Layout Optimization of Sewer Network Using Minimum Cumulative Flow in the Sewer Network

Abstract

The municipal bodies in Indian megacities are facing several problems to maintain a good management practice with the massive solid wastes generated at all corners of large cities. This unique study used inbuilt optimization techniques and self-modified algorithms of the network analyst tool in the platform of Geographical Information System (GIS) to propose the optimized paths for municipal solid waste (MSW) collections at Kanpur, India. The input parameters used in modeling exercise were geographical location of waste points, existing road network, pro- posed transport routes, and locations of the dumping yards. The zone with eighteen wards having thirty-three locations for collection and two transfer stations for disposal of MSW was used as a test bed for the simulation exercise. All the locations were modeled separately to find respective optimized collection routes for solid waste management. This study found the reductions in haul distance as 27.78 ± 10.2% for the selected network. Keywords
