Energy consumption in water supply systems (WSS) is closely connected with water demand. Especially in the case of oversized water supply systems for which consumers\u2019 water demand is at least 50% less than previously planned and flow velocity in some parts of the system is below 0.01 m\u00b7s\u22121, this problem of excessive energy consumption can be observed. In the literature, it is difficult to find descriptions and methods of energy management for such a case. The purpose of this study was both an evaluation of the current demand of an oversized WSS and a preliminary technical analysis of the possibility for energy saving. Solutions are presented that resulted in improvements in energy management, thus increasing energy efficiency. The conducted analyses indicate the wide use of numerical, hydraulic models, among others, for the needs of the sustainable oversize water supply systems management in order to improve energy efficiency. Those simulations only give energy consumption results as a first step in the process of decision-making for the modernization process, in which investment costs should be taken into account as a second step. Thus, this paper emphasizes the crucial role of hydraulic models as a good analytical tool used in decision support systems (DSS), especially for large, oversized water supply systems.<\/jats:p>","DOI":"10.3390\/en14165101","type":"journal-article","created":{"date-parts":[[2021,8,19]],"date-time":"2021-08-19T00:11:49Z","timestamp":1629331909000},"page":"5101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Sustainable Water Supply Systems Management for Energy Efficiency: A Case Study"],"prefix":"10.3390","volume":"14","author":[{"given":"Izabela","family":"Zimoch","sequence":"first","affiliation":[{"name":"Faculty of Energy and Environmental Engineering, Institute of Water and Wastewater Engineering, Silesian University of Technology, Konarskiego 18, 44-100 Gliwice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ewelina","family":"Bartkiewicz","sequence":"additional","affiliation":[{"name":"Faculty of Energy and Environmental Engineering, Institute of Water and Wastewater Engineering, Silesian University of Technology, Konarskiego 18, 44-100 Gliwice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Machnik-Slomka","sequence":"additional","affiliation":[{"name":"Faculty of Organization and Management, Institute of Management and Logistics, Silesian University of Technology, Roosevelt 26, 41-800 Zabrze, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1075-0174","authenticated-orcid":false,"given":"Iwona","family":"Klosok-Bazan","sequence":"additional","affiliation":[{"name":"Department of Thermal Engineering and Industrial Facilities, Faculty of Mechanical Engineering, Opole University of Technology, Mikolajczyka 5, 45-271 Opole, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8112-1618","authenticated-orcid":false,"given":"Adam","family":"Rak","sequence":"additional","affiliation":[{"name":"Faculty of Civil Engineering and Architecture, Opole University of Technology, Katowicka 48, 45-061 Opole, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6890-7707","authenticated-orcid":false,"given":"Stanislav","family":"Rusek","sequence":"additional","affiliation":[{"name":"Department of Electrical Power Engineering, Faculty of Electrical Engineering and Computer Science, VSB\u2014Technical University of Ostrava, 708 00 Ostrava, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bluszcz, A., and Manowska, A.
