Special Issue Information

Dear Colleagues,

Water distribution systems (WDSs), classified as part of a critical infrastructure, aim at providing safe and sufficient drinking water access. The shape and capacity of water supply networks directly influences the water delivery and hence the optimal design of WDSs should be applied both to the development of new systems and to the upgrading of existing ones. The evolving challenges in urban water management such as the variability of water demands, aging infrastructure and environmental factors make the design process complex and challenging.

Within the context described above, this Special Issue invites original research and case studies focused on the optimal design process of water distribution systems. Key areas include the integration of hydraulic and water quality aspects into the design frameworks, taking into account cost and energy efficiency as well as the resilience of water supply network operation. Both practical applications and novel theoretical approaches of WDS designing are welcome. 

We look forward to receiving your contributions.

The primary objective of water supply systems is to ensure a reliable delivery of water in appropriate quantity, quality, and pressure. Designing water supply networks involves determining their geometric layout and capacity by selecting suitable pipe routes and sizes. Since the network layout influences pipe diameters, routing and sizing should be conducted simultaneously. This paper presents an application of the fractal-based method for designing water distribution networks (WDNs) in which the pipe routes and diameters are mathematically justified. The proposed approach takes into account the total pipe length, the total angular change in pipeline routing, construction costs, and water delivery priorities. Additionally, the method was tested under both quasi-real conditions (in the virtual city of Micropolis) and in real-world complex settlement. The results of the sizing process were also compared with those obtained using the genetic algorithm approach. Verification of the proposed method in both quasi-real and real-world scenarios showed a smaller total pipe length (by 9.53% and 12.17%), a lower maximum water age (11 and 87 h), and a comparable energy demand. The SRS method enables simultaneous determination of pipe diameters and layout routing, while ensuring proper hydraulic performance of the network due to the application of evolution theory rules which results in quasi-optimal solutions for WDN designing.

In accordance with the provisions of Directive (EU) 2020/2184, the largest water supply companies in the European Union (EU) will be required to report real water losses starting from 2026. The recommended water loss performance indicators (PIs) are the infrastructure leakage index (ILI) rating method or “another appropriate method”. The article presents results of research aimed at examining the relationship between the ILI and other selected PIs for water losses in selected Polish water distribution systems (WDSs) located in southern Poland. The highest values of determination coefficients for the linear relationships between the ILI and PIs were obtained in the case of intermediate normalized PIs for real losses expressed both as a volume of water per km of mains per 1 m H2O of pressure (R2 = 0.951) and as a volume of water per service connection per 1 m H2O of pressure (R2 = 0.9365). A very strong linear correlation with the ILI was also obtained in the case of basic normalized PIs for real losses, expressed as the volume of water per service connection (R2 = 0.7336). The moderate linear correlation was detected in the case of the percentage PIs for water losses. Results show that the recommended indicators, which can be used when the ILI cannot be calculated, should be the intermediate or basic operational normalized indicators. Full article

Water scarcity, climate variability, and increasing water demands are placing growing pressure on water supply and distribution systems, particularly in water-scarce environments. Optimization-based approaches have become central to improving system design, planning, and operation. This study presents a structured review of optimization techniques applied to water distribution systems under conditions of scarcity, intermittency, or aridity, and introduces a context-aware classification framework incorporating system scale, population, and scarcity severity. PRISMA (“Preferred Reporting Items for Systematic Reviews and Meta-Analyses”) principles are adopted. Relevant studies are identified through Scopus and Google Scholar, screened using criteria focused on system type, optimization relevance, and explicit consideration of scarcity, intermittency, or aridity, and classified by optimization stage, methodological approach, geographical context, and main findings. The review is dominated by benchmark network studies under water scarcity, while real-world applications in arid regions, such as Sub-Saharan Africa and parts of the Middle East, remain underrepresented. Deterministic least-cost designs are inadequate under water scarcity, whereas multi-objective approaches deliver more reliable systems. The review shows a mismatch between the optimization focus of the benchmark studies, which is mainly in the design phase, and the real-world applications, which mainly focus on optimization of the operations of the existing systems.
