Current through Bulletin 2024-06, March 15, 2024
(1) The manager shall ensure that:
(a) a pool having a surface area greater than
3,500 square feet has an overflow gutter system; and
(b) a pool having a surface area equal to or
less than 3,500 square feet has either an overflow gutter system or a
skimmer.
(2) The local
health officer may allow an exemption to the size requirement for overflow
gutter systems and allow a skimmer system in a pool that has a surface area
greater than 3,500 square feet if sufficient skimming is provided through the
skimmer system.
(3) If the pool has
an overflow gutter system, the manager shall ensure that the overflow gutter
system:
(a) extends completely around the
pool, except at stairs, sloped entries, recessed steps, ladders, or other areas
approved by the local health officer;
(b) is capable of continuously removing pool
water at 100% of the maximum flow rate;
(c) is connected to the circulation system by
a surge system that:
(i) has a surge capacity
of not less than one gallon for each square foot of surface area;
(ii) has water level sensors and controls
built in to maintain the pool water level; and
(iii) promotes continuous skimming in each
surge condition; and
(d)
is designed and constructed:
(i) to prevent
entrapment of any part of a bather's body;
(ii) with the opening into the gutter system
beneath the coping or grating that:
(A) is at
least three inches in height; and
(B) has a depth of at least three inches;
(iii) with a handhold as
described in Subsection
R392-302-16(2);
(iv) with suction outlet pipes that are at
least two inches in diameter; and
(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) If the pool has a skimmer, the manager
shall ensure that each skimmer:
(a) complies
with NSF/ANSI 50-2015 standards, which is incorporated by reference;
(b) is installed on any pool with a surface
area equal to or less than 3,500 square feet;
(c) has at least one skimming device provided
for each 500 square feet of water surface area or fraction thereof;
(d) is spaced to provide an effective
skimming action over the entire surface of the pool if two or more skimmers are
required;
(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;
(f) is built into the pool wall;
(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;
(h) is designed
with a minimum flow rate of 25 gallons per minute, and a maximum flow rate of
55 gallons per minute; and
(i) is
equipped with a weir that:
(i) is maintained
properly for continuous skimming of the surface water;
(ii) moves freely and automatically adjusts
to variations in water level over a range of at least four inches;
and
(iii) operates at any flow
variation.
(j) is
provided with one of the following systems to prevent air-lock:
(i) an equalizer pipe as described in
Subsection (6);
(ii) a surge
system; or
(iii) another system
approved by the local health officer that will assure enough water for pump
suction in the event the pool water drops below the weir level.
(5)
(a) The local health officer may allow a
higher maximum flow rate through a skimmer up to the skimmer's NSF rating if
the piping system is designed to accommodate the higher flow rates;
or
(b) The local health officer may
allow may allow the manager to install a skimmer that is designed with a
minimum of 3.125 gallons to a maximum of 6.875 gallons per linear inch of
weir.
(6) The manager
shall ensure that an easily removable and cleanable basket or screen through
which any overflow water passes:
(a) is
provided to trap large solids;
(b)
is maintained in good working condition; and
(c) is emptied as often as necessary to
prevent clogging and buildup of potentially infectious debris.
(7) The manager shall ensure that
if an equalizer pipe is used to prevent air-lock, the equalizer pipe is:
(a) sized to meet the capacity requirements
for the filter and pump;
(b) not
less than two inches in diameter;
(c) designed to control velocity through the
pipe in accordance with Subsection
R392-302-19(3)(b)(ii);
(d) located at least one foot below a valve
or float assembly that prevents suction from the equalizer pipe under normal
operating conditions;
(e) protected
with a cover or grate that meets the requirements of ANSI/APSP-16 2011, as
incorporated in 16 CFR
1450.3 dated July 5, 2011; and
(f) sized to accommodate the design flow
requirements described in Subsection (3).
(8) The manager shall maintain proper
operation of each valve and float assembly.
