Location Optimization of Wastewater Treatment Plants Using GIS: A Case Study in Umm Durman/Karary

Abstract

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.
