SW Exfiltration

Ex filtration systems are usually placed on the major road edges for quick drainage of stormwater from the road into this pipe system located under the road and a gradual release of this water back into the aquifer. These systems are located in high traffic areas of major roads that have had severe flooding in the summer rains.渗滤系统（Ex filtration systems）通常设置于主干道边缘，用于快速将路面雨水导入铺设于道路下方的管道系统，并将收集的雨水逐步回补至含水层。此类系统多部署于曾在夏季降雨中遭遇严重内涝的主干道高流量路段。
