What is a Section 73 compliance certificate?

A Section 73 compliance certificate confirms a developer has satisfied requirements for Sydney water connections to adequately service new construction with water, wastewater, and stormwater services. Any time you plan to subdivide or develop land, a Section 73 compliance certificate may be required.

Our accredited Sydney water constructors will take the necessary steps to protect your existing assets during the process. This can include encasing pipes in concrete and the relocation of sewer pipes. Before you receive a Section 73 compliance certificate, you may need to install extra connections or pipes and pay developer fees. Our water services constructors will make a full listing of everything you must do in a Notice of Requirements letter. This letter is mandatory when applying for an occupancy certificate for the property with your Local Council.
