What is a Section 73 Certificate?

If you are:

• Developing
• Subdividing land 
• Creating a dual occupancy
• Constructing a residential, commercial or industrial building
• Needing Building Plans Approved prior to obtaining a Construction Certificate from your Principal Certifying Agency or Council

and you are in the Sydney Water catchment area you are likely to need Section 73 Compliance Certificate to determine whether your development or subdivision will meet Sydney Water’s servicing requirements. These services include Water/Recycled Water and Sewer, and in some cases Stormwater systems.

You are not likely to need a Section 73 Compliance Certificate if you are constructing a house that is replacing an existing dwelling or altering/extending a house - but to determine this you should get your building plans checked and stamped at a Sydney Water office or a Quick Check outlet.

Why do I need a Water Services Coordinator (WSC)?

As Sydney Water does not accept applications directly you will need to engage a Sydney Water accredited Water Servicing Coordinator (WSC) – such as ACOR WSC Consultants Pty Ltd - to apply for your Section 73 certificate.

Applications for an extension or an adjustment to Sydney Water assets or for permanent road closures must also be made through a WSC.

A Water Services Coordinator will liaise between developers, design companies and Sydney Water. They will prepare and lodge:

• Section 73 Applications electronically direct to Sydney Water (Note: Sydney Water now only accepts electronic lodgments)
• Sewer and Water designs direct to Sydney Water for approval
• Final Project Management documentation to Sydney Water
