The world population is growing at a rapid rate, and this has led to increasing product consumption, which has in turn created a considerable increase in solid waste from families, businesses, and agriculture, among other sources. The process of choosing a solid waste disposal site is challenging and time-consuming, requiring careful evaluation of a wide range of social, economic, and environmental variables. The investigation in this paper showed that ArcGIS may be used to find appropriate, scientifically-based options for dumping sites locates and determine the areas to be used for any particular activity, such as the construction of a base or a rubbish disposal area, using the Weighted Linear Combination (WLC) algorithm. The Geospatial Data Abstraction Library (GDal) library is used to help Python language scripts in QGIS 3.24.0 create the data set. As a result, the output image shows a range of values indicating the locations that are most and least acceptable according to the criterion. There are five locations in the vicinity of the villages that have been discovered to be appropriate for disposing of solid waste: Bajargaon, Ladai, Nawarmari, Salaimendha, and Nandera. The location closest to Nawarmari village, which has an area of 113.92 hectares, is determined to be the most ideal for the disposal of solid waste following network analysis route optimization.
