Do you have one?
Many homes and businesses across the Mornington Peninsula, Frankston and the Bass Coast aren’t connected to mains sewer and instead rely on septic tanks or advanced wastewater treatment plants. While these systems are effective, they require regular inspections, maintenance, and in some cases, replacement to keep them operating safely and efficiently.
At SGT Plumbing, we specialise in both septic inspections and treatment plant installations. With over 20 years of local experience, our team understands the challenges of soil conditions, council requirements, and environmental responsibilities unique to this region.
Whether your existing septic is showing signs of failure or you’re building a new home that needs an approved wastewater system, we can provide practical, compliant, and long-term solutions.
Why Septic Systems and Treatment Plants Matter!
A septic system or treatment plant manages all of the wastewater from your home — including toilets, showers, sinks, and laundry. If the system fails, it can cause:
Bad odours around the property
Slow or backed-up drains inside the home
Pooling wastewater in the yard or paddock
Health risks from untreated wastewater
Environmental damage to soil and waterways
Regular inspections are essential to detect issues early and protect your property, family, and the local environment.
Septic Inspections & What we Look For.
During a septic inspection, SGT Plumbing will assess:
The condition of the tank or treatment plant
Whether the system is processing wastewater effectively
Any blockages, leaks, or cracks in the system
Pump and aerator performance (for treatment plants)
Drainage areas, trenches, or irrigation fields for signs of failure
We use both visual checks and specialised tools to ensure every part of the system is working as intended.
When to book a Septic Inspection
Every 12–24 months as part of routine maintenance
Before buying or selling a property not on mains sewer
If you notice smells, slow drains, or wet patches in the yard
After heavy rainfall or flooding that may affect drainage fields
When planning a renovation or extension to confirm system capacity
An inspection today can save you thousands in costly repairs tomorrow.
Treatment Plant Installs… What is a Treatment Plant?
A treatment plant (also called an Aerated Wastewater Treatment System or AWTS) is an advanced form of septic system. Unlike older septic tanks that only provide basic separation of waste, treatment plants actively process wastewater to a much higher standard.
By aerating and treating the water, these systems produce cleaner effluent that can be safely dispersed through sub-surface irrigation. Many councils across the Peninsula and Bass Coast require treatment plants for new builds, particularly in environmentally sensitive areas.
Why Choose a Treatment Plant?
Compliant with EPA and council regulations
Safer for the environment, especially near waterways or sandy soil
Better long-term performance than older septic tanks
Allows for reuse of treated water in irrigation fields
Adds value to your property by providing a modern system
