The paper presents a brief description of the problems of making technological decisions to manage the development and functioning of water supply networks in conditions of territorial, structural, and temporal disconnection of the decision-making processes at WKX enterprises. An approach to overcome such problems is proposed, based on the application of end-to-end modeling technologies and a single information space of the enterprise based on the application of the ANGARA-VS information and computing complex. Its brief characteristics and functions are given. The experience of automation of development of operational modes and dispatching management and development of perspective schemes of water supply in Municipal Unitary Enterprise "Vodokanal", Irkutsk.

Within the frame of upgrading and modernisation of the Water Supply System (WSS), our work is focussing on the safety systems/devices implemented or that should be implemented in the WSS. The implementation of safety systems is supposed to reduce hazard occurrence and hazardous consequences in case of a WSS unsafe disruption. To assess this reduction, we preconise the use of the safety integrity levels standards. The implementation of the safety systems/devices is undertaken on the ground of the multi-barriers safeguard approach. The “Water Contamination Hazard” is considered in the paper. A case study is presented, assessed and conclusions are drawn. The methodology presented in the paper and the results of the case study assessment will contribute to the decision-making regarding the upgrading of the safety and the performance of the WSS.

Abstract This paper provides a review of the changing nature of the water–energy nexus in urban water supply systems (UWSSs) due to the primary long-term drivers of climate change, population growth and technological development from the ‘energy for water’ perspective. We identify both the physical changes in UWSSs, as well as the changes in the attributes of the system, both of which contribute to the changing nature of the water–energy nexus. We provide an overview of responses to this change in the water–energy nexus through the lens of four application areas, namely long-term planning, system design, system operation and system rehabilitation, based on the review of 52 papers. Ten responses in three categories are found to be commonly considered in each of the four application areas. The three categories are energy or greenhouse gas reduction, integrated modelling and planning, and improving social benefits. The main drivers of these responses may vary with the application area. Based on the review outcomes, we outline the gaps in the responses in relation to the changing nature of the water–energy nexus in UWSSs, providing directions for future research on improving UWSS efficiency considering the long-term drivers.
