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.
Claims20
1) A filtration system comprising:
- a roadway having a scupper extending through the roadway between a top surface of the roadway and a bottom side of the roadway;
- and
- a filtration media disposed within the scupper.
8) A filtration system comprising:
- a roadway having a scupper extending through the roadway between a top surface of the roadway and a bottom side of the roadway, wherein the scupper is defined by an outer tube installed within the roadway;
- an inner tube disposed within the outer tube and removably secured to the outer tube;
- and
- a filtration media disposed within the inner tube.
15) A method of filtering liquid runoff from a roadway, said method comprising the steps of:
- forming a scupper in a roadway, wherein the scupper extends through the roadway between a top surface of the roadway and a bottom side of the roadway;
- installing a filtration media within the scupper;
- and
- filtering liquid runoff from the roadway by allowing the runoff to gravity flow through the filtration media.
