The Cascade Separator™ is the latest advancement in stormwater treatment technology.

This innovative hydrodynamic separator excels in sediment capture and retention while effectively removing hydrocarbons, litter, and debris from stormwater runoff. What sets the Cascade Separator™ apart is its utilization of opposing vortices, which significantly enhance particle settling, and a unique skirt design that facilitates sediment transport into the sump while minimizing turbulence and resuspension of previously captured material.

These distinct features enable the Cascade Separator™ to effectively treat high flow rates within a compact footprint, offering an efficient and economical solution for any site's stormwater management needs.

How it works

01 Overview

02 Stormwater runoff enters Cascade

As stormwater enters the Cascade Separator™ through one or multiple inlets, it impacts the centre cylinder and is directed toward separate flumes

03 Runoff is treated

It then travels through the opposing flumes enters the centre chamber where vortices rotate in opposite directions and facilitate enhanced particle settling.

Benefits

Superior Pollutant Removal

Unique skirt design with opposing vortices ensures superior Total Suspended Solids (TSS) removal, resulting in enhanced water quality and ecosystem health.

Cost-Efficient Design Features

Accepts a wide range of inlet pipe angles and multiple inlet pipes, eliminating the need for costly upstream receiving manholes and separate grate inlet structures.
Internal bypass feature saves on the requirement and cost of upstream bypass structures, optimising project budgets.
Optional grate inlet is available to allow direct surface runoff discharge to the system and eliminate the need for a separate grate inlet structure.

Easy Maintenance & Installation Flexibility

Clear access to the storage sump provides fast and easy maintenance, minimising downtime and ensuring efficient upkeep.
Flexible design accommodates various site conditions, allowing for easy installation and ensuring adaptability to project requirements.
