"Section 18-10-2. Regulations. 1. Each public swimming and wading pool operating in the city of Salt Lake shall be under the supervision of a competent manager or operator who shall have the responsibility of effecting full compliance with these regulations. 2. All parts of each public swimming and wading pool, including the premises, equipment and appurtenances, shall be maintained and operated with strict regard to the safety and health of bathers and - 2 - operating personnel. 3. All parts of each public swimming and wading pool, includ- ing the premises and appurtenances, shall, at all times while the pool is open to the public, be maintained in a clean and sanitary condition. 4. All patrons of the pool shall be required to take a cleansing shower bath before entering the pool. 5. Persons obviously afflicted with a communicable disease or infection shall be excluded from the pool. 6. Common towels, combs, brushes and drinking cups are pro- hibited. 7. All bathing suits, towels and bathing caps furnished patrons at the pool shall be laundered, disinfected, and dried in a I( manner approved by the State Department of Health. 8. Bath house floors and appurtenances, as well as pool decks, shall be scrubied at least once a day or at sufficiently frequent int- ervals to insure cleanliness at all times. Disinfection with chlorine or other germicide approved by the Salt Lake City Department of Health shall be accomplished regularly. 9. The water contained in each public swimming and wading pool shall conform to the following requirements: (a) Not more than 15% of the samples collected from the pool during any period of 30 or more consecutive days shall contain more than 200 bacteria per ml. as counted on standard nutrient agar or shall show positive test (confirmed test) in any of five 10 ml. portions.

Only those samples collected while the pool is occupied by bathers shall be considered in determination of water quality. (b) At all times while the pool is in use, water clarity shall be such that a disc 2 inches in diameter which is divied into quadrants in alternate colors of red and black shall be clearly discernable through 15 feet of water and the different colors readily distinguishable. (c) The water shall at no time while the pool is in use contain residual chlorine at any point in excess of 0.75 p.p.m. Water treated by the chlorine-ammonia process shall at no time while the pool is in use contain residual chloramine at any point in excess of 1.0 p.p.m. Chlorine residuals shall be kept above 0.35 p.p.m. at all times, and chloramine residuals shall be kept above 0.5 p.p.m. at all times. This regulation is not intended to prohibit the use of free chlorine residuals in excess of the limits stated above in pools operated by a person who has demonstrated ability to successfully disinfect the water by this means. 10. At least two water samples shall be mi lected weekly from each pool while it is in use and shall be submitted to a laboratory approved by the Salt Lake City Department of Health. Analyses shall be completed as described in regulation 9 (a), above, and reported promptly by the pool manager to the Salt Lake City Department of Health. Such samples may be submitted to Utah State Department of Health Laboratories for analysis if desired. - 3 - 11, A written record shall be kept of all information per- tinent to proper operation,imaintenance and sanitation of each pool and its equipment and appurtenances, and shall be submitted at weekly intervals to the Salt Lake City Department of Health. This record shall include chlorine residual in the pool water, pH and temperature of the pool water, pool recirculation rate, quantities of chemicals and/or filter aid used, filter head loss, filter washing schedule, cleaning and disinfecting schedule for pool decks and bath house, bather load, and such other informa- tion as may be required by the Salt Lake City Board of Health_ / e',t, e' 12. Drinking water made available to pool patrons shall be drawn from a public water supply or from any other source approved by the Salt Lake City Department of Health. 13. Interconnections or other plumbing features which might give rise to contamination of a public water supply or other,water supply by back-siphonage or otherwise are prohibited. 14. Toilet and shower wastes from bath houses shall be dis- charged into public sewers or into an approved and properly operating sewage disposal unit 15. Liquid discharges not covered in regulation 14 above shall conform to the requirements of the Utah Water Pollution Control Board. "Section 18-10-3. Design and Construction. 1. Pools shall be constructed of smooth, impervious paterial, preferably concrete, and shall have vertical walls. 