Abstract

Water loss management software tools for decision support is stated to be a challenging feature of any decision-making process. Pressure management is not an exception either as to what it could deliver to countries facing water disruption together with the rapid increase in water demands. The objective of this paper is to present a procedure in utilizing modelling tool called EPANET at a district meter area (DMA) level together with an incorporated pressure-reducing valve (PRVs) to minimize Fiji's ongoing water disruption crisis. This hydraulic model provides a theoretical visualization to the authority's management stakeholders on the pressure effects through real-time case scenario illustration as the local authority is subjected to financial budget constraints. This is adamant as researchers had stated that leakages in water supply networks (WSNs) make up approximately around 70% of the total water losses. This approach subjected within this project would be applied to a district metered area (DMA) that has the greatest number of burst leaks with the Suva-Nausori WDS. One could state that the resulting baseline of this approach would produce some reassuring results, whereby the method will use as a supporting tool to other DMAs within Suva-Nausori WDS in determining a desirable solution for water disruption reduction. Hence, this will also be used to determine the operational and non-revenue water (NRW) savings within the water utility. Lastly, all water utilities facing these water disruptions and leakages should be able to calculate their losses, investigate the basis for the leakages, prioritize the leakages based on its importance risk level and strategy generate solution scenarios. Then, applying the best competent solution strategies within the limited scope of implementation that could be cost-effective for any water utility.
