The owner or person responsible for the operation of a spa or hot tub shall be knowledgeable in the operation of the equipment, procedures for performing the necessary water quality tests and safety checks and appropriate emergency procedures. The owner shall make available for employees a detailed written manual on the operation and normal maintenance procedures and be responsible for disinfectant and water treatment operations. Unauthorized persons shall not attempt disinfectant and water treatment.
A. 
Water quality. The water used at all spa pools shall meet the bacteriological, chemical, physical and radiological standards of this chapter.
B. 
Circulation. Water shall be introduced to and withdrawn from the pool so as to provide uniform circulation and uniform disinfectant residual throughout the entire spa pool.
C. 
Recirculation and filtration. Spa pools shall be provided with a recirculation and filtration system, except where there is a flow of water of the quality and quantity through the spa pool which at all times conforms to the provisions of this chapter.
D. 
Clarity of the pool. All water in the spa pool shall be sufficiently clear to permit a black disc, six inches in diameter on a white field, when placed on the bottom of the pool at the deepest point, to be clearly visible.
E. 
Contamination. Water in a spa pool shall be considered contaminated when one of the following conditions exist:
(1) 
More than one ten-milliliter portion of any sample shows a positive test for coliform organisms, when multitube fermentation technique is used, or more than one coliform per 50 milliliters, when the membrane filter test is used.
(2) 
Two consecutive samples show in a positive test for coliform organisms in any ten-milliliter portion of any sample, when the multitube fermentation technique is used, or more than one coliform per 50 milliliters, when the membrane filter is used.
(3) 
Two of any 10 consecutive samples show a positive test for coliform organisms in any of the ten-milliliter portions of any sample, when the multitube fermentation technique is used, or more than one coliform per 50 milliliters, when the membrane filter test is used.
(4) 
When any harmful level of disease-producing organisms, toxic chemicals or adverse physical conditions are present in the water.
F. 
Laboratory testing. Laboratory tests of water shall be performed by competent personnel in accordance with the procedure provided in the current edition of Standard Methods for the Examination of Water and Wastewater, published jointly by the American Public Health Association and the American Water Works Association. Conformity with these standards shall be evidenced by a statement from the laboratory to such effect. Upon notification by the laboratory that water does not meet standards for safe and sanitary pool water, the spa pool shall be immediately closed to the public until the problem has been corrected. Upon receipt of such notification, the owner shall also provide notification to the Community Development Department. This procedure shall be documented on the daily records indicating the corrective action taken.
G. 
Turnover period. Spa pools and hot tubs must be capable of minimum turnover rates of 30 minutes.
H. 
Cleaning and refilling. Spa pools shall be emptied and cleaned as often as necessary. The time will be directly related to the length of time the pool is in operation and the number of people using it.
I. 
Disinfection. When chlorine or a hypochlorite compound is used for disinfection, the free chlorine residual in the water of the spa pool shall not be less than two point five (2.5) parts per million. When bromine is used, the minimum residual shall not be less than three point five (3.5) parts per million. The maximum residual for the spa pool may be raised to 10 parts per million or the manufacturer's recommendations (whichever is less). The pH value of the water shall be maintained between seven point two (7.2) and eight point zero (8.0), depending on the amount of free available chlorine or bromine.
J. 
Temperature. Controls shall be provided to prevent water temperatures in excess of 104° F. The controls shall be accessible only to the owner or person responsible for the operation of the spa pool.
K. 
Testing kits and procedures. Testing of water and keeping of records shall be consistent with § 120-12I and J of this chapter, with the exception that pool water shall be tested on an hourly basis.
A. 
A precaution sign shall be mounted adjacent to the entrance to the spa pool or hot tub, containing the following warnings:
(1) 
Prohibition of use by persons under the influence of alcohol or drugs.
(2) 
Caution that persons suffering from heart disease, diabetes or high blood pressure should contact a physician before use.
(3) 
Caution for women who are or may be pregnant to seek the advice of a physician regarding use and to limit the women's time in the pool.
(4) 
Persons should limit the stay in the pool to 15 minutes in any one session.
(5) 
Prohibition of food or drink in the water.
(6) 
Location of the nearest telephone or emergency notification number.
(7) 
Location of an audible emergency alarm to alert others in the area of a need to respond.
(8) 
Not to be operated at water temperatures in excess of 104° F.
B. 
These requirements shall be conveyed by any combination of words, pictures or symbols.
Spa pools and hot tubs shall be located so that they are easily observable by attendants at the facility. At least one attendant shall be proficient in first aid and cardiopulmonary resuscitation as evidenced by current certification by the American Red Cross, YMCA or other equivalent training acceptable to the Department.
