IntroductionThe objective of swimming pool inspection is to protect public health and safety by ensuring that swimming pools are maintained and operated in accordance with regulations. There are many different aspects of the pool that need to be checked to ensure its safety, not only the water quality, but also the areas around the pool, including the equipment, recirculation system, etc. Routine pool inspections allow operators and inspectors to identify potential problems that require repairs or adjustments to prevent accidents from occurring. Water Quality Proper water chemistry is essential to maintaining safe pool operation. Water chemistry usually includes five broad factors: pH, free available chlorine, combined available chlorine, total alkalinity, and calcium hardness. Excessive or inadequate levels of any water chemistry would cause cloudiness, irritation, corrosion or even health risks for swimmers. Additionally, improper pool water balance can damage filter and piping systems. The pool water was very clear and the pool drain could be clearly seen by standing at the edge of the pool at the deepest part. The pool water level was kept exactly above the skimmers. Liquid sodium hypochloride was used as a disinfectant. Water chemistry was tested using the Taylor test kit. The results were as follows: pH 7.5 Free Available Chlorine 2.5 ppm Total Available Chlorine 3.0 ppm Combined Chlorine 0.5 ppm Hardness 210 ppm Total Alkalinity 60 ppm Temperature 84 F According to section 75 pool regulations, the Chlorine residual must be kept above 0.5 ppm when the pH is between 7.4 and 7.8. The water temperature should not be higher than 98F.

Regular and accurate testing of pool water prevents long-term problems such as corrosion, scaling or user complaints. The operator was trained by the previous operator and had not previously received any professional training. According to section 81 of the legislation, “the Department of Health may require a certificate of competence obtained through attendance and successful completion of approved swimming pool operator training courses as evidence of compliance with this section”. Although it is not mandatory, it is recommended that the operator obtain professional training to best maintain the pool. Knowing the basic knowledge, techniques and skills of swimming pool operation will save the operator a lot of time and money in pool care.
