An optional inbuilt pump chamber provides Queensland developers with an efficient, compact solution that reduces installation time and cost.
15-year industry warranty
We stand by our anaerobic baffled reactors with a 15-year industry warranty that gives you confidence long after installation.
Collection wells
Custom-made 4,000L – 82,000L
Effective sewage collection is critical for compliance with Council regulations across Brisbane and greater Queensland. Collection wells do not treat sewage; they merely store it. Once full, the collection well or holding tank is emptied and treated at another location. This is a key way collection wells differ from septic tanks, which discharge partially treated sewage (called effluent) into the soil for final treatment through an outlet.

Corrosion-proof for peace of mind
Zero rust or deterioration in Brisbane’s humid conditions, outlasting competitors by decades with virtually no maintenance.
Complete leakproof protection
Our seamless one-piece construction guarantees no risk of contamination leakage, ensuring total protection for Queensland’s sensitive ecosystems.
Straightforward lightweight installation
Lighter than concrete yet exceptionally strong, our collection wells significantly reduce installation time and cost for Brisbane’s construction sector.
15-year industry warranty
We stand by our tanks with a 15-year industry warranty that gives you confidence long after installation.
Pump chambers
Custom-made 6,800L – 82,000L
Brisbane developers can’t afford wastewater management failures. Our heavy-duty fibreglass pump chambers are built to perform reliably in even the most challenging conditions and complex sites. The purpose of a pump chamber is to distribute effluent wastewater and sewage to the main sewage system. If there is no sewage system, the waste will be pumped to a sewage treatment facility, such as a septic tank system. The pump chamber can also be used for stormwater, a clear advantage during Queensland’s demanding wet season.

Reliable wastewater management
Our tanks’ robust fibreglass construction prevents leaks and structural issues, ensuring dependable operation throughout Brisbane’s seasonal weather changes.
Versatile applications
Ideal for both wastewater and stormwater management in Brisbane’s varied development environments.
Easy installation
The pump chambers’ lightweight design simplifies installation for Brisbane contractors, saving time and reducing costs across projects.
15-year industry warranty
We stand by our tanks with a 15-year industry warranty, which gives you confidence that your investment will last long after installation.

Septic tanks frequently asked questions
How often should my septic tank be pumped?
A general guideline is every 3 to 5 years, but some systems may require more frequent pumping.
What should I NOT put down the drain?
Certain items can damage the septic system and should be avoided.
These include:
- Greases, oils, and fats: These can solidify and clog pipes and tanks.
- Household chemicals: Such as bleach, paint thinners, and pesticides can kill the beneficial bacteria in the system.
- Solids: Non-degradable items like diapers, wipes, and feminine hygiene products can block the system.
What if my septic system smells?
If you smell a strong, foul odour, it could indicate a problem with the system, such as a blockage or a buildup of harmful gases. Contact a septic system professional immediately.
Are septic tanks environmentally friendly?
Yes, septic systems use natural bacteria to break down household waste.
How do I care for my septic system?
Proper care includes:
- Avoiding flushing prohibited items: This protects the beneficial bacteria and prevents blockages.
- Regularly pumping the septic tank: This removes sludge and keeps the system functioning properly.
- Proper venting: Ensures proper gas release and prevents odours.
- Regularly inspecting and maintaining the system: This can help identify and address potential problems early on.
