In November 2011, a grant from the New England Interstate Water Pollution Control Commission (NEIWPCC) funded a retrofitting project at the Parsippany-Troy Hills Police Department parking lot. Three Filterra® bioretention units were installed throughout the parking lot to improve the quality of stormwater flowing into the nearby Troy Brook. A type of tree box, Filterra®s are considered a green infrastructure best management practice (BMP) for stormwater treatment. Through filtration and biological assimilation, they remove solid waste, sediment, oils, and nutrients from runoff, resulting in cleaner discharge.
Parsippany’s Filterra® boxes are the first of their type to be installed in New Jersey. Since Filterra®s are an affordable and small-scale way to improve runoff and protect local waterways, they can be viable in a range of settings. The five videos below provide an introduction to the Filterra® system. Filmed and produced by the Rutgers Cooperative Extension of Morris County, the videos aim to provide enough information for municipalities and organizations to determine whether Filterra® boxes are appropriate for their stormwater treatment needs. Before municipalities invest significant time in contacting engineers and the Filterra® company, they can use these videos to understand the cost, logistics, and maintenance of the units.
