Inline Hydrodynamic Separator Unit, 96" Concrete Manhole

Built with durable precast concrete, the JDS hydrodynamic separator also captures total suspended solids (TSS), oil, grease, and other total petroleum hydrocarbon pollutants. Captured pollutants are retained without scouring, even under high flow bypass conditions. Capable of treating flows from 0.7 to 72 cubic feet per second, the JDS Hydrodynamic Separator is certified and approved by various agencies.

Jensen Precast offers design-build solutions with hydrodynamic separators, detention and infiltration reservoirs, biofiltration systems, oil/water separators, sedimentation systems, diversion structures, drywells, and pump stations.

Stormwater management systems are precast concrete structures designed for the pretreatment, detention, retention, infiltration, and/or reuse of urban stormwater runoff. Engineers, contractors, and government agencies depend on our expertise in building the most advanced stormwater systems available for volume control, low impact development, and green infrastructure outcomes using best management practices.
