The invention provides a runoff water purification system for removing pollutants which accumulate on road surfaces, thereby reducing the workload of the sewage water treatment plants and preventing environmental water pollution. The system 1 is installed under the ground of the side of the road 2 . Runoff water runs into the system 1 through a curb inlet 120 , is purified and discharged to a sewage pipe 56 . The system is made up of a concrete box 11 , in which a wall 10 separates the box into a maintenance tank 7 and a treatment tank 9 , both of which are connected to each other at their lowest ends. Runoff water flows into the maintenance tank 7 and to the treatment tank 9 , through the connecting conduit where pollutants are removed, and discharged to the sewage pipe.
