1. (1) The manager shall ensure that:

   1. (a) a pool with a surface area greater than 3,500 square feet has an overflow gutter system; and
   2. (b) a pool with a surface area equal to or less than 3,500 square feet has an overflow gutter system or one or more skimmers.
2. (2) Subsection (1)(a) does not apply to any pool in which sufficient skimming of the pool is demonstrated to a local health officer by a licensed design professional.

3. (3) If the pool has an overflow gutter system, the manager shall ensure that the overflow gutter system:

   1. (a) except as described in Subsection (4), extends completely around the pool perimeter;
   2. (b) ensures continuous uniform skimming of the pool water;
   3. (c) is capable of continuously removing pool water at 100% of the maximum flow rate;

   4. (d) is connected to the circulation system by a surge system that:

      1. (i) has a surge capacity of no less than one gallon for each square foot of surface area;
      2. (ii) has water level sensors and controls built in to maintain the pool water level; and
      3. (iii) promotes continuous skimming in each surge condition; and

   5. (e) is designed and constructed:

      1. (i) to prevent entrapment of any part of a bather's body;

      2. (ii) with the opening into the gutter system beneath the coping or grating that:

         1. (A) is at least three inches in height; and
         2. (B) has a depth of at least three inches;
      3. (iii) with a handhold as described in Subsection R392-302-16(2);
      4. (iv) with outlet pipes that are at least two inches in diameter; and
      5. (v) with the total combined area of all unobstructed openings in the outlet grates being equal to or greater than a minimum of 1-1/2 times the total cross-sectional area of all connected suction outlet pipes.

4. (4) Gaps in the pool perimeter overflow gutter system requirement described in Subsection (3)(a) are allowed for a pool with design features such as stairs, recessed steps, ladders, or shared walls between two separate pools if:

   1. (a) the manager can demonstrate compliance with Subsections (3)(b) through (3)(e); and
   2. (b) any overflow gutter system gap does not extend more than 15 continuous feet.

5. (5) If the pool has a skimmer, the manager shall ensure that each skimmer:

   1. (a) complies with NSF/ANSI/CAN 50-2021 Equipment and Chemicals for Swimming Pools, Spas, Hot Tubs, and Other Recreational Water Facilities;
   2. (b) is installed on any pool with a surface area equal to or less than 3,500 square feet;
   3. (c) has at least one skimming device provided for each 500 square feet of water surface area or fraction thereof, except as provided in Subsections R392-302-37(1)(g) and R392-302-43(2)(e);
   4. (d) is spaced to provide an effective skimming action over the entire surface of the pool if two or more skimmers are required;
   5. (e) is installed with the normal operating level of the pool water at the midpoint of the skimmer opening or in accordance with the manufacturer's instructions;
   6. (f) is built into the pool wall;
   7. (g) has piping and other components that are designed for a total capacity of at least 80% of the maximum flow rate of the circulation system;

   8. (h) is designed with a minimum flow rate of 25 gallons per minute and a maximum flow rate of 55 gallons per minute; and

      1. (i) is equipped with a weir that:
      2. (i) is maintained properly for continuous skimming of the surface water;
      3. (ii) moves freely and automatically adjusts to variations in water level over a range of at least four inches; and
      4. (iii) operates at any flow variation.
6. (6) A higher maximum flow rate through a skimmer up to the skimmer's NSF rating is allowed if the manager can demonstrate to the local health officer, through a licensed design professional, that the piping system is designed to accommodate the higher flow rate.

7. (7) The manager shall ensure that an easily removable and cleanable basket or screen through which any overflow water passes:

   1. (a) is provided to trap large solids;
   2. (b) is maintained in good working condition;
   3. (c) does not allow disinfection products to be stored or circulated; and
   4. (d) is emptied as often as necessary to prevent clogging and buildup of potentially infectious debris.

8. (8) The manager shall ensure that if an equalizer pipe is used to prevent air-lock, the equalizer pipe is:

   1. (a) sized to meet the capacity requirements for the filter and pump;
   2. (b) not less than two inches in diameter;
   3. (c) designed to control velocity through the pipe in accordance with Subsection R392-302-19(3)(b)(ii);
   4. (d) located at least one foot below a valve or float assembly that prevents suction from the equalizer pipe under normal operating conditions;
   5. (e) protected with a cover or grate that meets the requirements of ANSI/APSP/ICC-16 2017, American National Standard for Suction Outlet Fitting Assemblies (SOFA) for Use in Pools, Spas, and Hot Tubs along with the provisional amendment approved on March 19, 2021; and
   6. (f) sized to accommodate the design flow requirements described in Subsection (4).
9. (9) The manager shall maintain proper operation of each valve and float assembly.
