Exfiltration Trench for Post Construction Storm Water Management for Linear Transportation Projects: Volume 3 of 3, Athens Field Study

Based on performance, construction, and maintenance data from the Reno, Ohio, trench, a revised design using an open grate with aggregate and sand media placed in a fully enclosed prefabricated concrete chamber was installed on SR 550 in Athens, Ohio, and monitored for about two months. Forensics on the trench identified operational problems, and the trench was reconstructed. The new innovative design included a plastic bubble plate (patent pending) over the aggregate media. Monitoring of this new design over a nine month period showed improved performance over the current design and ease of maintenance. Average removal of suspended material that entered the trench was about 86%. Removal of metals generally corresponded to the influent concentration, ranging from 9% to 75%.
