Mitigating Storm Drainage System Impacts from Litter and Debris

The objective of this research is to analyze current best practices for collecting/removing litter and debris from the highways; and provide recommendations on efficient, more productive and cost-effective ways to keep litter/debris from clogging the urban highway drainage system. Currently, Ohio Department of Transportation (ODOT) collects litter from the highways manually. The manual collection process is expensive, and labor intensive. Analysis of data provided by ODOT concluded that at current prices, the cost of collecting a litter bag is $31.38/bag. The research concluded that there are many challenges associated with roadside litter that prevents the use of a single general purpose litter removal machine. The roadside litter collection machines commercially available typically use vacuum action to lift the litter. The research evaluated several types of vacuum based machines and recommends that ODOT further evaluate the tractor-pulled Trilo S8. Although the S8 is not effective in all situations, it was found to be the machine that is more capable of dealing with the challenges associated with roadside litter. However, a conclusive evaluation of the cost effectiveness of the Trilo S8 will require additional research. The research also recommended that ODOT field tests various types of drain inlet screens to assess their performance at different locations in Ohio. Such screens have environmental and economic benefits. The preliminary cost benefit analysis has determined that the payback period of screen installation can be as low as 1.2 years.
