Solid waste dumping site is a Couse of dangers problem in Koladiba town as all solid wastes are not dumped in suitable sites. The main target of this research study was to select suitable solid waste disposal sites in Koladiba town by applying Geographic Information System and MCDM technologies. For the suitability analysis of the land in Koladiba Town for the purpose of solid waste disposal sitting different data are employing as input data for Arc MAP. DEM is used to generate slope, drainage using the computer program Arc MAP 10.3.1(ESRI). GIS and RS are applies to indicate unsuitable areas based on the set criteria. Each criterion are distinguish into four suitability classes, namely, highly suitable, moderately suitable, less suitable and unsuit able (restricted) For this study, weighted overlay analysis is used for each input layer . These are the distance to river, built up, road, slope, water pipe line, reservoirs, boreholes and land-use/land-cover. Selections were examine for setting a suitable site by taking into consideration multiple criteria and contradictory objectives in a GIS -based MCE technique, using WLC analysis. The final suitability map was prepared by overlay analyses on Arc map and leveled as high, moderate, less suitable, and unsuitable regions of the study area were determined. The results shows that 66.95% of the study area is unsuitable for solid waste dumping; 13.32% less suitable; 3.08% moderately suitable and 16.65% highly suitable. The Highly suitable area was bare/grass lands and 0-10% slop that not use for other purposes. The direction of the site are eastern and north western part of the town that are least environmental and health risks.