2, Slope of the pool floor shall not exceed one foot verti- cal in 15 feet horizontal in the shallow portion of the pool, except that this standard may be modified for pools having a water Surface area of less than 800 square feet. Depth of waterin diving areas shall be at least 8 feet, and in cases where diving boards or platforms are elevated 8 feet or more above the water surface, such depth shall be at least 10 feet. 3. A concrete walkway at least 4 or more feet wide shall completely encircle the pool, and the surface shall be slightly roughened to minimize danger of slipping. Adequate drainage facilities must be provided for the walkway. 4. Stirs, ladders, or step holes,HII.th hand rails, shall be provided near each corner of the pool, except that such appurtenances will not be required at the shallow end of the pool if the distance from the pool floor to the walkway at that point is 2 feet or less. For pools hav- ing less than 800 square feet of water surface area, one ladder at each end may be acceptable. 5. Any step holes provided shall be of such design as to permit easy cleaning, and shall be so designed as to drain into the pool. 6. A man-proof fence or other barrier at least 6 feet in height shall completely encircle the pool area, except that in the case of hotel or motel pools modifications are permissible in consideration of architectural and lantscaping requirements, provided the barrier is not less than 3 feet high and provided further it adequately fulfills the function of excluding all spectators from the pool enclosure. 7. Bath houses shall be considered as an essential part of the swimming pool facility, and they shall be so located that bathers leav- ing the bath house will enter the pool area near the shallow end. Bath houses shall be so designed that bathers must pass toilets and showers before entering the pool area. Bath house facilities need not be provided for separate wading pools nor for hotel and motel swimming or wading pools - 4 - in cases where only those persons who have rented rooms in said hotel or motel are permitted in the pool. 8. Adequate toilets and showers must be provided to serve the maximum number of bathers expected to patronize the pool at any time. Means shall be provided for heating shower water. The bathing load shall be estimated on the basis of 30 square feet of combined pool and deck area per bather. This requirement will be deemed to have been satisfied in the case of hotel and motel pools if adequate toilet and showering facilities are available to each patron of said hotel or motel. 9. Bath house floors shall be constructed of impervious material, preferably slightly roughened, and shall be adequately pitched to floor drains. Design of bath house appurtenances and of floor drains shall be such as to insure easy flushing of the entire bath house floor, and quick removal of any water reaching the floor. 10. Sand lots and grass areas shall not be included within the pool enclosure unless bathers are forced to pass through a continuous- flow cleansing shower and foot washer before returning to the pool from such areas. 11. Adequate facilities shall be provided, in connection with the pool, for use of spectators. This should include toilet facilities. Design must be such as to exclude spectators from the bath house and pool enclosure. 12. Pools shall be provided with complete recirculation equip- ment, consisting of pump, motor, filters, chlorinator, and necessary appurtenances, as outlined in the following paragraphs. 13. In the case of flowing-through pools, the filter require- ment included in Paragraph 12 (above) may be waived, provided the pool water supply meets turbidity requirements and is compatible with approved germicidal treatment. 14. Sand filters and pressure diatomaceous earth filters shall be designed for a filter rate of not to exceed 3 gallons perminute per square foot of net filtering surface. This rate shall be 2-1/4 gal- lons per minute per square foot of net filtering surface for gravity (vacuum) diatomite filters. Filtering capacity shall be based on the combined flow necessary to provide a turnover of total pool volume in a maximum of 8 hours plus a turnover of wading pool volume in a maximum of 4 hours, plus additional requiements for amitinuous showers at entrances to sand or grass areas and other continuous flows such as for foot washers. 15. Sand filter underdrains shall be designed to provide equal distribution of wash water. Specially designed units of proved adequacy, such as "Wheeler" bottoms, will be accepted. Pipe underdrain systems shall consist of a central manifold and laterals with drilled orifices. The ratio of total area of all orifices to sand bed area shall not exceed 0.003. Total cross-sectional area of all latemis shall be at least twice the total area of all orifices and the cross-sectional area of the manifold shall be at least 1-1/2 times (preferably 2 times) the total cross-sectional area of all laterals. Otifices in the manifold shall be drilled along the top and provided with umbrella strainers. All other orifices shall be drilled on the underside of laterals. Orifice and lateral spacing shall be about equal, and variations from nominal orifice spacing shall not exceed 3/4 inches. If the manifold size is larger than the piping to which it connects outside the filters, reducers shall be used for the transition. 