no direct connection between the spray pad deck drains and the sanitary sewer system, the treatment tank, or the recirculation system.
      (9)   Carpeting shall not be permitted on the spray pad or decks.
      (10)   Hose bibbs shall be provided to facilitate flushing of the spray pad and deck areas and shall be provided with anti-siphonage devices.
      (11)   Spray features shall be designed and installed so as not to pose a tripping hazard, a hazard to patrons due to water velocity from the spray feature discharge, or other safety hazards.
      (12)   Artificial lighting shall be provided at all spray pads which are used at night, or which do not have adequate natural lighting, so that all portions of the spray pad and deck may be readily seen.
      (13)   All spray pad equipment and chemical storage rooms shall be provided with artificial lighting sufficient to illuminate all equipment and supplies.
      (14)   No electrical wiring shall pass overhead within a 20-foot horizontal distance of the spray pad.
      (15)   Ground-fault circuit interrupters shall be provided on all spray pads, for all lighting and other electrical circuits in the area of the spray pad. These devices may be required in an existing spray pad, when the permit-issuing official determines it is necessary to protect the safety of patrons.
      (16)   When water is supplied to the spray features by a pump which removes water directly from the spray pad treatment tank independent from the spray pad treatment tank filter pump, the turnover rate for filtration will be determined by the feature flow rate. The filtration flow rate for the spray pad treatment tank must be at least one-third of the design spray feature flow rate.
      (17)   When all of the water supplied to the spray features is filtered upon removal from the spray pad treatment tank before being supplied to the spray features, a reduced pumping rate for filtration/treatment of the spray pad treatment tank water can be used when the spray features are not in operation. However, a minimum four-hour turnover rate is required.
      (18)   The minimum flow rate through the filtration system for combined pool/spray pad systems shall be equal to or greater than the sum of the flow rate for the specific type pool as required in 410 I.A.C. 6-2.1 plus one-third of the spray feature flow rate.
      (19)   The spray pad treatment tank that receives the effluent water from the spray pad shall conform to the following specifications:
         (a)   The volume of the water in the spray pad treatment tank shall be sufficient to assure continuous operation of the filtration system. The capacity shall be measured from six inches above the uppermost pump inlet to the bottom of the overflow waste outlet.
         (b)   The spray pad treatment tank must be designed to provide ready access for cleaning and inspections, and be capable of complete draining. An overflow pipe to convey excess water to waste must be provided.
         (c)   The spray pad treatment tank shall be constructed of materials which are inert, corrosion resistant, nontoxic, and watertight such as concrete, fiberglass, stainless steel, etc., which can withstand all anticipated loadings under full and empty conditions.
         (d)   An automatic water level controller shall be provided for the spray pad treatment tank.
         (e)   The makeup water shall be introduced into the spray pad treatment tank through an air gap or by another method which will prevent back flow and backsiphonage.
         (f)   A screen or similar device shall be provided through which all water from the spray pad shall pass before entering the spray pad treatment tank or another method/process described to provide for removal of debris on the surface layer of the spray pad treatment tank water.
         (g)   An adequate number of filtered/treated water inlets shall be provided and located for complete mixing and circulation of treated water within the spray pad treatment tank.
         (h)   There must be at least one main spray pad treatment tank drain suction outlet supplying water to the spray pad treatment tank filtration system. It shall be provided at the deepest point in the spray pad treatment tank.
         (i)   Drain outlets shall be protected by grating. Openings in the grates shall not be over one-half inch wide. Gratings or drain covers shall not be removable without the use of tools.
         (j)   The recirculation piping and fittings shall be of nontoxic material, resistant to corrosion, and able to withstand operating pressures suitable for water supply use.
         (k)   The pipes, fittings and valves of the recirculation system shall be sized so that velocities do not exceed six feet per second under suction, ten feet per second under pressure and three feet per second in gravity flow. The velocities may be exceeded when hydraulic computations indicate higher velocities will not adversely affect the spray pad treatment system.
         (l)   All equipment and piping shall be designed and fabricated to drain completely by use of drain plugs, drain valves or other means. All piping shall be supported continuously or at sufficiently close intervals to prevent sagging. All suction piping shall be sloped in one direction, preferably toward the pump. All supply and return pipelines to the spray pad shall be provided with insertable plugs or valves to allow the piping to be drained to a point below the frost line. Provision shall be made for expansion and contraction of pipes.
         (m)   A hair and lint strainer shall be provided through which all water shall pass before entering the pump. The strainer shall be of rigid construction, fabricated of corrosion-resistant material and sufficiently strong to prevent collapsing when clogged. The openings shall be no greater than one-eighth inch in any dimension. The total clear area of all openings shall be at least four times the area of the connecting pipe. The strainer shall have a quick-opening cover. Spare strainer baskets shall be provided. In systems where the filter is located on the suction side of the pump, strainers are not required.
         (n)   The recirculation pump shall have adequate capacity to meet the design requirements of the spray pad treatment tank, including filter backwashing. It shall be of a self-priming type if installed above the hydraulic gradient. A gauge that indicates both pressure and vacuum shall be installed on the pump suction header and a pressure gauge shall be installed on the discharge side of the pump.
         (o)   A means of continuously measuring rate of flow shall be provided in the recirculation system. For sand filters, the flow-measuring equipment shall be located where the backwash flow rate can also be determined. The indicator shall be capable of measuring at least one and one-half times the design flow rate and shall be accurate within 10% of true flow. The indicator shall have a range of readings appropriate for the anticipated flow rates, and be installed where it is readily accessible for reading and maintenance and with straight pipe upstream and downstream of any fitting or restriction in accordance with the manufacturer’s recommendation.
         (p)   Automatic devices are required for regulating the rate of flow through the filtration system and flow to the spray features.
         (q)   A spray pad treatment tank treatment system shall have one or more filters. It shall be installed with adequate clearance and facilities for ready and safe inspection, maintenance, disassembly and repair.
   (F)   If a spray ground is connected to a potable water supply and is discharged directly to a sanitary sewer system, fencing requirements do not apply.
   (G)   Newly constructed pools are not permitted to have vinyl liners.
