The weighted overlay analysis is done by using thematic layers like land use land cover, geomorphology, geology, soil, lineaments, ground water depth, distance from water bodies, distance from railway track, drainage density, road density ,distance from roads are used as inventory maps to arrive the suitable area to carry out decentralized solid waste management. The results revealed the suitable area in sqkm under five classifications as highly suitable, high to moderately suitable, moderately suitable, poorly suitable and not suitable.
