The proposed work aims at developing a new set of indices to carry out the energy audit of water systems. The new set consists of both supply and distribution indices and results from a global energy balance applied to a reference network. In this study, the energy audit of two case study networks is presented by the aid of the new proposed indices. Moreover, for each network, different scenarios are considered, differing in the management strategy proposed to increase the energy efficiency of the system. The comparison of the scenarios in terms of indices has allowed for evaluating the most efficient strategy to reduce the pressure exceeding within the network, among different solutions. According to the results, with reference to the case study distribution network, installing both pumps as turbines and pressure reducing valves represent the most efficient strategy, containing the excess pressure and also offering possibility for energy recovery. Moreover, with reference to the water supply system assumed as further case study network, the strategy exhibiting better values in terms of indices is represented by a direct pumping towards the downstream distribution network, instead of pumping towards an upper reservoir and using a valve or a turbine to dissipate the excess pressure. In this work, the proposed indices are demonstrated to be a useful tool for water managers to identify, among different solutions, the most effective intervention to increase the energy efficiency of water systems.

Water utilities with limited water resources have difficulties arising from high levels of water losses in water supply networks. However, reducing these losses can be possible by monitoring, checking and managing the network correctly. In this study, it is aimed to reduce high levels of water losses through the hydraulic model by digitizing the existing drinking water assets in the central district of Kocaeli, İzmit. In parallel with this purpose, 69 district metered area have been established firstly within 567.95 km of İzmit with a total network length of 1143 km. In each isolated area, 684 of 2116 suspected leakages have been repaired by using active leakage control methods. Secondly, the pressure management system has been applied by using pressure breaker valves to prevent undetected leakages. A reduction of approximately 192.48 l/s has been achieved in the minimum night flow after active leakage control methods and pressure management activities. Thirdly, the replacement of end-of-life water meters has contributed to reduce apparent losses in isolated area. In conclusion, the water loss which was 45.40% in 2014 could be reduced to 29.50 % in İzmit district in 2019. According to the active leakage control, pressure management and meter replacement methods applied in this study, reducing water loss to 25 % throughout Kocaeli is possible by using these methods in other districts.

Applying pressure management reduces lost water and excessive hydraulic pressures in water distribution networks (WDNs). There are currently four different types of pressure management in the literature, i.e. fixed outlet, time modulated, flow modulated, and remote node modulated. The primary device used in pressure management is the pressure reducing valve (PRV) that dynamically controls the outlet pressure by moving up and down its main valve element. In this study, we firstly introduce the dynamic PRV model with four different pressure management types to the source code of EPANET v3.1 software and assess the effect of different valve opening schemes on pressure graphs and leakage quantities. The results showed that dynamic PRV significantly reduces lost water amounts and excessive hydraulic pressures in the WDN when valve opening is continuously adjusted. Our smart PM extension implemented into EPANET v3.1 software is publicly available in Zenodo repositories (https://zenodo.org/record/6243078).
