Combined sewerage drains
Before starting your development it's important to check if the land is serviced by a combined drain.
What is a combined drain?
A combined sewerage drain is a privately owned sewerage pipe that collects sewage from multiple properties. The sewage collected from each property is then disposed to Yarra Valley Water's sewer main via a single connection.
Combined drains are the responsibility of multiple property owners.
What does it mean for my development?
Multi lot developments
- An existing combined drain cannot be used for servicing new lots.
- In some cases, an extension of Yarra Valley Water's sewerage infrastructure may be required to enable the connection of a sewer branch.
- If you are considering developing on a combined drain you can get free servicing advice in order to make informed decisions.
Single lot developments
- An existing combined drain may be used where demolishing and rebuilding a structure without any additional land development.
- An existing combined drain may be used where extending or renovating an existing structure.
Is my land serviced by a combined drain?
There are two ways to determine if your land is serviced by a combined drain:
- Purchase a property sewerage plan (PSP). A PSP outlines the location of private sewer pipes that connect to a Yarra Valley Water sewer main.
- Purchase a property asset plan. These plans show Yarra Valley Water infrastructure (water and sewer assets) that are on or near a property.
