Currently, large roadway debris (e.g., hubcaps, plastics, tire shreds) can enter storm sewer systems via the windows of barrier inlets. When the large debris clogs the outlet pipe, other sediment and debris builds up resulting in Ohio Department of Transportation (ODOT) needing to use vacuum sewer trucks to clean out these basins. If left unattended, clogged pipes can lead to ponding on the roadways creating dangerous conditions for motorists. The cleanout process is both labor and time consuming. It also requires extensive maintenance of traffic (MOT) setup and tear down and exposes highway workers to prolonged unsafe conditions along busy stretches of interstates. An alternative to slowing or even stopping the debris buildup could be barrier inlet screens.
This research will assist ODOT in determining the best method for providing safe, efficient and cost-effective ways to keep litter/debris from clogging the urban highway drainage system. The chosen method should at a minimum provide safer working conditions and reduced cost for the department. |
