Rapid Urban growth and development is one of the major causes for the solid waste disposal which is assuming alarming proportions now a days. The Municipal solid waste produced by our cities pose serious health problem in India as well as in the World. Most of the Indian cities do not have proper arrangements for urban solid waste disposal. The main problem for the in waste disposal management is to find out suitable sites for the urban solid waste disposal. Gwalior, certainly is one of the leading commercially developed urban city of northern Madhya Pradesh. The city has been expanded rapidly in the last few decades. In the present study the urban solid waste disposal site selection for Gwalior city has been done using geospatial technology. The multi criteria analysis has been considered for the present site selection of solid waste disposals. The seven different criteria that are taken into consideration have been grouped in to two categories as physical (lithology, geomorphology, land use and land cover, slope) and socio-economical (population, distance to roads, distance to drainage) and analysed for the site selection in a GIS environment by multi criteria weighted overlay analysis method. Finally on the basis of degree of suitability a site suitability map has been prepared showing very low, low, moderate, high and very high suitable areas for the disposal of solid waste. The result shows that 6.20% and 10.22% of the area are very highly and highly suitable for disposing of Municipal solid waste. These areas are mostly confined to the north and south to south eastern part of the area. The paper highlights the capability of geospatial technology in the urban waste disposal site suitability analysis.
