The system, explained
EcoProtector uses an inlet weir and vortex flow path to separate gross pollutants and sediment. Captured material is stored for removal during maintenance, while the high-flow arrangement allows water to pass through the system.
Explore our engineering supportHow it works
The inlet weir directs water into the vortex flow path.
Gross pollutants and sediment move into the storage chamber.
Dedicated access allows inspection and pump-out of retained material.
Where it fits
For designers & specifiers
Start with the project requirements.
We’ll help you confirm the right configuration.
Confirm gross pollutant and sediment treatment objectives.
State treatment flow and peak bypass flow.
Select pollutant storage capacity and a maintenance interval suited to the catchment.
Provide pipe sizes, orientation, invert levels and downstream constraints.
Confirm cover loading, groundwater, excavation and backfill requirements.
Provide pump-out access and request model-specific drawings and maintenance instructions.
Complete the bracketed project details and confirm the selected model with Protector.
Final dimensions, capacities and installation details are established in the approved project drawings and current manufacturer documentation.
