The EcoStorm Plus is a stormwater treatment system that utilizes both gravity separation and upflow adsorptive filtration. A cyclonic separator and porous concrete filter remove pollutants through sedimentation, adsorption, and chemical precipitation. The unit is equipped with a maintenance pipe allowing access to the sediment storage chamber. This pipe can also serve as an emergency overflow in heavy rainfall events when design treatment flows have been exceeded. The EcoStorm Plus is effective at removing Total Suspended Solids, Heavy Metals, Dissolved Nutrients, and other pollutants.

Treatment Targets

  • Total Suspended Solids
  • Heavy Metals

Technology Specifications

  • Standard precast units with capacity to manage typical treatment flows
  • Minimal drop requirement as compared to conventional filtration systems
  • Porous concrete filtration elements are easily replaced
  • Design flexibility allows for variability of removal efficiency based on particle size distribution, flows, and annualized or event-based designs
  • Cost-competitive single structure design reduces footprint and excavation costs
