Review of environmental factors: three proposed detention basins for Western Sydney Orbital within Liverpool local government area

The Western Sydney Orbital (WSO) is a major development a portions of which lies within the Cabramatta Creek catchment. To mitigate any adverse impacts on flooding patterns in the area three detention basins are proposed: a basin located between Ash Road and west of WSO at Prestons; a basin located on both sides of Illaroo Road and east of WSO at Hoxton Park and Prestons and a basin located between Cowpasture Road and Government Road east of the WSO at Hinchinbrook.

悉尼西部环线（Western Sydney Orbital, WSO）是一项重大基建工程，其部分路段位于卡布拉马塔溪流域范围内。为缓解该区域洪水格局遭受的不利影响，项目规划建设三座滞洪盆地（detention basin）：其一为坐落于普雷斯顿的阿什路与WSO西侧之间的滞洪盆地；其二为分布于霍克斯顿帕克与普雷斯顿境内伊拉鲁路两侧、且处于WSO东侧的滞洪盆地；其三为坐落于欣奇布鲁克的考帕斯丘路与政府路之间、WSO东侧区域的滞洪盆地。
