Our Process for New Treatment Plant Installs
Installing a wastewater treatment plant isn’t just about digging a hole and dropping in a tank — it requires planning, compliance, and long-term system design. At SGT Plumbing, we manage the entire process for you:
- Site assessment & planning – We work with our Land Capability Assessor to provide a comprehensive Land Capability Assessment (LCAs) to design a compliant system suited to your property’s soil type, slope, and usage.
- System supply & installation – We specialise in advanced secondary treatment plants, such as the Ozzi Kleen RP10 and other EPA-approved systems, sized correctly for your household.
- Council paperwork & permits – We handle all the forms, drawings, and applications so your system is approved before works begin.
- Effluent disposal solutions – From subsurface drip irrigation to alternating fields, we design disposal systems that protect both your property and the environment.
Ongoing servicing & support – New treatment plants require servicing to remain compliant with EPA standards. We offer scheduled maintenance so your system keeps running efficiently.

Common Problems We See With Old Septic Systems
Many homes across the Mornington Peninsula, Western Port Bay, and Bass Coast still rely on ageing or homemade septic systems. These older systems often fail to keep up with today’s water use and may no longer meet compliance standards.
Here are some common issues we regularly come across:
- Overflowing or failing septic tanks – Older systems can’t handle modern demand, leading to overflows, bad smells, and soggy ground.
- Homemade or non-compliant systems – Some properties still run on makeshift septic systems that don’t meet EPA standards. Councils are now enforcing upgrades.
- Blocked or failed absorption trenches – Traditional trench systems clog over time, causing slow drains and wastewater pooling above ground.
- Undersized systems – Many old tanks were built for smaller homes. Renovations or extra bedrooms can quickly overwhelm them.
- Environmental concerns – Leaking or failing systems risk contaminating local waterways, creeks, and dams, which councils and the EPA are actively monitoring.
If you’re experiencing these problems, it’s often more cost-effective to replace your septic with a new treatment plant rather than spending money on ongoing repairs.
