Permeable Curb and Gutters for Storm Water Control

Storm water pollution is a pressing problem and a variety of Low Impact Development- Stormwater Control Measures (LID-SCMs) have been studied for reducing pollutant loadings to receiving waters. However, no measures have been widely adopted at levels necessary to fully mitigate storm water pollution in high density urban environments. The research goal of this project is to develop a proof of concept for how new linear LID-SCM permeable materials could be installed along curb and gutters to treat non-point source pollution for regular streets. The configuration will entail hollow core permeable curbs that collect filtered water to be conveyed as storm drainage. Pollutants are removed prior to entering receiving waters. Required permeability, porosity and associated material pollutant removal efficiencies and cleaning options need to be characterized for this storm water collection configuration to identify best form and function when utilized in urban environments. An experimental test apparatus will be constructed to simulate a typical street profile and water depths expected to occur during typical storm events. This apparatus will be used to determine: (1) the fraction of water that can be treated by the permeable curb, for a typical design rain event; (2) the amount of solids that may be removed from the water treated; (3) the potential for clogging and fouling of the permeable curb; (4) the ability to recover lost performance through vacuum cleaning of the porous curb; and (5) training of students, outreach to the public, and dissemination of research findings to the broader scientific community.
