Pool complexes are very popular and attract a large number of people of all ages on a daily basis, and it is very important to maintain and secure the pool area to prevent injury, poisoning or other adverse events. Maintaining hygienic conditions in the pool environment involves conducting daily cleaning, washing and disinfection of the surrounding pool area to reduce the likelihood of microorganisms entering the pool water. Bathers are expected to abide by the rules of conduct at the pool, ie house rules. These are all preventative steps in reducing the risk of injury and / or infection. The analysis of the obtained results of the microbiological cleanliness of the pool environment revealed if the proper treatment is done during hygienic maintenance of the environment. The following microorganisms were tested: aerobic mesophilic bacteria (AMB), enterobacteria (E), yeasts and molds. In periods and locations where significant growth of microorganisms occurred, the reasons for their emergence were identified and steps were proposed to reduce their growth. In order to protect swimmers from pathogens, it is important to maintain the pool environment and disinfect it, as microorganisms can be introduced into pool water, which is the perfect medium for their growth and development. They find food with the help of organic substances that come from the people (no showering, not going through the disinfection points) and from the outside. Therefore, the goal is to provide a healthy place for bathing and recreation for users of all ages.
