The Model Aquatic Health Code

Detailed scaled and dimensional drawings for each AQUATIC FACILITY shall show the location and number of all available HYGIENE FACILITIES provided including dressing rooms, lockers and basket STORAGE, showers, lavatory, toilet fixtures, and DIAPER-CHANGING STATIONS.

Technical specifications for the construction of each AQUATIC VENUE and all appurtenances shall accompany the drawings for the AQUATIC FACILITY plans.

The technical specifications for each AQUATIC FACILITY and each AQUATIC VENUE shall include all construction details not shown on the plans that relate to the AQUATIC FACILITY.

The technical specifications for each AQUATIC FACILITY shall include the sources of all water supplies.

Technical specifications shall include the water surface area and volume of each AQUATIC VENUE and associated water features, if applicable.

The technical specifications for each AQUATIC FACILITY and each AQUATIC VENUE shall include THEORETICAL PEAK OCCUPANCY, respectively.

The THEORETICAL PEAK OCCUPANCY for an AQUATIC VENUE shall be used for designing systems that serve BATHERS and PATRONS. (Note: The specified density factors are the lower limits for determining THEORETICAL PEAK OCCUPANCY.)

The THEORETICAL PEAK OCCUPANCY for an AQUATIC FACILITY shall be used for designing systems that serve BATHERS and PATRONS and shall incorporate non-water related areas such as DECKS and other adjacent portions of the AQUATIC FACILITY not associated with the AQUATIC VENUE.

The THEORETICAL PEAK OCCUPANCY shall be calculated by dividing the surface area in square feet of the AQUATIC VENUE by the density factor (D) that fits the specific AQUATIC VENUE being considered. THEORETICAL PEAK OCCUPANCY = AQUATIC VENUE surface area / D The density factors (D) are: Water/bather-related: 1) FLAT WATER density factor = 20 ft2 (1.9 m2) per BATHER. 2) AGITATED WATER density factor = 15 ft2 (1.4 m2) per BATHER. 3) HOT WATER density factor = 10 ft2 (0.9 m2) per BATHER. 4) WATERSLIDE LANDING POOL density factor = manufacturer-established capacity at any given time. 5) INTERACTIVE WATER PLAY water density factor = 10 ft2 (0.9 m2) per BATHER on surface. Non-water/PATRON-related 6) DECK density factor = 50 ft2 (4.6 m2) per BATHER. 7) Stadium seating density factor = 6.6 ft2 (0.6 m2) per BATHER.

The density factors in MAHC Section 4.1.2.3.5.3 may be modified for higher BATHER or PATRON density, but they shall not be modified to be lower than the density factors listed in MAHC Section 4.1.2.3.5.3.

The THEORETICAL PEAK OCCUPANCY for an AQUATIC FACILITY shall be determined by adding the calculations for each AQUATIC VENUE in the AQUATIC FACILITY.

The technical specifications and supplemental engineering data for each AQUATIC FACILITY and each AQUATIC VENUE shall include: 1) Detailed information on the type, size, operating characteristics, and rating of all mechanical and electrical equipment; 2) Hydraulic computations for head loss in all piping and recirculation equipment; and 3) Pump curves that demonstrate that the selected recirculation pump(s) are adequate for the calculated required flows.

The technical specifications for each AQUATIC VENUE shall include the recirculation rate and TURNOVER time.

The technical specifications for each AQUATIC VENUE shall include information on the filter media such as diatomaceous earth, sand, gravel or other approved material.

The technical specifications for each AQUATIC VENUE shall include information on each piece of equipment associated with that AQUATIC VENUE.

The technical specifications for each AQUATIC FACILITY shall include information on all aquatic SAFETY equipment.

The technical specifications for each AQUATIC FACILITY and each AQUATIC VENUE shall include additional information related to the project requested by the AHJ for the purposes of the construction of the AQUATIC FACILITY and each AQUATIC VENUE and all appurtenances.
