Modeling and Evaluation of Sanliurfa Province Hilvan District Wastewater Treatment Plant with Hardy-Cross Method and GIS Supported AHP Method

Obtaining sufficient amount of water with acceptable quality is the main objective of water distribution networks, but it also brings a fundamental challenge. Risk assessment of water distribution networks is quite important due to the scarcity of data on water quality, quantity and infrastructure conditions and various factors that may change its operation. Deterioration of water quality, quantity and infrastructure, together with inadequate conditions, may lead to general failure of the system. Therefore, a decision support system should be developed to determine vulnerable and sensitive areas within the network. In this study, hydraulic modeling based on demand algorithm, Hardy Cross Algorithms and Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) methods are proposed for the sustainable operation and management of water supply networks serving both drinking and irrigation water distribution systems in response to increasing population demands. In addition, in this study presented for wastewater treatment in Hilvan district of Şanlıurfa province, it is aimed to determine the water in the wastewater treatment distribution network in the most appropriate way according to the demand. Environmental factors include precipitation, land use, geology and geomorphology, and protected areas. Economic factors include slope, wastewater transfer systems and land values. The determined factors are divided into sub-criteria according to their suitability for wastewater treatment areas and the corresponding values ​​are assigned. It has been determined that the solution gives better results using algorithms.
