Terre Hill Concrete Products, working with the departments of Environmental Protection and Transportation, local governments and private industry developed a new solution for separating sediment from stormwater or runoff with fine particulates.

Terre Kleen is a separation and sedimentation device designed to receive storm water from the upstream collection system that efficiently separates litter and pollutants and settles sediment before the stormwater discharges into the stream or detention/retention ponds.

Terre Kleen meets the current U.S. EPA National Pollutant Discharge Elimination System Phase II, Storm Water Regulations for a Best Management Practice.

The Terre Kleen design uses aluminum inclined plates that function as inclined sedimentation basins within a precast structure. Inclined plate technology is a proven method of settling sediment from water, used for decades in the potable water industry. Terre Hill adapted the inclined plate concept for the storm water environment.

Because of the innovative use of technology the Department of Environmental Protection has encouraged the development of Terre Kleen. DEP has allowed field installations to occur within Pennsylvania for purposes of monitoring unit performance.

Terre Kleen units are located on the Route 322 project at the “Narrows” in Mifflin County. The City of Harrisburg has installed a unit at the Vehicle Maintenance Facility.

Recently, a Terre Kleen unit was installed at the Watsontown manufacturing facility of F.B. Leopold Company which processes 30,000 tons of anthracite coal to make filter media for the drinking and wastewater industry.

MANTEC and PENNTAP, programs charged with assisting Pennsylvania manufacturing companies to successfully participate in an increasingly competitive environment, were both instrumental in bringing many parties together to assist Terre Hill Concrete Products develop the product.

THCP designs, manufactures and assembles the Terre Kleen units at their precast facilities located in Lebanon and Terre Hill, PA.
