Sedimentation Systems

JPHV

Jensen Precast high-velocity stormwater interceptors (JPHVs) have a solid history of innovative, cost-effective stormwater pollution control. JPHVs are designed to capture and retain sediment, trash, oil, and grease found on streets, parking lots, and other impervious surfaces. These versatile interceptors can be configured inline or offline, with or without bypass, providing for ultimate flexibility.

How It Works

The use of sedimentation interceptors for pollutant removal is based on the concept of slowing the flow velocity through the box, thereby allowing solids, trash, debris, and associated pollutants to be removed from the stormwater.

As stormwater enters the box, the hanging baffle removes any floatables, such as trash, debris, oil, and grease. As water encounters the floor baffle, flow velocity decreases, allowing heavier particles such as sediment to settle. In addition to decreasing flow velocities, the baffles impede particle movement. As pollutants strike the baffles they begin to rise or settle. Sorbent mats and a specialized outlet plumbing configuration further prevent pollutants from exiting the interceptor.
