Location Optimization of Wastewater Treatment Plants Using GIS: A Case Study in Umm Durman/Karary
Spatially-referenced and up-to-date information system is one of the most useful tools for effective wastewater planning, management and environmental protection. Therefore, it is necessary to have a system which provides facilities through geo-spatial relationships. The River Nile catchment is one of the most important watersheds in the Sudan in terms of providing for domestic, agricultural, and industrial purposes and for electricity generation. Thus, protection of this important water source is crucial in national development. But, only very few point source treatment plants are currently in operation and non-point source treatment plants are required to be established to protect the catchment from pollution. Locating wastewater treatment systems is one of the essential components, and that needs spatially-oriented data gathering, analyzing and visualizing. Further, GIS-BASED decision support systems for available treatment plants are well suited for informing improved analysis and understanding of the problems of available treatment plants to perform a reliability to improve analysis and understand of the existing situation to choose the appropriate location of treatment through a GIS MODEL BASE using ARCGIS. This study-plan solve the issues and undertaken logics of GIS to identify the critical socio-economic and environmental factors, and find a more comprehensive and convenient way to optimize the locations for wastewater treatment facilities that are suitable for different local conditions in Karary.
