State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
(1) RECIRCULATION. All public wading pools that have submerged outlets must have at least two outlets for each pump. Each public wading pool , except those in subsection (1)(c) of this rule, must have a recirculation rate that meets or exceeds subsection (1)(a) or (1)(b) of this rule, whichever is greater:
(a) A 60-minute turnover time; or
(b) When skimmers are used, each skimmer must be designed to skim between 30 to 45 gpm water flow, when 70 percent of the recirculation flow is through the skimmers ((# of skimmers) x (30 to 45 gpm design flow)/0.70 = gpm recirculation rate). The skimmer piping must be designed to handle 100 percent of the recirculation rate.
(c) Spray pools, water playgrounds and interactive fountains that do not pond water and that use potable water once and dispose of it without recirculating it are not regulated or licensed by the Division .
(2) SEPARATE SYSTEM. Each public wading pool must have its own separate recirculation system.
(3) SURFACE SKIMMING. The pool must be designed to skim the water surface continuously. The Division may consider overflow structures such as intermittent fixed weir overflow and trench drains, if shown to be comparably compliant to gutter systems. The Division or its agent may consider alternate overflow designs if the designer shows that adequate skimming and water mixing occur when non-traditional designs are proposed.
(a) SKIMMERS must be listed as meeting ANSI/NSF Standard 50 requirements by a nationally recognized testing organization approved by the Division . A skimmer must be provided for every 400 square feet (37 m2) of water surface area or fraction thereof and provide flow in the amount determined in subsection (1)(b) of this rule.
(b) GUTTERS AND TRENCH DRAINS. Gutters allow skimming along the entire edge of the gutter. Generally the gutter extends completely around the perimeter of the pool. A TRENCH DRAIN is used much like a gutter, and is installed in zero-depth areas where an overflow lip cannot be provided. Trench drains are installed at the same angle as the floor. To skim properly, the bottom edge of the trench drains must be level to a very small tolerance and slightly below the water surface.
(A) To determine the minimum amount of surge capacity needed for the pool, add subparagraphs (3)(b)(A)(i) and (ii) of this rule and provide this capacity by installing a surge tank, or any combination of surge tank, gutter, or trench drain:
(i) Provide a minimum surge capacity equal to an amount determined by calculating eight minutes of recirculation flow (8 x recirculation rate = surge capacity); then
(ii) Add the surge needs of any spray feature or water activity system. Allow an amount equal to at least two minutes of feature recirculation flow, or as recommended by the manufacturer , whichever is greater.
(B) Install an automatic fill device, to maintain the water level, on all wading pools with gutters or trench drains.
(4) INLETS. Locate the inlets to evenly distribute treated water to all parts of the wading pool and to move debris to the overflow and drain systems. The designer is responsible for demonstrating that the inlet system will provide adequate circulation to all portions of the wading pool :
(a) Use floor inlets on all wading pools more than 30 feet wide (9.1m), and on zero-depth pools.
(b) In-floor cleaning systems, or other products that may cause a tripping or stubbing hazard, are not allowed.
(c) All inlet fittings must have tamper-proof screws or attachments that cannot be removed except with tools. Inlet fittings will be in place whenever the pool is in use.
(5) SUBMERGED SUCTION FITTINGS AND MAIN DRAINS. All submerged suction fittings must be installed according to the standards below.
(a) Wading pool main drains must be installed in the deepest part of the pool and be designed to minimize tripping and toe stubbing hazards.
(b) Main drain and submerged suction outlets must be designed with sufficient open area that the maximum velocity through the cover does not exceed the cover's listed flowrate.
(c) All hardware and fittings must be supplied by the manufacturer and installed according to the manufacturer 's directions.
(d) Main drain and submerged suction fitting systems must provide entrapment, hair entanglement and evisceration protection.
(A) Main drains and submerged suction fittings and sumps must be compliant with the requirements of ANSI/APSP 16 - Suction Fittings for Use in Swimming Pools, Wading Pools, Spas, and Hot Tubs (2011). The cover must be labeled and include; "VGB 2008," the logo of the third party listing agency, the standard for which it was tested, the gallons for which it was approved and the location it is to be placed.
(B) Maintain any documentation about your main drain or suction fitting.
(C) All submerged suction fittings must be installed with a sump designed and approved by the manufacturer for that outlet cover.
(D) All field built sumps must be designed by an Oregon registered engineer and must be built so the opening of the suction pipe is no closer than 1.5 times the pipe's inside diameter from the bottom of the listed suction cover/plate.
(E) Two or more outlets must be provided. They must be separated by at least three feet (measured from the midpoint of the main drain connector pipe centerlines) between the furthest fittings, or be on separate planes, placed such that they cannot be blocked by one person .
(i) The outlets must be sized to handle an equal portion of at least 200 percent of the recirculation flow.
(ii) The outlets must be installed so that they cannot be isolated from one another; no intervening valves.
