Additional hose bibbs shall be provided as necessary, and at intervals so as to permit adequate cleaning of the deck and toilet facilities using a maximum of 100 feet of hose when laid across the deck surface.
Organic material and inorganic pervious material shall be separated from the otherwise required deck by an additional 5 feet of deck.
Organic material and inorganic pervious material shall be installed in a 4-inch depression surrounded by a 42-inch high barrier.
Sand play areas may not be located within a pool enclosure unless all of the following are met:
The sand play area is separated from the deck by a 42-inch high rope and bollard or other fence barrier.
Foot or body showers shall be provided at any entrances to the deck from the sand play area.

A water circulation system consisting of pumps, piping return inlets and suction outlets, filters and other necessary equipment shall be provided that complies with all of the following requirements:
(1) Turnover rate.
Circulation system equipment shall be designed to produce a turnover rate as specified in Table 390.14-1 or Table 390.14-2.
SPS 390.14 Note
Note: See the appendix for further information.
a Calculate an average turnover time for multi-sectional basins.
b For pool types not listed herein, contact the department.
c Based on flow and pressure drop with a clean filter condition.
d Or as otherwise approved by the department.
N/A Not applicable
a The number of persons is equal to the posted patron load.
SPS 390.14 Note
Note: A therapy area within a multi-section pool having a temperature of
< 93 oF is considered to be an activity pool.
(2) Separate systems.
The circulation system shall be separate for each public swimming pool or water attraction.
Except as provided in pars. (b)
, public swimming pool or water attraction circulation systems may not serve slide or spray features.
A maximum of 10 percent of the required circulation system rate may be provided for the lubrication of slides or to spray features.
Flow in excess of the required circulation rate may serve slides and spray features.
Circulation system equipment, including but not limited to pumps, skimmers, filters, gauges, meters and thermometers, shall be readily accessible for inspection, repair or replacement.
(5) Component standards.
Equipment that is within the scope of ANSI/NSF 50, circulation system components and related materials, shall be listed by an acceptable listing agency to meet ANSI/NSF 50 or equivalent.
Pool equipment and related piping shall be supported to prevent damage from misalignment and settling.
Pool equipment shall be installed in accordance with manufacturer's printed instructions and as specified in this chapter. If there is a conflict between the manufacturer's printed instructions and requirements of this chapter, the requirements of this chapter shall take precedence.
Pool piping shall be sized to permit the rated flows for filtering and cleaning without exceeding the maximum design head of the pump.
A pump suction compound gauge shall be included in all circulation systems.
A pump discharge gauge shall be located upstream of all throttling valves.
A filter pressure gauge shall be included serving all filters in circulation systems.
A flow meter capable of displaying flow during filtration shall be included in all circulation systems.
Circulation system piping that is installed onsite shall be subjected to an induced static hydraulic pressure test at 25 pounds per square inch for at least one hour.
Filters shall be specified so that when operated and maintained in accordance with the manufacturer's printed instructions, the system provides the water clarity required in ch. DHS 172
Filters other than high rate sand filters shall be specified so that the maximum flow rate does not exceed those under ANSI/NSF 50.
High rate sand filters shall be specified so that the maximum flow rate does not exceed 15 gallons per minute per square foot or bed surface area.
Pressure-type filters shall be provided with a means to permit the release of internal pressure.
Filters incorporating an automatic air vent as the principal means of air release shall have a lid that provides a slow and safe release of pressure as a part of the design and have manual air release in addition to the automatic release.
Separation tanks used in conjunction with a filter tank shall comply with subd. 2.
The following statement shall be placed within the area of the air release so as to be clearly visible: "WARNING. DO NOT START UP THE SYSTEM AFTER MAINTENANCE WITHOUT FIRST OPENING THE AIR RELEASE AND PROPERLY ASSEMBLING THE FILTER AND SEPARATION TANK."
Circulation piping shall be listed as meeting one of the following methods:
All circulation piping shall be listed to withhold a pressure 50 percent greater than the maximum design pressure.
All circulation pumps shall be capable of providing the design flow rates at one of the following minimum total dynamic heads:
A maximum total dynamic head value recommended by the filter manufacturer that allows the filter to function under all operating conditions.
Pumps located below the waterline of a basin shall have isolation valves installed on suction and discharge lines.
Pumps located above the waterline of the pool shall be self-priming or the system shall be designed to provide a means for priming.
Intake strainers shall be provided upstream of all circulations pumps on pressure filter systems.
