“…On the other hand and from an environmental point of view, leakage involve energy and material losses since they are necessary to transfer and treat the water in a distribution system that is subsequently lost (European Commission, 2013). In other words, reducing leakage is essential to the overall efficiency and financial sustainability of urban water because it provides additional revenues and reduces costs (Berardi et al, 2014).…”

“…Detailed guidelines on the compilation of a WDN model from existing geographical information systems (GIS) and end-user data are generally not available, especially within the southern African context. According to Berardi et al (2014), data availability is a major issue in many water utilities. Although some water utilities have network data in GIS format, the accuracy is not always acceptable, and some data is missing.…”

This paper presents the development of a methodological approach based on the integration of free-of-charge open-source software, e.g. QGIS and EPANET, and engineering practices applicable to water distribution network design. The use of QGIS and EPANET, as well as the integration thereof with sound engineering practices and judgement, proved to be both viable and practical to enable practitioners to create a water distribution network model of an existing network in smaller developments or towns. Typically, in the latter smaller developments or towns, the professional cost associated with the additional time required when commercial licensed software is used, could be lower than the actual cost associated with the procurement of the licensed software itself. Hence, the developed process flow diagrams will not only potentially save time and money in comparison to a traditional, manual approach in EPANET, but will also provide guidance to practitioners and assist smaller municipalities in southern Africa facing challenges in terms of outdated records and budget constraints. It is envisaged that the implementation of the overall methodology will contribute to improved water infrastructure planning, design and management, especially in the southern African context where water resources are scarce and service delivery remains a pressing issue.

“…The author proposes to divide the water supply network into 15 DMAs, which is a modern management solution [20]. Each district can be independently analyzed using flow meters and pressure transducers to improve system knowledge, to realize the water balance of the area, and to locate water losses.…”

“…A DMA is a set of nodes enclosed in specified and permanent boundaries defined in order to install the smallest number of metering devices. DMAs identification is commonly realized using an empirical approach based on technical experience [20] even if new methods, survey sound leakage in water supply pipelines MATEC Web of Conferences 193, 02001 (2018) https://doi.org/10.1051/matecconf/201819302001 ESCI 2018 periodically [21] orgraph theoretic and graph partitioning principles used in distributed computing have recently been proposed.…”

The research that was conducted on the water supply network of Phan Rang city, Ninh Thuan province, is aimed at using renewable energy to optimize the management and reduce the water loss. The research has conducted DMA (District Metering Area) setup, construction and installation of flow meter and pressure reducing valve chamber for flow and pressure control with active pressure regulation, and the use of hydraulic power generator to generate power at the site. Research results provide management agencies, in particular, water supply companies, with optimal solutions in network management and energy saving, reducing the amount of water loss effectively, thereby increasing revenue and saving clean water - precious resources are gradually depleted.