16. (a) Gravel supporting the sand bed in sand filters shall consist of at least 4 layers, suitably graded from a coarse size of 2-1/2 inches to a minimum size of not more than 3/32 inch, with a depth of not less than 12 inches above strainers. The bottom course shall extend above - 5 - the top of laterals or strainer nozzles. Gravel shall consist of hard rounded particles. (b) Filter sand should consist preferably of clean silica grains and the sand bed shall be at least 24 inches deep. Effec- tive size shall be between 0.35 millimeter and 0.55 millimeter and th+uniformity coefficient shall not exceed 1.7: It is desirable to support the filter sand on a 3 inch layer of torpedo sand having an effective size between 0.8 millimeter and 2 milli- meters and as uniformity coefficient of not more than 1.7. 17. Wash water troughs for gravity filters shall be designed to handle the full wash water flow of 15 gallons perminute per square foot of filter surface area without submergence. The lip of the trough (or normal operating water level in the case of gravity vacuum diatomite filters) shall be at least 36 inches below the pool overflow trough lip or such other distance as is necessary to insure delivery of full filtra- tion flow to the filter either through the overflow trough drainage system or through the main pool drain with water standing 6 inches over the wash water trough lip. Troughs shall be so spaced that each trough serves the same filter surface area and so that maximum horizontal tralel of wash water to trough lip does not exceed 3 feet. Troughs shall beset far enough above the sand surface to provide a free space between trough bottom and sand surface of at least one-half the sand bed depth. In pressure filters a pipe may be used in lieu of a wash water trough pro- vided that full cross-sectional area of the filter shell is maintained for a distance above the sand surface equal to at least one-half the sand depth, with the outlet pipe placed above this point, a sufficient distance to insure low lateral velocities of wash water. 18. Sand filters and appurtenances shall be so designed that a filter wash rate of at least 15 gallons perminute per square foot can be obtained. Drains and sumps shall be sufficiently large to accommodate the maximum wash water flow without surcharge. 19. Diatomaceous earth filters shall be so designed that elements can be hosed down during each washing cycle. Any design which provides the equivalent in washing effectiveness will be acceptable. Where necessary, a hose bibb shall be provided in the vicinity of the filter to facilitate the washing operation. 20. Diatomaceous earth filter installations shall be so designede.l that water can be recircuIted through pumps and filtering units or through filters to waste during the pre-coating process, and so that each filter unit can be pre-coated individually. 21. Diatomaceous earth filters shall be provided with posi- tive displacement type slurry feeders capable of delivering diatomaceous earth body feed at a rate of at least two ounces per square foot of filter surface area during each 24 hours. 22. The filter room shall be readily accessible to the pool proper so that all recirculation equipment, can be sups'vised easily by the pool operator. Sufficient floor space ;shall be provided to permit free access to all equipment. 23. Gravity (vacuum) filters shall be so designed that the pool operator can conveniently observe the filter bed surface at any time. 24. Rate-of-flow indicators shall be provided at all pools for measurement of both recirculation rates and filter washing rates, with a leeway of at least 20% ,qf?both ends of the indicator scale. Dif- ferential producers for such units shall be placed at a suitable distance from fittings, valves, pumps, and`,other flow disturbing influences to assure accuracy of measurements. I - 6 - 25. Suitable loss-of-head gauges shall be provided for measurement of lost head through filters. Properly designed pressure gauges will be acceptable for this purpose. 26. Pools having a water surface area of more than 800 square feet shall be provided with a suitable overflow trough extending around the entire pool periphery. This trough shall be at least 2-1/2 inches wide and 3 inches deep and shall be provided at 10-foot intervals with strainer-equipped drains discharging through 2 inch pipes to a main drain designed to carry a total flow equal to the pool recirculation rate without causing trough submergence. Deck level overflow troughs provided with suitable continuous gratings will be acceptable if hydraulically equiva- lent to the foregoing. 