Stormwater Treatment Systems
​
​
​
Mack Industries and Jensen Precast provide an economic solution to Stormwater Treatment.


Hydrodynamic Separators:
Capture 100% of trash and debris and treat stormwater runoff to meet agency requirements for total suspended solids, heavy metals, nutrients, total petroleum hydrocarbons, and gross pollutants with a Jensen Deflective Separator (JDS) available in different sizes and configurations.
​
With no moving parts, the JDS is uniquely able to screen trash and debris including floatables, and both neutrally and negatively buoyant materials, from storm water, all without blocking the screen. The JDS treatment solution also captures total suspended solids (TSS), oil, grease, and other total petroleum hydrocarbon (TPH) pollutants from storm water runoff. Captured pollutants are retained without scouring, even under high-flow bypass conditions.

Biofiltration Systems:
​
With an ability to treat higher stormwater flows than conventional biofiltration units, the StormVault Biofiltration System is a simple and highly versatile storm water treatment solution for meeting water quality standards as a low impact development best management practice.
​
The StormVault Biofiltration System is a simple and highly versatile storm water treatment solution. Through physical and chemical filtration, adsorption, and biological processes, StormVault Biofiltration efficiently removes Total Suspended Solids (TSS), metals, nutrients, oil, and grease from storm water runoff to meet water quality standards as a low impact development best management practice. With specially engineered filter media, the system can treat higher flows than conventional bioretention units, allowing for a smaller footprint size and lower overall costs.
