Abstract:

Rainwater plays an important role in the improvement of the drainage performance while leaving the drainage network structure and capacity unchanged. Based on the comparison of rainwater storage performance in projected rainwater drainage systems, it shows that the rainwater storage facilities based on the current rainfall intensity computing formulation can improve the drainage system. The results show that the decentralized rainwater drainage network in municipal drainage helps to reduce the designed rainfall intensity capacity in the drainage network. Thus, the effect can be equal to increasing the rainfall duration in the rainwater drainage network design. Therefore, the rainwater storage facilities in decentralized networks optimize the rainwater drainage network in community rainwater drainage design. It also reduces the capacity of the drainage network and improves the safety of the municipal rainwater drainage system in residential areas.
