Abstract: The Stormwater Regulation and Storage Project in the western suburbs has a storage capacity of 6.8 million cubic meters, and its main function is to store 27 square kilometers around the Eight Major areas of The Xishan Mountains of the once-in-a-century flood not to be discharged into Beijing, ensuring the city's flood control safety. The infiltration control design combining bentonite waterproof blanket and infiltration pool were adopted in the project with the purpose of ensuring that the storage flood is fully infiltrated within the design time and meeting the requirement of "reducing the initial rainwater pollution to the groundwater". The project have been open to the public in 2019, and ecological water use has become very important. Therefore, it is necessary to make effective use of the rain-flood resources that entering the sand pit of Fushi Road to achieve the purpose of flood control, ensuring environmental water and saving water. Based on a large number of measured data, the current situation of water resource utilization in The West Storage Project was analyzed in this paper, and the targets and methods of further improving the utilization of water resources were put forward. Promoting the improvement of social and economic benefits.
