Operational Manual Section: RECREATIONAL WATER FACILITIES
  
6.1.1.1.1: Ensure that flow-through seawater supply systems for swimming pools are used only while the vessel is under way and at sea beyond 20 kilometers (12 miles) from nearest land.


  
6.10.1: Prohibit children in diapers or who are not toilet trained from using any RWF that is not specifically designed and approved for use by children in diapers.


  
6.2.1.1: For RWFs with skim gutters, ensure that the fill level of the RWF is to the level of the skim gutters. Design recirculation systems and equipment, including chemical control equipment, UV disinfection systems, filter, and pumps to maintain adequate water chemistry control while operating at the following minimum turnover rates: (1) swimming pool (VSP 2005 Construction Guidelines or earlier): 6 hours; (2) swimming pool (VSP 2011 Construction Guidelines or later): 4 hours; (3) children's pool: 0.5 hours; (4) wading pool: 1 hour; (5) whirlpool spa: 0.5 hours; (6) spa pool: 2 hours; (7) interactive RWF or activity pool less than 610 millimeters (24 inches) deep: 1 hour; (8) interactive RWF or activity pool greater than 610 millimeters (24 inches) deep: 2 hours; and (9) baby-only water facility: 0.5 hours. Ensure an RWF slide that is combined with a pool has a turnover rate that matches the rate for the pool.


  
6.2.2.2.3: Install chart recorders or electronic data loggers with security features that record pH and halogen measurements for each individual RWF. Ensure the sample line for the analyzer probe (monitoring) is either directly from the RWF or on the return line from each RWF and before the compensation tank. Install appropriate sample taps for analyzer calibration. In the event of equipment failure, measure free residual halogen and pH by a manual test kit at the RWF or return line at least hourly for whirlpool spas, spa pools, children?s pools, and wading pools and every 4 hours for all other RWFs. Record manual readings on a chart or log, retain for at least 12 months, and ensure that they are available for review during inspections. Complete repairs on malfunctioning halogen analyzer-chart recorders within 30 days of equipment failure. Provide an audible alarm in a continuously occupied watch station to indicate low and high free halogen and pH readings in each RWF.


  
6.3.1.1.4: Ensure that granular filters are backwashed at least daily until the sight glass indicates a clean flow and that the uniformity of the backwash action is observed, where possible. Ensure that other types of filter media are backwashed or cleaned at the frequency specified by the manufacturer.


  
6.3.1.2.1: Ensure that the whirlpool spa water is changed daily.


  
6.3.2.1.1: Ensure that the free residual halogen is increased to at least 10.0 mg/L (ppm) in whirlpool spas and circulated for at least 1 hour at the end of each day.


  
6.3.2.1.2: Increase the free residual halogen to at least 10.0 mg/L (ppm) and circulate for at least 1 hour every 24 hours. Test the free residual halogen both at the start and completion of shock halogenation. Superhalogenate the water in the entire RWF system to 10 ppm to include the whirlpool spa/spa pool tub, compensation tank, filter housing, and all associated piping before starting the 1-hour timing.


  
6.4.1.2.2: Ensure that anti-vortex drain covers are provided on swimming pools and whirlpool spas.


  
6.4.1.3.1: Ensure that children in diapers or who are not toilet trained are not permitted in the public swimming pools and whirlpool spas.


  
6.7.1.1.1: Provide safety signs for all RWFs, except for baby-only water facilities. Ensure the signs, at a minimum, include the following words: (1) do not use these facilities if you are experiencing diarrhea, vomiting, or fever; (2) no children in diapers or who are not toilet trained; (3) shower before entering the facility; and (4) bather load #. For children?s RWF signs, include the exact wording ?TAKE CHILDREN ON FREQUENT BATHROOM BREAKS? or ?TAKE CHILDREN ON FREQUENT TOILET BREAKS.?


  
6.8.1: Prohibit children in diapers or who are not toilet trained from using any RWF that is not specifically designed and approved for use by children in diapers.


  
6.8.1.1.1: Provide safety signs for all RWFs, except for baby-only water facilities. Ensure the signs, at a minimum, include the following words: (1) do not use these facilities if you are experiencing diarrhea, vomiting, or fever; (2) no children in diapers or who are not toilet trained; (3) shower before entering the facility; and (4) bather load #. For children?s RWF signs, include the exact wording ?TAKE CHILDREN ON FREQUENT BATHROOM BREAKS? or ?TAKE CHILDREN ON FREQUENT TOILET BREAKS.?
