18-29-1204.4.10.1 Water recirculation system outlets.

   If the pool width does not exceed 20 feet (6096 mm), water recirculation system outlets shall be so located as to provide at least one outlet at the deepest point of the pool. If the pool width is more than 20 feet (6096 mm), multiple outlets shall be provided and spaced not more than 20 feet (6096 mm) apart, nor more than 10 feet (3048 mm) from the walls. All pool drain outlets shall be equipped with gratings having an area of openings not less than 10 times the cross-sectional area of the outlet pipe. The grating shall be designed such that it cannot be readily removed by bathers and will not injure bather’s fingers.

(Added Coun. J. 10-14-21, p. 37722, Art. XII, §1)

18-29-1204.4.10.2 Drainage system.

   Pools shall be equipped with facilities for completely emptying the pool and the discharge from the pool water to the sewer shall be at a rate not exceeding 250 gallons per minute (15.8 L/s). No direct connection shall be made to the sewer. The drainage system shall be constructed in conformance with Article 7. The drain pipe diameter shall be at least 6 inches (150 mm).

(Added Coun. J. 10-14-21, p. 37722, Art. XII, §1)

18-29-1204.4.10.3 Drain water discharge.

   Drain pipe lines from the pool deck, scum gutters and pools shall discharge into a common catch basin. If elevation permits, the catch basin may drain by gravity into the sewer. If, however, the elevations are such as to require pumping, the combined discharge shall be pumped into the sewer. In either case, a back water valve or gate shall be installed downstream from the catch basin and the pump. Water drained from the pool shall not be discharged to the sewer system during periods of rain or storms. At no time shall the rate of drain water discharge exceed 250 gallons per minute (15.8 L/s).

(Added Coun. J. 10-14-21, p. 37722, Art. XII, §1)

18-29-1204.4.11 Recirculation system and appurtenances.

   Recirculation systems and appurtenances shall comply with the standards specified in Sections 18-29-1204.4.11.1 through 18-29-1204.4.11.8.

(Added Coun. J. 10-14-21, p. 37722, Art. XII, §1)

18-29-1204.4.11.1 Required apparatuses.

   The recirculation system shall consist of pumping equipment, hair and lint catchers and filters, together with the necessary pipe connections to the pool inlets and outlets, facilities and pipe connections necessary for backwashing filters, and facilities and equipment for disinfecting the pool water.

(Added Coun. J. 10-14-21, p. 37722, Art. XII, §1)

18-29-1204.4.11.2 Water volume turnover.

   The recirculating system shall be capable of producing a six-hour turnover of the entire water volume contents.

(Added Coun. J. 10-14-21, p. 37722, Art. XII, §1)

18-29-1204.4.11.3 Pump capacity.

   The recirculation system pump shall have sufficient capacity to discharge the volume of water required for a six-hour turnover of the pool against the maximum head in the recirculating system.

(Added Coun. J. 10-14-21, p. 37722, Art. XII, §1)

18-29-1204.4.11.4 Backwash filter rate.

   The pump used for backwashing filters shall have sufficient capacity to provide a rate of at least 15 gallons per minute per square foot (10 L/s/m2) of filter area.

(Added Coun. J. 10-14-21, p. 37722, Art. XII, §1)
