Abstract
A system and method for treating liquid runoff from bridge decks or other types of roadways are provided. The system includes vertical scuppers positioned at low points along a length of a bridge deck. Each scupper has a removable tube fitted inside the scupper with a filtration media for treating liquid runoff such as stormwater. During rainfall events, liquid runoff gravity flows downward through the tubes and the filtration media inside the tubes so that the liquid is treated before being discharged to the environment. The tubes can be removed to periodically replace the filtration media.
