Frequently Asked Questions

  • What is the difference between a septic system and a wastewater treatment system?

    A septic system is a basic form of on-site waste management where solids settle in a tank and liquids disperse through a drain field. It relies heavily on natural soil filtration. A wastewater treatment system, on the other hand, uses mechanical and biological processes to break down waste more efficiently. This results in cleaner, reusable water that can often be used for irrigation, depending on regulations. Treatment systems are more advanced, require scheduled servicing and are often recommended for properties with poor soil conditions, limited space or higher household demand.

  • How do I know if my septic or treatment system is failing?

    Common signs include slow drains, unpleasant smells around the tank or yard, wet or soggy patches above the absorption area, gurgling pipes, system alarms, backup into household drains or unusually fast grass growth over the drain field. Failing systems can cause environmental contamination, structural issues and ongoing drainage problems. Early assessment is important, as some failures can be repaired through pump-outs, component replacements or restoring aeration — while others may need a full system upgrade.

  • How often should a septic tank or wastewater system be serviced?

    Most septic tanks need pump-outs every 3–5 years, depending on household size and usage. Wastewater treatment systems generally require servicing every 3–6 months to comply with council regulations and ensure the treatment process is functioning correctly. Regular maintenance allows technicians to check aerators, pumps, filters, alarms and sludge levels before problems escalate. Skipping services can lead to expensive repairs, system failures, odours and breaches of local health requirements.

Specialised Systems for Businesses & Rural Properties

Larger sites require more robust and adaptable wastewater solutions, and choosing the right system can have a major impact on day-to-day operations. Commercial options range from permanent poly-tank sewage treatment setups to skid-mounted plants, containerised systems, rental units and advanced Membrane Bio Reactor (MBR) technologies designed for high-performance treatment. Options such as commercial pump stations, underbelly tanks, water treatment units and marine wastewater systems ensure properties of all sizes have reliable and compliant waste management. With the correct system in place, businesses can manage higher volumes, improve efficiency, reduce environmental impact and maintain smooth, uninterrupted operation.


These solutions are available across a wide service area including Junee, Coolamon, Temora, Young, Cootamundra, Gundagai, Tumut, Tumbarumba, Batlow, Narrandera, Leeton, Griffith, Darlington Point, Coleambally, Jerilderie, Barellan, West Wyalong, Barmedman, Grenfell, Howlong, Yarrawonga, Tocumwal and Cobram. Whether you’re upgrading an older setup or planning a system that can grow with your site, tailored wastewater solutions help ensure long-lasting, dependable performance.

Residential Systems

Residential wastewater and septic systems need to be dependable, efficient and suitable for the property they serve. Homeowners rely on systems like wastewater treatment units, greywater recycling, septic tanks and grease traps to manage everyday household waste safely and compliantly. A well-designed residential system helps reduce odours, prevent blockages, improve water use and protect the home’s surrounding environment.


Many properties also benefit from integrating rainwater tanks, giving households more control over their water supply and helping reduce long-term utility costs. Regular servicing keeps pumps, aerators, filters and internal components in good working order, ensuring the system continues to perform at its best. With the right setup and ongoing care, residential wastewater systems can deliver reliable operation for years while meeting council standards.

Residential Pump Stations

Some homes need additional support to move wastewater efficiently, especially when the property sits below the main sewer line or has tricky gradients. Residential pump stations are designed to keep flow consistent and prevent system overloads or blockages. These systems safely transfer wastewater from the home to the appropriate treatment point, using reliable pumps, durable tank materials and built-in safeguards to prevent failures.



Low-pressure sewer pump stations are ideal for properties on uneven ground or rural blocks where traditional gravity-fed systems aren’t suitable. With regular checks and professional servicing, homeowners can expect steady performance, reduced system pressure and fewer drainage issues over time. Proper installation and maintenance ensure wastewater moves smoothly and reliably from the home to its treatment stage.

Commercial Sewerage

Commercial sites often require more advanced sewage treatment solutions due to higher wastewater volumes and stricter performance requirements. Options such as permanent poly-tank treatment systems, skid-mounted plants and containerised units provide flexibility for different industries and site layouts. More complex operations may benefit from Membrane Bio Reactor (MBR) technology, offering exceptional treatment quality and efficiency for high-demand environments.


Rental systems are available for temporary operations, construction sites or remote setups that need short-term wastewater management. Marine wastewater products provide solutions for vessels and river-based operations that need compact, reliable systems with strong performance. Regardless of the application, commercial sewerage solutions are designed to meet compliance standards, operate efficiently under pressure and provide long-term, dependable performance.

Commercial Water

Effective commercial water treatment ensures businesses have access to clean, safe and reliable water tailored to their operational needs. These systems help remove impurities, treat incoming water supplies and support processes that require consistent water quality. From filtration to purification and specialised treatment options, commercial water systems are built for industries with high water use or strict safety requirements.


Properly installed systems can reduce equipment strain, improve operating efficiency and prevent contamination issues that can disrupt business activities. With routine maintenance and performance monitoring, commercial sites can maintain confidence in their water supply and ensure their systems continue delivering dependable results throughout daily operations.

Commercial Pump Stations, Traps & Tanks

Commercial properties often rely on robust pump stations, grease traps and wastewater tanks to support high-demand operations. Commercial pump stations help move wastewater from points of use to treatment areas, ensuring reliable flow even across larger sites or challenging terrain. Grease traps play a crucial role in preventing fats, oils and solids from entering the drainage system, making them essential for kitchens, food processing, hospitality and industrial settings.


Underbelly tanks and other wastewater storage solutions provide secure, durable space for holding or processing waste before it is treated or removed. These systems are built to withstand heavy use, meet compliance requirements and provide practical solutions for businesses that need efficient, long-lasting waste management.
