Secondary STORMWATER Treatment
HumeCeptor® Hydrodynamic Separator
An underground precast concrete treatment system that uses hydrodynamic and gravitational separation to remove hydrocarbons and suspended solids from stormwater runoff, and contain spills before they reach downstream waterways.
How it works
HumeCeptor® uses hydrodynamic and gravitational separation to remove entrained hydrocarbons and total suspended solids of 10 microns and above. It is designed to contain spills and reduce non-point source pollution entering downstream waterways.
Originally developed for constrained commercial and industrial sites, the system has been expanded to service large catchments, inundated drainage systems and high-volume emergency spill events.
Key features
- Sized to achieve required water quality outcomes on an annual basis
- Proven resistance to sediment scour during high-flow events
- Captures particulate-bound nutrients with sediment
- Allows for emergency spill storage, tidal inundation and complex pipe configurations
- Fully trafficable for urban and infrastructure applications
HumeCeptor® in the field
Common questions
Entrained hydrocarbons and total suspended solids of 10 microns and above, along with particulate-bound nutrients captured with the sediment.
Hardstands and wash bays, car parks, shopping centres, industrial facilities, petrol stations, airports and major road infrastructure.
HumeCeptor® has been independently verified under NJCAT/TARP (USA) and ETV Canada protocols.
Yes. It allows for emergency spill storage and has proven resistance to sediment scour during high-flow events.
