雨水调蓄池是一种雨水收集设施，主要是把雨水径流的高峰流量暂留池内，待最大流量下降后再从调蓄池中将雨水慢慢地排出。达到既能规避雨水洪峰，提高雨水利用率，又能控制初期雨水对受纳水体的污染，还能对排水区域间的排水调度起到积极作用。
流量演进在雨水调蓄池的设计计算和运行模拟中具有重要作用。
Flow routing plays an important role in the design calculation and operational simulation of storm detention tank.
最后，针对雨水的可调节利用，建立区域性雨水利用系统，分析研究雨水调蓄池在局部区域的应用。
Finally, for the regulative utility of rainwater, a rainwater regional utilization system is built to analyse and research the application of rainwater storage tanks in the local area.
在合流制排水系统中，排水泵站中设置调蓄池是解决城市初期雨水对水体污染的有效措施。
In order to solve the problem of pollution in confluence drainage system, which is caused by initial rainwater, setting storage pond under the drainage pumping station is a effective measure.
