“…Taking into account the results of model calculation, assessment indicators for individual processes are defined. In these methods, mathematical models of water transport systems [19,21,22,[30][31][32][33]36,37] are often used. The assessment is usually performed within enterprises, as part of the analysis of technical condition and management of infrastructural assets.…”

“…In an energy balance, the amount of energy flowing into the system (natural and shaft energy) is compared with the amount of energy supplied to users or dissipated through imperfections of the system. There are several energy balances presented in the literature [19,[30][31][32]37]. In all cases, it is emphasized that energy dissipation occurs in:…”

Energy assessment is one of the most important parts of water utility performance evaluation. In recent years, many methods for the evaluation of energy transformation in water distribution systems have been presented in the literature. The methods vary in terms of the scope and aim of assessment. The main objective of this paper was to give a review and comparative analysis of the methods for assessing the energy efficiency of water supply systems, which are described in the scientific literature and technical standards. Because the energy assessment of water supply systems is performed for different purposes, it is not possible to indicate one universal method. The main aim of the research was to present and analyze the methods currently in use. The review of different performance assessment methodologies provided information on issues related to the classification of methods, energy balancing, determination of reference values for performance assessment, the use of supporting computer tools, and the importance of data reliability. Gaps, challenges, and possibilities for future research were also described.

“…Water utilities are currently aware of the need for reducing energy consumption and corresponding costs and are looking for innovative ways to improve energy efficiency. The latter can be achieved by improving pumps' efficiency, optimizing pump scheduling and changing the pipe system layout [2] as well as by recovering part of the excessive energy [3,4].…”

Enhancing energy efficiency of water supply systems by recovering part of the excessive pressure is currently an issue of growing interest for water companies. The installation of micro hydro plants for energy recovery can be profitable in sites with excessive pressure, though requiring proper technical and economical evaluation. This paper presents a methodology for assessing the energy recovery potential in water supply systems under high seasonal demand variation. The methodology is based on the calculation of head and flow rate conditions that maximize energy production for a specific energy recovery technology, given available head and flow rate ranges. The methodology is applied to the inlet of a storage tank of a water transmission system using hourly collected data over one year. Results show that, in systems of high variability of flow rate, the installation of turbomachines in parallel is necessary for maximizing energy recovery and that the developed methodology returns lower, but more realistic, energy production estimates than other approaches based on average head and flow rate data.
