Sewage Treatment Systems

With decades of industry experience, GPS Environmental is one of Australia’s longest established specialists in wastewater treatment systems.

We provide:

• Supply of approved sewage treatment systems
• Professional installation services
• Scheduled maintenance and servicing
• System upgrades and replacements

All of our systems comply with Australian regulatory standards and are available in both concrete and poly construction, depending on site requirements and project specifications.

Longevity in this industry is not accidental. It reflects consistent performance, regulatory compliance and systems that continue to operate reliably in demanding Australian conditions.

In many parts of Australia, properties are located outside reticulated sewer networks. In these unsewered areas, local governments require householders to install individual sewage treatment systems to manage domestic wastewater.

A domestic sewage treatment plant treats wastewater generated from:

• Toilets
• Bathrooms
• Kitchens
• Laundries

Properly designed systems treat and clarify wastewater before safe discharge or land application, protecting groundwater and the surrounding environment.

The Department of Natural Resources authorises household systems when they are proven to be effective, and local councils approve their use within their jurisdictions. GPS Environmental supplies systems that meet these requirements, helping property owners navigate compliance with confidence.

Our domestic sewage treatment systems are designed to be:

• Compact and efficient
• Low maintenance
• Energy conscious
• Suitable for Australian soil and climate conditions

Beyond residential applications, GPS Environmental delivers commercial sewage treatment systems for a wide range of industries and project types.

Commercial systems are commonly required for:

• Caravan parks
• Remote worker accommodation
• Industrial facilities
• Schools and community buildings
• Mining and resource sites
• Defence and infrastructure projects

Commercial sewage treatment systems must handle higher volumes, fluctuating loads and more complex operational demands. We use current, up-to-date technology from our exclusive partners to ensure reliable treatment performance and long-term durability.

Each system is carefully sized according to projected occupancy, wastewater volumes and local discharge requirements.

Australia presents unique wastewater challenges, including variable soil types, climate extremes and remote project locations.

GPS Environmental designs sewage treatment systems in Australia that account for:

• High temperatures and harsh environments
• Rural and remote installations
• Limited infrastructure access
• Strict state and local government approval processes

Regardless of your project’s location, our team is equipped to support installation nationwide. We regularly work in remote areas and travel as required to ensure systems are delivered, installed and commissioned correctly.

Timely delivery and professional implementation are core to our approach.

A sewage treatment system processes domestic or commercial wastewater through several stages to remove solids, organic matter and harmful contaminants before discharge.

Typical treatment stages include:

• Primary settlement to remove solids
• Biological treatment to break down organic material
• Clarification and separation
• Final treated effluent discharge or irrigation

Advanced wastewater treatment systems may include aeration chambers, filtration units and disinfection processes depending on regulatory requirements and site conditions.

The goal is consistent: safe, compliant wastewater management that protects public health and the environment.

GPS Environmental supplies sewage treatment systems in both concrete and poly configurations.

Concrete systems are often selected for:

• Long-term durability
• Larger commercial installations
• High load-bearing areas

Poly systems offer:

• Lightweight installation
• Corrosion resistance
• Flexibility in tight or restricted access sites

Our team will assess your site conditions, access constraints and regulatory obligations to recommend the most suitable solution.

In unsewered areas, approval for sewage treatment systems is typically managed by local government authorities. Systems must demonstrate proven treatment performance and meet state-based health and environmental regulations.

GPS Environmental works closely with councils and regulatory bodies to ensure:

• Approved system selection
• Correct installation practices
• Ongoing servicing compliance
• Documentation support where required

Our experience simplifies what can otherwise be a complex approval process.

A sewage treatment system is not simply installed and forgotten. Regular servicing is essential to maintain treatment efficiency and regulatory compliance.

GPS Environmental provides:

• Routine maintenance programs
• Inspection and performance checks
• Component replacements
• System troubleshooting

Ongoing servicing ensures your wastewater treatment system continues to operate efficiently year after year.
