EnviroBasin™
Hydrodynamic Separator


The EnviroBasin™ is a revolutionary stormwater separator.

This innovative, all-in-one precast water quality inlet captures trash and removes sediment and debris before it reaches local water bodies.
‍
It is supplied as a complete structure with integrated flow-modifying components that work together to capture trash and promote sedimentation. The sump depth, deflector plate, basket position and outlet baffle are designed as a coordinated treatment system. The basket captures trash and larger debris, while the internal components manage flow to encourage finer sediment to settle in the sump.

The EnviroBasin™ is a certified trash capture device with 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.

Reduce infrastructure costs

Combining collection and treatment in one structure can reduce the number of stormwater assets your project requires. Where EnviroBasin replaces a conventional catch basin and separate downstream HDS, it reduces associated excavation, concrete, connecting pipes, and ongoing asset maintenance.

Separator treatment within the catch basin footprint

Incorporate stormwater treatment directly into the inlet location. EnviroBasin makes efficient use of available space, helping designers accommodate treatment in constrained sites and urban developments.

Accessible maintenance

Separate trash and sediment storage allows each to be maintained according to its loading. Captured trash is accessible from the surface, while accumulated sediment can be removed from the sump using a vacuum truck. Inspection and cleaning intervals depend on site conditions and pollutant loading.

ISO 14034 ETV certified badge

Independently verified performance

EnviroBasin has ISO 14034 Environmental Technology Verification (ETV) for its tested sediment removal performance. It is laboratory and field-tested in the USA with Conditional Use Level Designation- State of Washington.

WHY ENVIROBASIN?

  • Replacing a catch basin and downstream HDS unit with one EnviroBasin™reduces the number of stormwater assets
  • Meets the Trash Full Capture requirement of California Trash Amendments and delivers sediment pretreatment in the same structure.
  • A pre-manufactured, easily handled product that saves the drainagecontractor time and installation cost.
  • Simple maintenance, with separate trash storage and a large sediment storage volume.
