“…The Polokwane Central DMA was isolated from 7 operational clusters consisting of 14 regional water schemes that comprises of approximately 6000 km to form the CoP water asset portfolio. The Polokwane Central DMA was isolated for hydraulic modelling in prior research and does not currently reflect the operational configuration of the network [12].…”

“…Due to a lack of historical flow data within the Polokwane Central DMA, the end user average annual daily demand (AADD) was estimated by classifying the users per land-use, size, and level of service contained in the customer profile of the Polokwane Local Municipality Water and Sanitation Asset Management Plan. The study by Bonthuys et al [12] aligned the asset management classification of the Polokwane Central DMA end users to the classification of water demand for developed areas in South Africa as defined by the Guidelines for Human Settlement Planning and Design in South African municipalities [37]. A standard demand pattern was then applied to the AADD for either residential or industrial end users ( Figure 5).…”

“…However, the introduction of hydropower in a WDS is not only a solution for recovering energy. Similar to the hydraulic grade line principle of a PRV, a hydro-turbine also causes a pressure drop across the component and allows for downstream pressure control [12]. A series of hydro-turbines within a water distribution network result in a reduction in the average operating pressure of the system, with a consequent reduction of the average leakage from the network [13].…”

“…Initial study by Bonthuys et al [12]-only the energy recovery considered in the optimization of the location of turbines, and no consideration was given to the effect of energy recovery on leakage within the system. • PERRL procedure analysis by Bonthuys et al [19]-utilizes GA to optimize multiple objective functions and identify ERT locations based on several technical and non-technical (monetary) criteria.…”

Excess pressure within water distribution systems not only increases the risk for water losses through leakages but provides the potential for harnessing excess energy through the installation of energy recovery devices, such as turbines or pump-as-turbines. The effect of pressure management on leakage reduction in a system has been well documented, and the potential for pressure management through energy recovery devices has seen a growth in popularity over the past decade. Over the past 2 years, the effect of energy recovery on leakage reduction has started to enter the conversation. With the theoretical potential known, researchers have started to focus on the location of energy recovery devices within water supply and distribution systems and the optimization thereof in terms of specific installation objectives. Due to the instrumental role that both the operating pressure and flow rate plays on both leakage and potential energy, daily variation and fluctuations of these parameters have great influence on the potential energy recovery and subsequent leakage reduction within a water distribution system. This paper presents an enhanced optimization procedure, which incorporates user-defined weighted importance of specific objectives and extended-period simulations into a genetic algorithm, to identify the optimum size and location of potential installations for energy recovery and leakage reduction. The proposed procedure proved to be effective in identifying more cost-effective and realistic solutions when compared to the procedure proposed in the literature.

River infrastructures can be defined as facilities and structures that support all activities related to river. Many infrastructures that exist along river stream but few of them are listed and recognized as an important part in the river system. The condition of assets that support the river function should be considered since it determines the sustainability of water supply system for many areas. Starting from upstream, there were dam and reservoir that constructed to reserve the water. Moreover, the water can be distributed to the downstream area for many requirements, such as irrigation system, hydro power, industrial process, etc. In the other hand, dam and reservoir also functioned as flood control that protect the downstream area from flood and inundation. In alluvial river, there were erosions that occurs as river flow velocity could transported soft soil numerously. Hence, the river bank protections were built in order to protect the nearby river infrastructures. Therefore, the infrastructures recognition as preliminary assessment to the river asset management need to be done in order to maintain the river system.
