Stormwater Infiltration Device
Five field tests were conducted to evaluate the effectiveness of the Storm and Groundwater Enhancement System (SAGES) device for removing contaminants from stormwater. The SAGES device is a three-stage filtering system that could be used as a best management practice (BMP) retrofit to existing catchbasins/stormwater inlets or installed as a BMP for new construction. Stormwater is filtered and then discharged as it flows through three separate filtering sacks consisting of gravel on top, sand in the middle, and granulated activated carbon on the bottom. The tests employed two SAGES devices that were set up side-by-side. Both devices were constructed according to the vendor's specifications; one used a standard catchbasin, the second used a modified catchbasin filled with peat and wood chips. The tests were conducted so that a comparison could be made between the effectiveness of the two catchbasin configurations to remove stormwater contaminants. Water runoff from an asphalt parking lot during simulated rain events was utilized for the filtration tests. Particular attention was focused on the effects of variances of elevation head and influent suspended solids (SS) concentration on each configuration. The tests were performed by Battelle, Columbus, OH, under EPA Contract No. 68-C7-0008. The results of the testing showed that the highest removal efficiencies were demonstrated with elevated influent SS concentrations. Washout from the modified catchbasin appeared to contribute to increased effluent SS concentrations that clogged the SAGES filter sacks.
