An optimization procedure for the layout and component size optimization of sewer network

Praveen Kumar Navin, Mayank Varshney, Y.P. Mathur, Harshil Bhatt.


The optimal design of a sewer system, two sub-problems required to solve the optimal layout generation of a base network and optimal design of sewer component sizing simultaneously. This paper goals to acuaint a technique to solve the issue of sewer network layout and component size optimization. An algorithm generation of a predefined number of spanning trees is used to extract all prescribed number of sewer layouts from a base sewer network.The LQ (sum of the product of individual link length and its discharges of a layout) function is used to find the optimal sewer layouts from the generated layouts while the PSO (particle swarm optimization) algorithm is used to obtain the optimal component sizes of the selected layout. The proposed strategy is applied to address the Sudarshanpura sewer network (situated in Jaipur, India) problem.It has been observed that the optimal sewer layout for total system optimization is one where the LQ has the minimal value.

Key words: Sewer networks;Layout optimization; PSO; Component Sizing
