The article examines the interaction of subjects of a two-level hierarchical system. An industrial enterprise discharges wastewater into the river as a result of its work. To prevent the ingress of a large amount of pollutants, water treatment facilities have been installed, the operation of which is regulated by the level of technical support. The state allocates funds to support the activities of the enterprise and regulates the standards for the discharge of pollutants. The interests of both subjects are to maximize their target functional. The article is devoted to the problem of finding optimal control in a mathematical model of water quality management in a dynamic system. Examples of calculations for specific parameters are given. Based on the examples given, we can draw conclusions about the influence of parameters on the system. The type of the emitted substance has the greatest influence on the system, namely the values of such parameters as the initial concentration and the coefficient of non-conservativeness. With long-term interaction, the speed of self-cleaning of the river plays a significant role. At a low level of self-purification of the river, the concentration of substances in the river almost reaches the maximum permissible level. The deterioration of the environmental situation leads to losses on the part of the Host. The reverse situation allows us to continue cooperation in the future, while receiving a greater gain. Also, the winnings of the subjects significantly depend on the volume of investments.
