Water is an indispensable raw material for ensuring the life of people, animals and all living things. Once in the body, it helps absorb nutrients, regulate body temperature, and remove toxins, but in order not to cause harm, it must clearly meet quality and safety standards. The important thing is that contaminated tap water becomes poison for the body. Compliance of water with sanitary and chemical indicators of quality is one of the main factors of successful breeding of productive animals. Numerous classes of pathogens entering the environment with human and animal excreta are causative agents of infectious diseases. All of them have a pronounced resistance in the water environment to most disinfectants. The infectious dose of viral agents and protozoa is lower than that of bacteria: in the range of one to ten infectious units or oocysts. At least 2 billion people in the world use a source of drinking water contaminated with feces. Contaminated water can be a factor in the transfer of pathogens of such diseases as: diarrhea, cholera, dysentery, typhoid and poliomyelitis. Drinking water contaminated with pathogens is responsible for 485,000 deaths worldwide every year. In developing countries, 22% of medical facilities do not have water supply, 21% do not have sanitation services, and 22% do not have waste management services. In order to study the methods of water disinfection, in particular the effectiveness of using a hypochlorite plant in productive animal husbandry, we conducted bacteriological studies of water safety. To compare indicators, sampling was carried out before starting the hypochlorite plant and during its operation. As a result of the research, it was found that using a hypochlorite unit, it is possible to successfully remove biological agents from water, obtaining water that meets sanitary and hygienic requirements.
