Abstract
Water distribution management methods are extremely complicated and multifunctional, requiring the modification of conventional approaches. One of the current concerns with the increase of urban areas in Addis Ababa due to population growth, economic development, inadequate and inefficient infrastructure, high water leakage, conventional network analysis and management, and potential shortages of water due to climate change is efficient water management of the urban water system. To meet the rising demand for water, it is critical to develop modern water management systems that provide real-time monitoring and decision support in order to properly manage the water supply network. In order to solve such issues, this study provides a Web-GIS based water analysis and management system, which enables opportunities to obtain the correct facts at the right time to make the right judgments. This paper describes and implements web-based architecture using open-source tools. The research relied on both primary and secondary data sources. GPS location tracking and key informant interviews were used to acquire the primary data. Secondary data were acquired from existing water network CAD map files. This information was gathered from the AAWSA. Other secondary data obtained from different institute and examined in narrative form using the descriptive analysis approach. According to the findings of this study, there is an imbalance between supply and demand. Only 72% of the total area is covered by a water supply. To collect data on the water supply system, the authority has limited resources and skills. In general, there is a lack of a comprehensive utility infrastructure governing framework, standards, and organizational coordination, as well as difficulties in utilizing GIS data. This study modified and integrated an open-source Web-GIS solution using GeoServer as a GIS web server, PostgreSQL/PostGIS as a relational database for storage, and a GIS application for producing spatial database of a water distribution network. An attractive and interactive geographic user interface was created with the help of MapStore. The developed system includes all water utility layers such as distribution pipelines, valves, and so on in a web map, the capability of querying the layer's information, sharing and printing maps, and some spatial operations such as distance and area measurement, as well as a mechanism for system administrators to add or remove the utility layer at a specific location. In conclusion, Water Distribution Network Analysis using WebGIS-Based systems offers significant advantages, improving efficiency, decision-making, and stakeholder engagement in water distribution networks.