(iii) The main drain or submerged suction fitting-piping going back to the pump must be located in the hydraulic middle of the fitting connector piping, and must be the same size as the connector piping.
(6) BROKEN OR MISSING GRATE FITTINGS. If the pool operator finds that a suction fitting is broken or missing, they must close the wading pool immediately, shut down the recirculation system and remain closed until the fitting has been replaced.
(7) BASIN DESIGN. The slope of the pool bottom can be no more than 1 in 12. Eight inches (200 mm) is the maximum water depth allowed at any edge of the pool accessible from the deck. When perimeter water depths exceed eight inches (200mm) at the edge of the pool, stairs and handrails complying with the requirements of OAR 333-060-0080(1), (3), (4)(b), (7), (8) and (9), must be provided at the designated entry points.
(8) DECKING. Unobstructed decking, five feet (1.5 m) or more in width must be provided around the wading pool perimeter. When a wading pool is adjacent to a swimming pool , it must be located near the shallow end of the swimming pool , with a minimum of nine feet (2.7 m) of deck between the pools.
(9) ENCLOSURE. Enclose the wading pool area, as required by OAR 333-060-0105. Spray pools, water playgrounds, and fountains that do not pond water may comply with paragraph (11)(c)(E) of this rule in lieu of providing an enclosure.
(10) DEPTH MARKING:
(a) The operator must indicate the maximum pool depth in feet and inches, with a sign near each entrance to the wading pool .
(b) Depth markings must be placed around the pool perimeter indicating the water depth at the edge, following the requirements in OAR 333-060-0065.
(c) Pools with a zero-depth edge are not required to have perimeter depth markings, but are still required to provide the maximum depth signs.
(d) Pools and fountains that do not pond water are not required to have depth markings or maximum depth signs.
(11) SPRAY FEATURES AND PLAY EQUIPMENT. Fountains, sprays, slides and similar features may be installed, if specifically designed for aquatic installation:
(a) WATER SOURCE . Water-using features must be designed and installed to draw their water supply from the main drain or similar fitting, surge tank, trench drains or gutters, but not from the skimmers. The main drain fittings and the related piping must be sized for 100 percent of the pool recirculation rate plus 100 percent of the capacity of any feature pump routed through the fittings. The sizing of the feature pump must be based on 20 ft. TDH (59,000 Pa), unless the actual TDH is calculated.
(b) EQUIPMENT DESIGN AND INSTALLATION. Play equipment shall be designed and installed to meet all applicable standards of the CPSC Handbook for Playground Safety (2010 edition), and ASTM F2461, Standard Practice for Manufacture, Construction, Operation, and Maintenance of Aquatic Play Equipment - 2009:
(A) Applicable requirements include equipment design and construction, proper anchoring, entrapment protection, protrusion safety, and safety use-zone sizing. All equipment shall be designed for use in pools.
(B) Play equipment must be designed to be difficult to climb, unless the equipment is specifically designed for climbing and provided with safety zones and impact attenuating surfaces acceptable to the Division .
(C) Swings are not allowed.
(D) Obstructions extending from the walls or the bottom of the wading pool are not permitted, unless a designed part of the play equipment, with provisions made for safety and good water circulation.
(E) "Children's Activity Slides" are small, low exit velocity slides designed for use by small children in shallow water. They must be designated by the manufacturer for use in 24 inches (0.6 m) or less of water, and installed as recommended by the manufacturer . Other types of slides are not allowed.
(F) Spray pools, using potable water, must comply with all requirements concerning basin design, materials, entrapment protection, fall protection, and safety during construction of the pool, and must be maintained and operated in a safe and healthy manner.
(c) SPRAY POOLS or WATER PLAYGROUNDS. Spray pools or water playgrounds are basins containing spray features intended for recreational use, but that do not collect water in the basin. If the water is captured and recirculated, the pool shall meet the requirements of OAR, chapter 333, division 60. If potable water is used once and drained to waste, the spray pool or water playground is not regulated or licensed under these rules:
(A) Design spray pools with a zero-depth design, with no walls in the basin.
(B) Spray pools do not require devices for skimming.
(C) All water recirculated through the spray features shall be filtered and sanitized, or from a potable water source . Equipment capable of continuously supplying at least 0.25 ppm additional chlorine to the line returning water to the spray features must be provided, except when potable water is supplied, used once and drained to waste, or all the water is filtered and treated before being sent back to the water features.
(D) Slip-resistant, easy to clean and water impervious surfaces must be installed in the spray basin. Impact attenuating surfaces, basin surfacing materials with shock absorbing properties, for use with equipment addressed in subsection (11)(b) of this rule, will be considered, but must be water impervious, not conducive to bacteria and algae growth, and resistant to vandalism and damage. All impact cushioning materials must be approved by the Division for use in a wet environment.
(E) Spray pools do not require a security enclosure. At least six feet (1.9 m) of deck around the perimeter of the pool basin and sloped away from the basin must be provided.
