Evolution of Optimum Landfill Site for Disposal of Solid Waste Through Geoinformatics: A Case Study of Ahmedabad City

Solid waste management is one of the essential responsibilities of local government agencies, which is a primary goal to maintain the personal satisfaction of individuals and ensuring acceptable standards of well-being and sanitation. It is estimated that the Ahmedabad Municipal Corporation generates nearly 2200 tons of solid waste daily. Most of this solid waste will find its way to the Piranha landfill, which is to the southeast of the city of Ahmedabad. The city has seen the un-point of population growth over the last few years, and the inclusion of many new areas that are possible, there is an increasing demand that the current framework has to be sufficient to meet. The alternative landfill site thus uses geomatics methods based on physical, environmental, and socio-economic parameters and the multivariate index approach. Thematic maps, i.e., Land use/land dispersal, surface waters, groundwater potential, drainage, infrastructure, were prepared using Indian Remote Sensing satellite data. Census records and the Ahmedabad Municipal Corporation provided socio-economic data and other relevant environmental data. Multivariate index analysis was performed using the analytical hierarchy process, taking into account the seventeen parameters. These parameters were weighted using a pair-wise comparison technique to calculate the matrix of the weight-dependent Satty's matrix. The landfill site suitability index is processed using a weighted index strategy. All exclusion criteria were then masked, and the rest were classified into four compatibility classes. The appropriate site was identified as a consequence and proposed for development as a sanitary landfill. This paper demonstrates the value of following the right geomatic and analytical hierarchy method in order not only to identify ideal landfill sites for the removal of solid waste but also to decide the best routes to bring the waste from the city to the landfill site in Ahmedabad (India).