27. In pressure filter installations, the main overflow trough drain shall connect to the recirculation pump suction through a surge tank of suitable capacity which also is fed from the main pool drain line through a suitably designed float-controlled butterflyvalve, or other suitable float valve. High float level (valve closed) shall be at the center line of the main overflow trough drain where it connects to the surge tank, and low float level (valve fully open) shall be the level of the center of the recirculation pump impeller. In gravity filter instal- lations, a similar arrangement shall be provided, except that the filter wash water gullet may be utilized as a surge tank, if desired. Design of these units shall be such as to make possible deliveryof a constant predetermined flow from the main pool drain line to the search tank with the float valve in closed position. ,-z 28. Recirculation pumps shall be capable of delivering the required recirculation flow (see Paragraph 14) at a total dynamic head which includes, in addition to ordinary friction losses, an additional loss of 15 feet for any type of sand filters or for gravity (vacuum) diatomite filters, and 40 feet for pressure diatomite filters, as well as a pool inlet orifice loss of about 15 feet. Pumps to be used for washing end filters shall be capable of delivering a flow of 15 gallons per minute per square foot of filter cell area at the calculated total dynamic head. For pressure filter installations the center of the pump impeller shall be setfer enough below normal pool water level to assure adequate main overflbw trough drain capacity (see Paragraph 26), and adequate delivery of required filtration flow and filter wash water flow through the main pool drain. Pump location shall be kept dry by means of an automatic sump pump, or equivalent. 29. Pools having a water surface area of less than 800 square feet may be provided, in lieu of overflow troughs, with a minimum of two suitably designed skimming devices, each of which shall serve not more than 30 lineal feet of pool periphery and all of which shall discharge through a suitably designed main drain system similar to that specified for overflow troughs. Hydraulic design of this skimming system shall be such as to insure system delivery at a rate not less than the pool recircula- tion rate, with a variation in individual skimmer deliveries of not more than 10%. Wading pools need not be provided with overflow troughs. 30. A chlorinator capable of continuously feeding chlorine to the kecirculation system at various predetermined rates shall be included as part of the pool equipment. Such machines also shall be pro- vided for treatment of the water entering flowing through pools. Maximum chlorinator capacity shall be based on a feeding rate of at least 10 parts per million. Chlorinator injector water supply shall be provided by means of a booster pump fed from the pool recirculation system or from a surge tank supplied with water from the domestic supply system through an air gap. Gas chlorinators shall be installed in a separate room provided with a suitably designed exhaust fan and vent capable of exhausting each three minutes a volume of air( equal to the room volume. Fan switch shall be 114 - 7 - located outside the room, and there shall be on hand in a permanent loca- tion outside the room a suitable gas mask for the use of persons finding it necessary to work in a gas-laden atmosphere. 31. A suitable means of introducing filter alum (or other coagulant or filter aid) and soda ash (or other alkalinity-producing chemi- cal) shall be provided. Flowing-through pools need not be equipped with such devices unless filtration of the water is necessary for compliance with water quality standards. 32. Suitable testing equipment, in good repair, for determina- tion of hydrogenion concentration (pH) and chlorine residual shall be provided. 33. Vacuum cleaner equipment for removing sediment from the pool floor shall be provided. Recirculation piping shall include suitable connections for this equipment, or a portable, self-contained cleaner, com- plete with pump, shall be provided. It is suggested that the portable, self-contained unit be provided for all pools designed with diatomaceous earth filter systems, and if this is done, adequate drainage piping must be provided to receive the vacuum cleaner discharge. 