Low Impact Development seeks to maintain or restore a sites' natural hydrology, maintain natural resource protection while meeting the Clean Water Act environmental regulatory requirements.
Terre Kleen, a hydrodynamic separator that provides up to 176 gpm/sf of treatment flow rate, can be utilized as part of a treatment train site design to obtain a cost efficient pollutant removal result. The small footprint of the Terre Kleen minimizes conflict with the property's natural vegetation and, thus, is useful in helping maintain the natural site features. Terre Kleen is easy to maintain and the annual maintenance costs are less than 5% of the initial capital expense. This annual maintenance expense compares favorably with any stormwater BMP, including any "green" or LID BMP.
