“…It is mandatory to control the pressure or, if needed, the flow rate to reduce the hydrostatic pressure in the pipeline within the required limits. The control valves can be replaced by the SHPP to represent their function (Figure 4) [40].…”

The article is focused on the issue of blackouts in a water industry and the selection of a renewable energy source for a water treatment plant. In the case of power outage, it is necessary to constantly ensure the supply of a drinking water, if this requirement would not be met, it could cause of deterioration of hygiene and health of the population. To be able to convey drinking water during a blackout, it is mandatory to have a backup power supply. The state of the current water treatment plants in the Czech Republic is that they are using diesel generators as backup power supply, which causes air pollution. There are other options of power supply that can be used, such as renewable energy sources. By using a multi-criteria analysis method, renewable energy sources were analyzed for a water treatment plant in the selected region. Based on the results, it seems that the most suitable choice is a small hydro power plant at the entry points of water treatment plant. Other possibilities of renewable energy sources that may be suitable for a water treatment plant and the usage of a multi-criteria analysis method for a water treatment plant in other countries are also discussed.

“…Numerous studies have been conducted on the potential of energy recovery in water supply and distribution systems, with several successful installations globally [1][2][3][4]. Small-scale hydropower technology, applied in Water Supply Infrastructure, has been demonstrated to be a viable renewable energy to develop in South Africa [5,6].…”

“…Analysis of the previous research [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] catalysed the 2020 research study by Bonthuys et al [17], which developed a procedure employing a genetic algorithm (GA) to identify and optimize the location and sizes of hydro-turbine installations or conduit hydropower installations for energy recovery. The procedure, named PERRL [17], differed from the Creaco and Haidar [16] methodology by specifically focusing on energy recovery rather than pressure management.…”

Optimizing the Potential Impact of Energy Recovery and Pipe Replacement on Leakage Reduction in a Medium Sized District Metered Area

2021

The drive for sustainable societies with more resilient infrastructure networks has catalyzed interest in leakage reduction as a subsequent benefit to energy recovery in water distribution systems. Several researchers have conducted studies and piloted successful energy recovery installations in water distribution systems globally. Challenges remain in the determination of the number, location, and optimal control setting of energy recovery devices. The PERRL 2.0 procedure was developed, employing a genetic algorithm through extended period simulations, to identify and optimize the location and size of hydro-turbine installations for energy recovery. This procedure was applied to the water supply system of the town of Stellenbosch, South Africa. Several suitable locations for pressure reduction, with energy recovery installations between 600 and 800 kWh/day were identified, with the potential to also reduce leakage in the system by 2 to 4%. Coupling the energy recovery installations with a pipe replacement model showed a further reduction in leakage up to a total of above 6% when replacing 10% of the aged pipes within the network. Several solutions were identified on the main supply line and the addition of a basic water balance, to the analysis, was found valuable in preliminarily evaluation and identification of the more sustainable solutions.

“…In both cases, a pressure drop across the component allows downstream pressure control (Ramos, et al, 2010). The potential of energy recovery by means of conduit hydropower plants in water supply and distribution systems have been investigated by numerous researchers (Table 1) and there are already successful installations in many countries such as Switzerland, the Czech Republic, Spain, Hong Kong, Ireland, South Africa and the USA (Perez-Sanchez, et al, 2017;Güttinger, 2012;Gono, et al, 2012;Van Dijk, et al, 2015) . Table 2 shows examples of installed energy recovery installations in water supply and distribution systems, including turbine used, capacity and annual energy recovery potential.…”
