“…Relative to urban supply systems, the energy consumption in water supply networks represents 7% of the world's consumption of energy [80]. Water distribution involves an energy footprint between 0.18 and 0.32 kWh/m 3 , according to the California Energy Commission [81].…”

Analyses of possible synergies between energy recovery and water management are essential for achieving sustainable improvements in the performance of irrigation water networks. Improving the energy efficiency of water systems by hydraulic energy recovery is becoming an inevitable trend for energy conservation, emissions reduction, and the increase of profit margins as well as for environmental requirements. This paper presents the state of the art of hydraulic energy generation in drinking and irrigation water networks through an extensive review and by analyzing the types of machinery installed, economic and environmental implications of large and small hydropower systems, and how hydropower can be applied in water distribution networks (drinking and irrigation) where energy recovery is not the main objective. Several proposed solutions of energy recovery by using hydraulic machines increase the added value of irrigation water networks, which is an open field that needs to be explored in the near future.Keywords: irrigation water networks; water-energy nexus; renewable energy; sustainability and efficiency; hydropower solutions; water management Hydropower GenerationSociety's energy consumption worldwide has increased by up to 600% over the last century. This increase has been a direct result of population growth since the industrial revolution, in which energy has been provided mainly by fossil fuels. Nevertheless, today and in the near future, renewable energies are expected to be more widely implemented to help maintain sustainable growth and quality of life and, by 2040, to reduce energy consumption down to the 2010 levels [1].Sustainability must be achieved by using strategies that do not increase the overall carbon footprint, considering all levels of production (macro-and microscale) of the different supplies. These strategies' development has to be univocally linked to new technologies [2]. Special attention must be paid to those new strategies that are related to energy recovery. These new techniques have raised interesting environmental and economic advantages. Therefore, a deep knowledge of the water-energy nexus is crucial for quantifying the potential for energy recovery in any water system [3], and defining performance indicators to evaluate the potential level of energy savings is a key issue for sustainability, environmental, or even management solutions [4].Energy recovery, with the aim of harnessing the power dissipated by valves (in pressurized flow) or hydraulic jumps (in open channels), is becoming of paramount importance in water distribution

Abstract. Demak Waterwork Company (DWC) has served 21,178 customers with the capacity flow of 159.33 l/s. The capacity was predicted to reach 300 l/s or double in in 2027. The Water Distribution Networks (WDN) was developed in a large zonation, but the water supply to the customer was not well managed. Low pressure especially at peak hours, the level of leakage, and the difficulty to detect leakage are water supply problems should be solved by WDN. The objectives of this study are forecasting the demand for drinking water in the 2036 and designing a zoning system to meet future needs of drinking water. This study applied Epanet Modelling to simulate the water network system in existing and predicted condition. The result show that the characteristics of pipes, pipe materials and pipe size based on the load of drinking water should be considered for pipe replacement. Some developmental strategies e.g. improving the capacity, establishing zones, and resizing the pump capacity improve the reliability and efficiency of the water distribution network. The pressure model resulted in sufficient value to supply the whole area of more than 0.5 bar in service pipe.

“…For this purpose, water companies use variety of water treatment and transport processes, which are highly electricity consuming. It is estimated that means of water distribution absorb from 3% to 7% [1,2] of electricity, worldwide. According to Copeland and Carter [3] energy consumption in WSS is distributed as follows: 67% for tap water pumping, 14% for water treatment, 11% for raw water pumping and 8% for in-plant water pumping (e.g.…”

“…Therefore any efficiency improvements in involved processes would be highly desirable. There are several methods that have proven to have positive impact on reduction of energy consumption in WSS [2][3][4]. They can be divided into three groups: (a) implementation of control and monitoring systems SCADA (Supervisory Control And Data Acquisition), (b) installing higher efficiency pumps motors, and drives, (c) generating energy in WSS using alternative energy sources.…”

Abstract. The decreasing amount of fossil fuels and deteriorating air quality forces the governments to introduce a rational energy management in all sectors of economy. At the beginning of the twenty-first century many water supply systems (WSSs) were oversized because of the reduction of water consumption, especially in industry. This resulted in high energy consumption in the pumping stations. Improving pumps operation will decrease energy consumption and also the water prices. The purpose of this paper is to present a method of energy optimization in WSSs. This paper presents an analysis of energy consumption in a selected water supply system. In this study pumps located in water treatment plants and pumping station cooperating with the tanks are analyzed. The study used hydraulic model of the WSS created in MOSKAN-W, which defines pumps' parameters such as flow, head, and efficiency. Using optimization options of calculation software several scenarios of energy costs were prepared.
