Who owns the sewer pipe on your property in Sydney?

It is not the front fence. In Sydney Water's area your pipe runs to the point of connection, which can be beyond the boundary or even under the road.

Key takeaways

In Sydney Water's area you own all your wastewater pipes and fittings up to and including the point of connection to Sydney Water's system.
The dividing line is the point of connection, not the boundary. Your private pipe can run beyond the fence, across a neighbour's land or under a public road.
Sydney Water owns the junction and the main, but you are responsible for clearing tree roots that get into the junction at your point of connection.
Sydney Water's collapsed-pipe program helps only in narrow cases: a residential pipe more than 25% collapsed under a road or hard footpath that can't be relined.