34. Hydraulically balanced multiple inlet orifices shall>be provided for introduction of treated water to the pool in such a manner as to insure its complete distribution throughaut the entire pool volume. Only easily removable, non-adjustable orifice inlets will be approved. A spacing of 10 feet or less between inlets will be acceptable. Inlets shall be located in the pool wall near the floor, with discharge horizon- tally and perpendicular to the vertical portion of the wall. In pools having a large-radius fillet between pool wall and pool floor, inlets shall be placed at the mid-point of the arc section connecting wall and floor, and shall discharge horizontally as described above. Inlets will be considered to be suitably balanced if maximum variation in flow between any two orifices is less than 10 percent. One method of accomplish- ing this is to design orifices for a head loss of 15 feet and limit friction losses in inlet piping which must form a complete loop around the pool, $O 2-1/2 feet, based on normal recirculation rate. For pools having a water surface area of less than 800 square feet, and for wading pools, the required number of inlets may be subject to modification where jxstification can be shown. 35. A suitable factor of safety shall be allowed in design of main pool outlet drain line to insure free flow of pool water to filter, based on the total recirculation rate, or the filter wash rate, whichever is larger. 36. Total area of openings in outlet gratings shall be such as to result in a velocity of flow through the openings not to exceed 1-1/2 feet per second at pool recirculation flow. 37. Physical connections between the pool recirculation system and any public water system are prohibited. For pressure filter installa- tions, discharge of filter wash water to sewers shall be accomplished through a trapped sump which will provide a suitable air gap between pool recirculation piping and sump overflow level. Sump discharge line shall have adequate capacity to carry the full filter wash water flow. 38. Toilet and shower wastes from bath houses shall be dis- charged into public sewers or into an approved individual sewage disposal unit such as a properly designed septic tank and sub-surface drainage field. Plans for bath house construction shall show complete details of sewage disposal design in cases where such units are necessary. 39. Foot baths are prohibited. _ 8 - 40. Circulating foot washers are optional. If foot- washers are installed at any entrances to swimming pools, they shall have minimum horizontal dimensions of 4 feet and shall extend at least 1 foot beyond entrance-way gate posts. They shall be provided with about 5 gallons per minute of flow from the pool recirculation system, through two suitably designed orifices set in one wall and discharging at right angles thereto. An overflow outlet shall be so designed as to maintain a water depth of two inches to three inches, with discharge to pool overflow trough drainage system. A valved drain to waste or to overflow trough main drain shall be provided at the low point in the foot washer. 41. All features of the design of the pool and its appurten- ances which may result in intermittent or regular liquid discharges to any water course shall meet all requirements of the Utah Water Pollution Control Board. "Section 18-10-4. Exceptions for wading Pools. 1. Wading pools shall be governed by the foregoing standards except for the following modifications: (a) Bath house facilities will not be required for any wading pool not part of a swimming pool. (b) Overflow gutters will not be required for wading pools. (c) Vacuum cleaning equipment will not be required for any wading pool not part of a swimming pool, but all wading pools must be so designed as to permit frequent draining and flushing. (d) Wading pool overflow or recirculation flow may be discharged to an adequately designed swimming pool overflow trough drainage system, but not directly into the swim- ming pool. "Section 18-10-5. Safety Prov sions. 1. The following safety requirements shall be maintained, ' 1 pools and all parts of swimming pools, including their premises and appurtenances, be designed, maintained and operated with strict regard to the safety of bathers and operating personnel. (.fie) An adequate number of lifeguards shall be on duty in the pool area at all times when the pool is open to bathers; also, that one or more elevated life guard chairs be provided to permit unobstructed view of the total pool water area by lifeguards. (6) At least one throwing ring-buoy, attached to a 1/4- inch line equal in length to the pool width be kept at a con- venient point in the pool area at all times when the pool is open to bathers. (d) Ropes equipped with floats be extended across the pool at the 5-foot depth, and at any shallower depth where slope of the pool floor changes or where pool depth changes abruptly. (A ) Easily read water depth markings be provided at suitable intervals on the deck or on the pool walls above the water line. ( Lighting facilities, either natural or artificial be such t at all parts of the pool floor can be seen easily from the deck at all times when the pool is open to bathers. ) Diving boards and towers, when provided, be rigidly con- structed and securely anchored, and covered with non-slip material. - 9 - (4) No diving board or platform which is elevated more than 10 feet above the pool water level be made available for general public use.
