Vortceptor®
The Atlan Vortceptor® Gross Pollutant Trap (GPT) is a SQIDEP verified, non-blocking hydrodynamic separator that has a unique screen and treatment action producing low vortex conditions. This innovative primary treatment device achieves excellent pollution removal performance and resulting high water quality outcomes.
It separates and captures gross pollutants, sediments, silt, total suspended solids, some nutrients, and oil and grease.
Features & Benefits
High-Efficiency Gross Pollutant Separation
Utilises hydrodynamic vortex technology to capture and separate sediments, silt, oil, grease, and gross pollutants effectively.
Permanent Pool Design
Ensures oil and grease are retained in a dedicated capture zone, preventing re-entrainment during high-flow events.
Optimal Flow Performance
Designed to treat stormwater runoff across a wide range of flow rates while maintaining compliance with Australian statutory water quality guidelines.
Robust Construction
One-piece fibreglass construction is lightweight, durable, and non-corrosive, ideal for long-term performance in diverse environments.
Trafficable Installation
Rated for vehicular (Class D) zones with appropriate concrete slab installation, ensuring flexibility for high-traffic areas.
Cost-Effective Installation
Delivered fully assembled to the site, reducing installation time, crane costs, and overall project expenses.
Easy Maintenance
Cylindrical shape and sloped base concentrate sediment at the centre, simplifying cleaning and reducing maintenance efforts.
Flexible Configurations
Accommodates multiple pipe sizes (standard units up to 2800 LPS for 150mm to 1800mm pipes) and can be customised to meet specific site requirements.
Stormwater Compliance
Provides reliable solutions for pollutant load reduction in urban and industrial stormwater systems, aligning with Low Impact Development (LID) principles.
Manufactured in Australia
Locally fabricated in our National FRP production facilities to meet ISO9001 Quality Standards.

Atlan Vortceptor® FAQ
What is the Atlan Vortceptor®?
The Atlan Vortceptor® is a SQIDEP-verified Gross Pollutant Trap (GPT) that uses hydrodynamic vortex separation and a non-blocking screen system to remove pollutants from stormwater runoff before they reach waterways.
The Vortceptor® is a primary stormwater treatment device that is often deployed as part of a treatment train, where it can work in unison with other stormwater assets such as tertiary filtration (AtlanFilter), Floating Wetlands, and WSUD systems.
Designed to screen stormwater pollutants and allow them to settle in a central chamber, the Vortceptor® is easy to maintain and accessible from surface level.
How does the Vortceptor® work?
The Vortceptor® combines vortex separation technology with a self-cleaning screen to capture gross pollutants, sediment, suspended solids, oil, and grease. It is a high-capacity GPT available in online and offline primary stormwater treatment configurations, with a range of flow rates to deliver hydraulic performance during storm events.
As a primary treatment device, the Vortceptor® is particularly valuable where you want to capture sediment and gross pollutants early in the treatment train or reduce pollutant loads reaching downstream treatment assets, drainage, or receiving waterways.
What pollutants can the Vortceptor® remove?
The system is designed to capture litter, gross pollutants, sediment, silt, total suspended solids (TSS), nutrients, oil, and grease from urban stormwater runoff.
Common pollutants in urban catchments include cigarette butts, Styrofoam, food packaging, plastics, and organic waste. Removing these at the source helps protect downstream lakes, rivers, and seas.
Is the Vortceptor® SQIDEP verified?
Yes. The Vortceptor® has been independently tested and verified under Stormwater Australia’s SQIDEP program, validating its pollutant removal performance.
What SQIDEP-verified treatment efficiencies has the Vortceptor® achieved?
The Vortceptor® is a SQIDEP-verified primary treatment solution with independently assessed pollutant removal efficiencies of:
- 100% Gross Pollutants (GP)
- 93% Total Suspended Solids (TSS)
- 86% Total Phosphorus (TP)
- 49% Total Nitrogen (TN)
What makes the Vortceptor® different from traditional GPTs?
Unlike many conventional GPTs, the Vortceptor® incorporates a non-blocking screen and hydrodynamic separator design that helps prevent screen blinding while delivering high pollutant removal performance.
Where can the Vortceptor® be installed?
The Vortceptor® is suitable for residential developments, industrial estates, commercial precincts, recreational facilities, shopping centres, beaches, parks, and urban stormwater networks.
Is the Vortceptor® available in inline and offline configurations?
Yes. The Vortceptor® can be supplied in both inline and offline configurations to suit site constraints, hydraulic requirements, and project objectives.
What are the maintenance requirements for the Vortceptor®?
Routine inspections and periodic removal of accumulated pollutants are recommended. The Vortceptor is accessed directly from site surface, and maintenance requirements include routine inspection which allows technicians to assess site health, device components, accumulated pollutants, access, and safety.
If left unmanaged, sediment and pollutant loads can impact hydraulic performance. The sediment and pollutant depth should be monitored, and periodically the Vortceptor should be emptied by a vacuum truck – which is scheduled according to catchment pollutant loadings and the size of the device.
What materials are used in the Vortceptor®?
The Vortceptor® is manufactured from reinforced fibreglass (FRP), providing excellent corrosion resistance, durability, lightweight handling, and long-term structural performance.
What is the design life of the Vortceptor®?
The Vortceptor® is a generational stormwater asset with a 100-year design life, helping councils and developers reduce lifecycle costs. Future proofing urban development, the design life of these devices ensures that we can develop a stormwater network that protects waterways for future genreations.
Can the Vortceptor® help meet stormwater compliance requirements?
Yes. The Vortceptor® assists engineers, developers, and councils in meeting stormwater quality objectives, Water Sensitive Urban Design (WSUD) requirements, and environmental compliance targets.
Our design team can help you design a GPT solution that meets the stormwater requirements of your site. We offer complimentary design services to ensure that the Vortceptor® is easy to specify and supports your project objectives.
