EnviroBasin®
Hydro Dynamic Separator


The EnviroBasin® is a revolutionary stormwater separator.

The innovative all-in-one precast water quality inlet is a catch basin installed to capture and treat stormwater runoff at the source, removing sediment and debris before it reaches local water bodies.

The EnviroBasin® is a certified trash capture device and has the equivalent performance of an HDS.

EnviroBasin® is simple to incorporate into any infrastructure project and is supplied as a manufactured product. The integrated nature and benefits of the device reduce concrete, pipework and maintenance, conserving space and saving contractors time and money.

EnviroBasin™ is the ultimate pre-treatment solution for LID, rain gardens, tree cells and urban green infrastructure.

SIGNIFICANT COST SAVINGS

Using the EnviroBasin® instead of traditional HydroDynamic Separators (HDS) reduces the number of stormwater assets installed and maintained, providing significant savings to the land developer and the end-user.

PLUG AND PLAY

The EnviroBasin® is a
pre-manufactured and easily handled device saving the drainage contractor time and expense in installation.

EASY TO MAINTAIN

The system is easy to maintain and the EnviroBasin®’s unique enhanced storage sump capacity extends vactor truck maintenance requirements to once every
two-to-three years.

PROVEN PERFORMANCE

The EnviroBasin® received ISO 14034 verification in 2021, obtaining over 60 per cent removal of suspended sediment.

The EnviroBasin® is a catch basin and separator housed in a single unit that collects, treats, and conveys stormwater into the stormwater network.

  • Alternative to catch basin or end of line HDS
  • Efficiently conveys peak stormwater flows without resuspension.
  • The EnviroBasin® is available in a variety of sizes and configurations and is ideal pre treatment to green infrastructure and LID
  • The EnviroBasin® is compact and can be applied in tight urban spaces where there are space constrains.
