“…The operating conditions of the megapolis WSS are formed under the influence of many factors that depend on the reserves and quality of natural waters, the technical parameters of the WSS, and the way of life of people. The WSS should provide the population of the megapolis with drinking water that meets quality standards, under-regulated pressure, and in the required quantities [5,60,61]. The optimal balance between consumer demand and water supply, which excludes water shortage and ensures a reliable water supply for social and production purposes, is the main guarantee for the vital activity and functioning of the CMFMCs of the metropolis.…”

“…The features of the water supply process, in particular, the use of water as a product and as a natural resource, not only determine the efficiency of electricity use in individual structural elements but also affect the efficiency of energy resource use in the WSS as a whole. The pumping stations subsystem, which ensures water pumping, is the largest consumer of electrical energy among the subsystems involved in the water supply process [5,60,[63][64][65][66][67][68]. The electricity consumption for pumping water depends on the volume of pumped water and the generated head (pressure).…”

This study is devoted to improving the energy efficiency of urban infrastructure systems (UISs), in particular, the centralized water supply of a city multifloor manufacturing cluster (CMFMC), by developing the principles of effective energy consumption management. The CMFMCs are located in the residential area of a megapolis and include manufacturing and service enterprises, residential and non-residential buildings, and a city logistics node. Demand monitoring and identification of the influence of seasonal and social environmental factors on its fluctuations is considered as a tool for identifying changes in the operating conditions of the water supply system (WSS) for the CMFMC facilities. To identify the typical operating conditions of water supply facilities, an approach is proposed that involves the analysis of daily water consumption profiles (WCPs). The formation of a database, the formation of groups of the same type of daily WCPs, and the construction of typical daily WCPs for typical groups and their description are the main stages of the proposed approach. The database contains a set of classification characteristics that describe the daily water consumption and its unevenness, as well as the shape of the daily WCP. The principal component analysis was applied to determine the dominant components of daily water consumption. A set of morphometric parameters was used to describe the shape of the daily WCPs. The methods of cluster and discriminant analysis were used to identify the influence of seasonality and social factors on water consumption and to form groups of the same type of daily WCPs. The analysis of sets of similar type of daily WCPs for typical days of typical seasons was carried out for a formalized description of the typical operating conditions of water supply facilities. The results of the analysis are the clarification of the equations of the dominant components of daily water consumption, the determination of the average values of the characteristics of daily water consumption, and the construction and description of typical daily WCPs for typical operating conditions of water supply facilities. The research results were obtained on the basis of the data of the monitoring systems for water supply enterprises in Ukraine and Poland in 2021–2022. The obtained results are the basis for planning the water supply process and adjusting the operation modes of WSS pumping stations for the CMFMC, as well as planning power consumption for typical operating conditions, which will contribute to increasing the efficiency of water and electricity use.

The article contains part of the results of the project Protection of Natural Water Resources in Polanica-Zdrój through Intelligent Water and sewage management. The article presents the research results into the water supply network (WDN). The aim of the research was to improve the quality of water and reduce the cost of its treatment by reducing the age of the water. For this purpose, a model was built that takes into account the time in which water stays in a given section from the moment it flows out of the intake and mixes with the water already present in the network. The research was preceded by the construction of a model based on GIS geodetic data and a digital terrain model. On the basis of the simulations and analyses carried out, a solution was proposed to reduce the average age of water in the investigated WDN.

“…One of the goals of this organization is to achieve better water management; for example, water companies are required to reduce their water losses and this is forced by financial means [5]. On the other hand, water scarcity can increase the difficulty of supplying water of sufficient quality to end users [6]. One of the tools used in water management is a mathematical hydraulic model [7].…”

The age of water in the municipal water supply system is one of the main factors influencing water quality. To create a good quality hydraulic model, one must achieve a high level of calibration accuracy with real life measurement data. Before we start building our model, we must decide on the model’s level of detail, that is, its complexity. We must know if skeletonization of the network graph and different hydraulic timesteps have an influence on simulation results. This study strives to prove that this decision can lead to unforeseen problems during the calibration process, thus making it impossible to achieve the required calibration precision. In order to prove this, two different model variants were created with different levels of graph detail, and simulation data results were used to determine which model variant is best suited to achieve the highest fidelity simulation results. Following this, the chosen model was run with different hydraulic timestep settings, which made it possible to showcase the large influence this setting has on achieved results.
