Secondary Treatment
HumeCeptor® Hydrodynamic Separator
The HumeCeptor® system is an underground, precast concrete stormwater treatment solution that uses hydrodynamic and gravitational separation to remove entrained hydrocarbons and total suspended solids ≥10 microns from stormwater runoff. It is designed to contain spills and reduce non-point source pollution entering downstream waterways.
Originally developed for constrained commercial and industrial sites, the HumeCeptor® system has been expanded to service large catchments, inundated drainage systems and high-volume emergency spill events. It is ideally suited to hardstands and wash bays, car parks, shopping centres, industrial facilities, petrol stations, airports and major road infrastructure.
Independently tested and installed in over 30,000 projects worldwide, HumeCeptor® provides reliable and effective secondary stormwater treatment for space-constrained sites.
