In this study eleven factors, including village location, surface water, ground water, soil drainage, elevation, road network, ground water wells, slope, land use pattern, land capability and conservation area were applied, to select a suitable area for Banpru Municipality waste disposal site. Data were analysed using Weight method and Overlay technique of Geographic Information System. The study shows that the most suitable area, totalling 1,200 rais, is located at Ban Klong Pom, Moo 9, Tambol Banpru, Amphoe Hat Yai (roadside of Banpru - Ban Na Thongsuk ARD. road) 3 kilometres from existing waste disposal area.

The most suitable route for waste collect and transport from sources to waste disposal site was analysed using Optimum Routing techique, in Arcview Network Analyst program. This program divided Banpru Municipality area in to 5 zones routing distance of which are; 32.39, 34.49, 25.19, 33.14 and 21.09 kilometres respectively. In the second, the third and the fourth zone, the number of waste collection bins is sufficient compared to the volume of daily waste, as for the first zone and the fifth zone is not. Additional bins are needed for supporting 15,504 litres volume of waste in first zone, and 4,885 litres in the fifth zone.
