Biosecurity & Quarantine Washdown Systems
Integrated biosecurity and quarantine washdown systems designed for ports, freight terminals, container yards, agriculture, mining, government facilities and industrial operations across Australia.
Aqua Bays Australia designs and delivers complete washdown infrastructure that helps remove soil, organic matter, weeds, pests and contaminants while supporting environmental compliance and efficient site operations.
Purpose-built for high-risk biosecurity environments
- Permanent heavy vehicle washbays
- Integrated wastewater treatment
- Stormwater diversion and trade waste control
- Collection pits, pumps, tanks and separators
Australia's First Line of Defence
Australia maintains some of the world's strictest biosecurity standards to protect agriculture, native ecosystems and industry from harmful pests, diseases and invasive species.
Purpose-built washdown infrastructure helps facilities safely remove contamination before equipment enters controlled areas, moves interstate or returns to operational service.
Whether referred to as an AQIS washbay, quarantine washdown facility or biosecurity washdown system, the objective remains the same: prevent contamination from spreading while managing wastewater responsibly.

Complete Biosecurity Washdown Systems
Effective biosecurity requires far more than a pressure washer. Aqua Bays Australia combines civil works, plumbing, wastewater management and environmental controls into one coordinated solution.
Washbay Infrastructure
Permanent concrete washbays, modular and relocatable washbays, drive-through wash lanes and heavy vehicle wash facilities.
Vehicle Cleaning Systems
Wheel wash systems, undercarriage wash systems and high-pressure wash equipment for operational biosecurity cleaning.
Wastewater Capture
Collection pits, pump stations, holding tanks, trade waste infrastructure and wastewater treatment systems.
Environmental Controls
Oil-water separators, stormwater diversion systems, monitoring, controls and maintainable environmental management.
Applications
Designed around each site's operational requirements, contamination risk, environmental obligations and long-term maintenance needs.
Freight & Logistics
Facilities for interstate freight, heavy vehicle fleets, distribution centres, container transport and cross-border operations.
Agriculture
Reduce transfer risk from soil-borne diseases, weed seeds, livestock contaminants, crop pathogens and organic material.
Mining & Resources
Heavy-duty washdown facilities for equipment moving between mine sites, states and territories, export facilities and international projects.
Government & Public Infrastructure
Suitable for biosecurity inspection facilities, government depots, border operations, emergency response fleets and local government works depots.
Typical Biosecurity Washdown Process
A successful system follows a controlled process that captures contaminants while protecting the surrounding environment.

Environmental Compliance
Biosecurity washdown infrastructure must safely manage contaminated wastewater rather than simply washing contaminants into the stormwater system.
By integrating environmental controls from the beginning, facilities can achieve a more practical, reliable and maintainable solution.
Integrated environmental solutions
- Trade waste collection and holding tanks
- Stormwater diversion and isolation valves
- Collection pits, pump stations and spill containment
- Oil-water separators and water treatment systems
- Environmental monitoring and water recycling opportunities

Frequently Asked Questions
What is an AQIS washbay?
An AQIS washbay is a washdown facility used to remove contaminants from vehicles, machinery and equipment before entering or leaving biosecurity-controlled areas. Although AQIS no longer exists as a separate agency, the term remains widely used throughout Australia.
What industries require biosecurity washdown facilities?
Common industries include ports, freight and logistics, agriculture, mining, construction, government, defence and import/export operations.
Can contaminated wash water be recycled?
In many cases, yes. Depending on the level of contamination and regulatory requirements, treated water may be suitable for reuse within the washdown system.
Do biosecurity washbays require wastewater treatment?
Most facilities require controlled collection and management of contaminated wash water. The appropriate treatment process depends on the contaminants present and local authority requirements.
Can existing facilities be upgraded?
Yes. Many existing depots can be upgraded with improved drainage, wastewater collection, stormwater diversion, pump systems and environmental controls without constructing an entirely new facility.
