Abstract

Network are an important part of the infrastructure of our society. The investment that is needed for construction and maintenance of this network is so huge and thus any saving in the cost of these networks may result in considerable reduction of total construction cost. The aim of the optimal design of sewerage network is to find a cost effective solution that minimizes capital investment while insuring a good system performance under specific design criteria. Two main cost of sewerage network design are excavation and pipe cost which often create contradictory objective in the design of sewerage networks. Any reduction in pipe size is likely to result in an increase in pipe slope and consequently excavation costs. Reducing excavation cost on the other hand requires milder slopes for pipes, leading to larger pipe size for carrying the design discharge therefore finding an economical design for sewerage networks require an optimal trade-off between pipes and excavation costs which can be easily achieved by engineering judgment. This paper pertains comparison between two methods i.e. simplified method (design 1) and conventional method (design 2).
