Abstract


One of the significant difficulties in most of massive urban areas is lack of land for waste disposal. According to UN world population prospects, about 54% of the population resides in urban areas which are anticipated to rise to 66% by 2050. India is estimated to add 404 million urban dwellers by 2050. The substantial increase in the population growth has lead to the immense generation of waste. 5000 TPD of municipal solid waste is being generated from Greater Hyderabad Municipal Corporation (GHMC). In many places, the solid waste generated is dumped unscientifically onto the open lands. So there is a need for optimized potential site selection for disposal of waste. This paper mainly focuses on selection of potential site for the disposal of municipal solid waste generated from GHMC area using Geographic Information System (GIS) and Analytical Hierarchy Process (AHP). In AHP, weights were allocated to each criteria based on relative importance with respect to each other and ratings are assigned depending on its magnitude of impact. Various factors are considered in the siting process were categorized into environmental and economic criteria. Road networks and slope were clustered under economic basis and water bodies, sensitive sites, groundwater levels and land use were clustered under environmental basis. For all criterions, thematic maps were generated and then combined with AHP using GIS for site selection.
