On the Water Environment System in Water Sensitive Area—Building of Sponge Airport Stormwater System in Beijing New Airport

Abstract

This paper intends to study the water environmental system within water sensitive area of Beijing New Airport, further to research how it realizes the objectives of effectively controlling urban drainage and flood, scientifically utilizing and managing stormwater resource and efficiently reducing the total runoff volume and pollution, then building the stormwater system of “sponge airport”. Through analyzing the problems in the water sensitive area and some limiting factors of airport building, this paper will emphasize the system of stormwater drainage and storage, the system of controlling runoff volume and pollution, the system of recycling stormwater and the system of digitalized stormwater management. The design philosophy and construction method of “sponge airport” as far as functional division of airport and mutual connection of various systems are concerned, and the construction goal of “sponge airport” is put forward. Based on these researches, this paper will state how the construction objectives of new airport are realized and how the different systems provide guarantee to its goal of being an advanced international aviation hinge.
