Take a closer look at two recent Mornington Peninsula septic to sewer projects and see what’s involved from start to finish.
DCG Plumbing recently completed a septic to sewer connection in Sorrento, upgrading this property from an ageing septic system to mains sewer. With existing services and a freshly landscaped backyard throughout the site, careful planning was required to minimise disruption and complete the works safely.
DCG Plumbing recently completed a septic to sewer connection in Capel Sound, upgrading the property from an ageing septic system to mains sewer. One of the main challenges on this project was the extremely sandy soil conditions, which required careful excavation to prevent trench collapses and maintain safe working conditions throughout the job.
Not every property can immediately connect to the mains sewer network. Eligibility depends on whether sewer infrastructure has been installed in your street and whether your property can physically connect to the system. Across parts of the Mornington Peninsula, sewer upgrades have made many homes in suburbs such as Rye, Blairgowrie, Sorrento, Portsea, Tootgarook and St Andrews Beach eligible for connection. A licensed plumber can assess your property and help confirm eligibility through South East Water before planning the connection.
Once a property connects to the sewer system, the existing septic tank must be properly decommissioned. This normally involves pumping out all waste from the tank, disconnecting the tank from the house drainage, and backfilling the tank with sand or approved material so it cannot collapse or create future ground movement. The exact method can vary depending on whether the septic tank is plastic or concrete and the specific site conditions on the property.
If the sewer connection point has already been installed by the water authority, the plumbing work itself can often be completed within a day. However, the overall timeline can vary depending on factors such as water authority scheduling, septic tank pump-out coordination, property access, excavation requirements, and compliance inspections. After assessing the property and confirming approvals, a licensed plumber can provide a clearer timeframe for the connection.
Once a property has been connected to the mains sewer network and the septic tank has been properly decommissioned, the home no longer relies on a septic wastewater system. Wastewater flows directly into the sewer infrastructure managed by the water authority. This means homeowners no longer need to organise septic tank pump-outs or ongoing septic system maintenance.
For many Mornington Peninsula homeowners, connecting from septic to sewer offers several long term advantages. Sewer systems typically require less maintenance than septic systems, provide more reliable wastewater management, and can increase property value. Sewer connections can also simplify approvals for renovations, extensions, and new plumbing work. As sewer infrastructure continues expanding across the peninsula, many homeowners are choosing to upgrade from older septic systems to modern sewer connections.

A septic to sewer connection is a regulated plumbing process that must be completed in the correct sequence to meet Victorian compliance requirements.
In most cases, the process begins when a homeowner contacts DCG Plumbing to assess their existing septic system and determine whether a sewer connection is available. Some homeowners may already have arranged an on-site assessment with South East Water, who confirm connection eligibility and the most suitable connection method.
The typical process includes:
Once approved, South East Water issues connection pricing, which in many cases can be government-subsidised and added to the homeowner’s quarterly water bill to be paid off over time.
Septic to sewer connections require coordination with specific governing bodies to ensure all work is legally compliant.
The two primary authorities involved are:
DCG Plumbing manages all required compliance documentation, ensuring certificates and testing are correctly lodged against the property.
All new sewer drainage must be installed and tested in accordance with Australian plumbing standards before it can be approved.
Key compliance requirements include:
An inspection may be carried out by an authorised inspector. Inspections are random and not guaranteed for every job.
If an inspection is scheduled:
Once testing is complete, DCG Plumbing finalises certification and submits all required documentation.
Correct decommissioning of the existing septic tank is a critical compliance requirement and varies depending on tank type.
The process generally includes
Tank-specific methods
Must be fully backfilled with sand or approved material to prevent collapse or movement once decommissioned.
May be backfilled or modified to allow groundwater movement, depending on location and conditions.
In coastal and sandy areas of the Mornington Peninsula, tanks are typically fully backfilled to ensure long-term ground stability.
Installation timeframes depend on whether the sewer connection point has already been installed by South East Water.
In most cases:
DCG Plumbing provides clear timeframes upfront so homeowners understand what to expect.
Installation timeframes depend on whether the sewer connection point has already been installed by South East Water.
Once the sewer connection is completed:
There is no ongoing maintenance required for the sewer connection itself.
For properties connected to a low-pressure sewer system, pumps and sewer assets remain the responsibility of South East Water. If a pump fault occurs, homeowners simply contact South East Water directly for repair or servicing.
