The significance of a sewer peg out in Australia

Most Sydney locals are familiar with the term sewer peg out but are not sure of what it is. A sewer peg out is a sewer survey or service protection report that helps architects and structural engineers design structures that comply with the Sydney Water requirements. 

What is a sewer peg out Sydney?

A proposed structure may be situated over or adjacent to a Sydney Water sewer main. If the owner of the structure is not aware of the sewer location, it may cause severe damage to the sewer main. The damage will result in the owner having to bear additional costs and penalties.

Architects and structural engineers aware of the sewer location will need to have their plans stamped and requirements approved by a Sydney Water accredited supplier. Many construction groups are qualified to complete all stamping processes on your behalf. So, you may take their assistance.

What is a peg out report?

A peg out report decides on the environment and location of a Sydney Water asset inside or near a proposed structure. The peg out report will assess an area and see if there is any special need relating to the Sydney Water’s sewerage foundation.

The report is prepared after a qualified technician attends a particular property site and traces the sewer main, and other related structures present within the property site. Once developed, the report clearly shows the information collected and displays the location, depth, and size of the pipeline/ structure and strata within which pipes are laid.

How long does it take to prepare a sewer peg out?

• A sewer peg out usually takes around 2 to 3 days to make. However, companies offering the service also provide emergency same-day peg outs in particular circumstances. 

• The sewer and water infrastructure in Blue Mountains, Illawarra, and Sydney, are all assets of Sydney Water. Therefore, Sydney water developed the peg out process whereby, any structural development plans are to be reviewed and stamped for approval. The report is either made by a Sydney Water Tap in operation or by a Water Service Coordinator.

• Upon completion of a Tap in the application, the report will return as either ‘application approved’ or ‘further assessment required.’ 

• In case the development is inside the zone of influence, it is a threat to the asset. Hence, the architect or property owner will be advised to contact a Water Service Coordinator (WSC). A Service Protection Report (aka sewer peg out) is mandatory in such a circumstance until further approval is granted.

• A qualified technician must use the most up to date technologies and physically locate the sewer, to ensure that the sewer is located accurately. Next, a series of measurements must be taken after finding the sewer. Finally, all the data must be processed during the on-site inspection with assistance from Sydney Water records to draft a plan that meets Sydney Water standards.

At last, a Water Servicing Coordinator will use the development plan, and the sewer peg out plans and provide advice and steps to protect Sydney Water Asset. After meeting all the guidelines, the development project will be approved.
