In recent years, the climatic changes an too radical. So rain rate cannot be forecasted with full certainly. Traditionally, the design of Storm sewer system maybe time-consuming and less than lost-effective. But now we can use computer and optimal algorithms to facilitate the design of Storm sewer system. This study uses genetic algorithms to help constructer plan and design the Storm sewer system. The chromosome design represents a kind of system layout. We use genetic algorithm to find optimal layout and then perform Hydraulic. This study uses two cases to validate the proposed model. The first case includes a sewer system with 7 manholes. The proposed model can always find the true optimal design by comparing with Exhaustive enumeration. The second case includes 40 manholes. Where the rain rate is assumed stochastic. This model can find the optimal under specific condition levels.
