Compilation of Rules and Regulations of the State of Georgia › Department 511 - RULES OF GEORGIA DEPARTMENT OF PUBLIC HEALTH › Chapter 511-3 - ENVIRONMENTAL HEALTH HAZARDS › Subject 511-3-5 - PUBLIC SWIMMING POOLS, SPAS, AND RECREATIONAL WATER PARKS › Rule 511-3-5-.07 - Circulation Systems

Current through Rules and Regulations filed through June 27, 2024
(1)
				A circulation system consisting of pumps, piping, return inlets and suction
				outlets, filters and other necessary equipment shall be provided for complete
				circulation of water through all parts of the pool.
(a) The equipment for a swimming pool shall
				be of adequate size to turn over the entire pool water capacity. The turnover
				rate for pools constructed after the adoption of this chapter shall not exceed
				the sum of one and one-half times the average water depth in feet; where the
				number of hours is equal to the number feet calculated, or exceed once every
				six hours whichever is less. Unless the rate is otherwise specified in
				subsection (b) below. This system shall be designed to give the proper turnover
				rate based on the manufacturer's recommended maximum pressure flow of the
				filter in dirty media condition of the filter, immediately prior to cleaning
				the filter.
(b) Turnover rates for
				pools by type listed below:
Type
Turnover Rate
1. Activity Pools
2 hours
2. Continuous Water Channels
1 hours
3. Dual Use Swimming Pools (swimming pools with a
								water slide and/or one other feature with an average depth exceeding 24 inches)
4 hours
4. Diving Pools
8 hours
5. Interactive Water Play Pools/Spray Pads
30 minutes
6. Landing Pools, Flumes, Slides and All Other
								Plunge Pools

(c)
				Timing devices will be allowed for the purpose of turning down the circulation
				system during times when a pool is not being used. Timing devices must be set
				to provide at least one complete turnover immediately prior to the pool
				reopening.
1. The system flowrate shall not
				be reduced more than 25% lower than the minimum design flowrate requirement and
				only reduced when the pool is unoccupied.
2. The system flowrate shall ensure the
				minimum water clarity required under the chapter is met before opening to the
				public.
3. The system shall be
				required to maintain required disinfectant and pH levels at all times.
(d) For spas, a minute
				timer that does not exceed 15 minutes shall be connected to the agitation
				system. The timer shall be located out of reach of a bather in the
				spa.
(e) Water clarity shall be
				maintained. When standing at the pool's edge at the deep end, the main drain
				suction outlet covers or a four inch by four inch square marker tile in
				contrasting color shall be clearly visible. When standing at a spa's edge, the
				deepest portion of the spa floor shall be visible when the water is still.
1. For pools over ten feet deep an eight inch
				by eight inch square marker tile in a contrasting color to the pool floor shall
				be visible at the deepest part of the pool.
2. This reference point shall be visible at
				all times from the edge of the deck.
(f) Circulation system components which
				require replacement or servicing shall be accessible for inspection, repair or
				replacement and shall be installed in accordance with the manufacturer's
				instructions.
(g) Where equipment
				sizing falls within the scope of NSF testing, materials and equipment used in
				the circulation system shall comply with the appropriate requirements of NSF
				Standard 50.
(h) Equipment used for
				a public pool shall be properly supported to prevent damage from misalignment
				or settlement. The equipment shall be mounted so as to minimize the potential
				for the accumulation of debris and moisture, following manufacturer's
				instructions.
