Priority-Based Model for Rehabilitation of Water Networks Using FAHP (original) (raw)

2022, Research Square (Research Square)

Prioritizing water distribution networks rehabilitation is a challenge for decision-makers due to the various and complicated elements that are involved in the decision process and mainly the high cost of such projects. Using a multicriteria approach for prioritization of water network rehabilitation will strengthen the decision-making process and provide a base for a cost-effective solution. Although network rehabilitation is crucial to water management in Jordan due to being under water scarcity, refugee waves and frequent failure in old networks, current practices in giving preferences are based on the personal experience of certain stakeholders. This study develops a priority-based model using fuzzy logic to facilitate decision-making. The weights of contributing factors were calculated using the Fuzzy Analytical Hierarchy Process (FAHP) after judging by stakeholders and water distribution projects' experts in the Jordanian water sector. Then, a priority model was built using a Microsoft Excel spreadsheet that produced a priority ranked list. The study results showed that the physical factors have the highest weight, followed by the operational, quality of service, socioeconomic, and environmental factors. Finally, the model was tested on five water networks in the Amman Governorate.
