In the modern world, intelligent and digital wastewater disposal systems are increasingly in demand for real-time decision-making on the environmental efficiency of wastewater disposal. The aim of the study is to develop wastewater management processes for monitoring and predicting the parameters of sewerage networks. This paper presents the results of physical modeling of changes in the properties of aqueous solutions transported through the sewerage network to the treatment plant. It was found that the quality of wastewater without additional pollutants is stable, but under the influence of complex, disturbing factors, significant fluctuations in parameters are observed, requiring preventive control to prevent secondary pollution. In order to eliminate the disadvantages of prototypes and improve the environmental safety of wastewater disposal, a conceptual model of digitalization of the wastewater disposal system of water supply and sewerage facilities in the segment "Transport—wastewater treatment" based on the criteria of environmental efficiency of treatment facilities was justified and created. This model for regulating wastewater discharge parameters considers the quality indicators of domestic and industrial wastewater, which excite technological processes at municipal wastewater treatment plants and makes corrections through local treatment methods. This will reduce the risk of secondary pollution and increase management efficiency and environmental compliance of treatment facilities but, at the same time, requires significant investment, infrastructure modernization, qualified personnel and solutions to the issues of integrating processes into a single system. Also, a conceptual scheme of monitoring and forecasting sewerage network parameters and the sequence of sewerage system digitalization using the example of a settlement was created. Further research will be aimed at building a digital system of regulation of water supply and sewerage facilities in the segment based on the criterion of the ecological efficiency of treatment facilities with regard to disturbance.

Introduction. The research is conducted to justify of substantiating scientific foundations for the functioning of electrotechnological wastewater treatment systems of continuous production. Materials and methods. The approaches towards the creation of technical specifications for continuous production are being analyzed, taking into consideration the criteria of energy efficiency. The study is based on the methods of active and passive experiments on pilot plants and industrial equipment, the methods of cross-effects of water purification methods, the methods of the dominant dynamic pollutant, the modeling concept based on the notations of the universal modeling language UML for efficient processing of measurement information. Results and discussion. The architecture of the control system with adaptive adjustment of control strategies in real time is substantiated. The system makes it possible to make decisions under conditions of disturbances of natural and man-made origin, taking into account the criterion of energy efficiency. The generalized system includes: a local control system and a decision subsystem with an input signal filtering unit (the decision subsystem contains a block for adaptive formation of control strategies in real time based on Kohonen self-organizing maps). Practically implemented approaches to the object-oriented creation and implementation of technological regulations for combined electrotechnological systems for wastewater purification of continuous production. This made it possible to improve the energy efficiency of multicomponent effluent purification processes for a meat processing enterprise deviating the energy efficiency criterion from zero ± 9.6%, and small metallurgy ± 3.4%. The synthesis method of object-oriented technological regulations was further developed to improve the control algorithms for combined electrotechnological water purification systems of continuous production based on the energy efficiency criterion, based on assessing the efficiency of using energy resources as an integral parameter for the removal of pollutants from effluents. Intelligent energyefficient control of the process of removing the contaminants from wastewater is being realized through the synthesis of software and information control of the combined electrotechnology wastewater purification systems based on the object-oriented technical specifications for operation. Conclusion. An improved method for managing the operation of electrotechnological wastewater treatment systems for continuous production ensures compliance with the requirements for the efficient use of energy resources and environmental safety.
