Barrier Inlet Screens to Mitigate Debris in ODOT Storm Sewers

A wide range of debris from fine sediments to hubcaps and tires can enter ODOT roadside drainage inlets, disrupting the hydraulic capacity of sewer systems. This often leads to increased stormwater spread and ponding on roadways - a serious danger to motorists. Barrier inlets are particularly vulnerable to these issues given their minimal separation from the travel lane and the relatively small size of their openings. Therefore, the use of barrier inlet screens may alleviate these issues by reducing the amount of debris entering inlets. This research project is aimed to provide ODOT with the knowledge and evaluation criteria to determine which inlet screen products and/or practices are best suited to protect barrier inlets located along roadways.
