Optimization of Storm Water Drainage Network using Ant Colony System

The major objectives of storm water management include protecting the environment; minimize the event of flooding and supporting healthy streams which result in healthier and more sustainable communities. Effective storm water management gives ecological, social, and financial advantages to the community. The present study focuses on optimization of storm water collection system by application of proper routing algorithm. The main aim of the present study is to minimize the total cost associated with construction of storm water drains without compromising its discharge carrying capability. In this study a meta-heuristic approach based on Ant Colony System is used to optimize the multi-objective problem of storm-water drainage system. An illustrative example inspired from real life storm-water management problem has also been solved. The problem has been solved by varying the weightages of the heuristic values for drainage length and slope. The findings indicate that present approach provides a scientifically credible solution for storm-water drainage network optimization in urban areas.
