§ 11-11-49. Disinfection equipment.

(a)

All swimming pools shall be provided with approved mechanically operated, positive displacement disinfectant feeding equipment, or other disinfection equipment approved by the director, which:

(1)

shall be in good working order and shall be capable of providing a continuous and effective residual of disinfectant within the swimming pool water 24 hours per day;

(2)

shall have a design feed rate which will provide effective disinfection levels when the swimming pool is in peak demand conditions;

(3)

shall be capable of applying a dose the equivalent to maintain a concentration of at least one ppm free chlorine throughout the swimming pool at all times of operation.

(4)

chlorine generation equipment will only be approved as secondary disinfection unless the chlorine generation equipment is sized to provide a minimum of 2 ppm free chlorine, or enough free chlorine to meet peak demands. Electrolytic generators shall have a TDS or salt (NaCl) readout and a low salt indicator. The feed rate shall be adjustable from zero to full range. The generation unit shall be listed and labeled to UL 1081 by an ANSI-accredited certification organization and shall be interlocked with an automatic means to be disabled. The generator unit(s) shall be installed according to the manufacturer's instructions.

(b)

The use of chlorine gas as a disinfectant is prohibited.

(c)

When the pool water recirculation system is equipped with an automatic chemical control mechanism that continuously analyzes the pool water and automatically activates chemical feeding, a water flow sensing device shall be provided that automatically deactivates all associated chemical feeders when the water flow in the recirculation system ceases.

(d)

When bromine is used as the disinfectant, the following shall be followed:

(1)

Bromine shall be fed on a continuous basis;

(2)

A concentration of at least 4.0—6.0 ppm bromine residual shall be maintained throughout the pool water at all times. A maximum of 10 ppm bromine residual shall be permitted in any swimming pool during use.

(3)

Solid stick or tablet type bromine shall be used with NSF certified commercial feed equipment.

(4)

Erosion feeders shall be equipped with a flow meter. (Ord. No. 4649, 3/13/10, Sec. 1; Ord. No. 5010, 5/14/16, Sec. 1)
