Terre Hill Stormwater Systems Enhances Low Impact Development

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.

Terre Kleen Pretreatment Works

Terre Kleen removes pollutants from stormwater runoff. Terre Kleen primary chamber permanently removes gross pollutants such as oil, grease, trash, debris and sediment before these pollutants can enter and cause malfunction of an underground infiltration basin such as a Terre Arch system.

Picture shows the primary chamber of a Terre Kleen installed 12 months prior in a shopping center parking lot. If you do not design for pretreatment your BMPs will lose functionality and they will fail because they are clogged and choked up with stormwater runoff pollutants.

Don't risk a malfunction of your underground infiltration basin. Don't subject your LID BMP to gross pollutant and sediment overload.

Preserve the useful life and functionality of your stormwater LID BMPs.

Terre Hill Stormwater Systems = Green Infrastructure and Smart Growth

Green Infrastructure is defined as: technologies that infiltrate, evapotranspire, capture and reuse stormwater to maintain or restore natural hydrology.
Terre Kleen is a stacked inclined plate hydrodynamic separator that pretreats stormwater by removing oil, grease, trash, debris, sediment, and nutrients and heavy metals that are attached to the sediment. The Terre Kleen does all of this in a very compact structure footprint. A key benefit of using a Terre Kleen in a LID BMP overall design is that the pretreatment of the stormwater runoff will remove the pollutants carried by the runoff before the stormwater enters the LID BMP. Oil, grease, trash, debris and sediment will not enter the LID BMP.
Terre Arch is a multi-arched precast concrete structure that is designed to maximize stormwater infiltration while facilitating use of the surface area above the Terre Arch. Terre Arch promotes Smart Growth by minimizing the land area required for development.
