Hydrodynamic Separation

Hydrodynamic separators from Oldcastle Infrastructure utilize an integral “flow through” high-flow bypass, an effective system for the removal and retention of sediment, debris and other pollutants from storm water runoff. Captured debris and floatables are retained even during high flows. At peak flows, excess flows breach the control weir and exit the system without impacting treatment or re-entraining captured pollutants.
