We are Sydney Water listed providers for sewer drainage services in South West Sydney such as Sewer Pegouts, Sewer Property Connection Points and Sewer Deviations.

If your South West Sydney development is affected by the position of a sewer main, it may be possible to deviate or relocate the sewer.

A sewer deviation or diversion may be required when a new development, building, property extension or subdivision conflict with an existing sewer main. All Line Plumbing are accredited Sydney Water listed providers and are qualified to divert existing sewer mains safely and correctly in South West Sydney.

An upgrade to a sewer main may also be required for old clay or cast iron pipes or if the pipe is broken or in a deteriorated state. Pipes will need to be replaced using PVC pipes by a Sydney Water accredited and listed constructor such as All Line Plumbing and may also require to be concrete encased to protect the Sydney Water sewer main.

Concrete sewer encasements in South West Sydney offer a maintenance-free solution for enhancing the durability and longevity of Sydney Water assets.

Sewer Encasement Process

All Line Plumbing will usually liaise with a Water Servicing Coordinator (WSC) or engineer and install an approved design. The most common sewer encasement process is:

1. Approval: The works will need to be approved by a Water Servicing Coordinator (WSC) who is accredited by Sydney Water.
2. Excavation: Excavate the existing sewer main.
3. Pipe Preparation: Renew or replace the pipe and install support and strap down the pipe, so the pipe does not float while installing the concrete.
4. Inspection: Inspection and approval by the WSC or engineer.
5. Pouring of Concrete: Concrete will fully encapsulate the sewer main.
6. Backfilling: Backfill area and compact trench as required
7. Work as Constructed Documentation: submission of the Work As Constructed information to the project's Water Servicing Coordinator.
