New A1, A2, A3 and B1 certification responsibilities under the Infrastructure SEPP

14 Aug 2018
The Building Professionals Regulation 2007 has been amended to allow A1, A2, A3 and B1 certifiers to certify water and sewerage lead-in infrastructure as complying development under the Infrastructure SEPP.

What has changed under the Infrastructure SEPP?

The recently amended State Environmental Planning Policy (Infrastructure) 2007 (the SEPP) allows some low impact water and sewerage lead-in infrastructure (minor pipeline works) to be approved as complying development, rather than needing a development application.

Complying development

The development will need to comply with the general requirements for complying development and complying development certificates as per clause 20B and 20C of the SEPP.

Clause 130 sets requirements related to pipeline connections with relevant utility operator’s water and sewerage systems, pipeline dimensions and depth; land use and role of the developer.

Clause 131 sets the conditions which must be complied with. These relate to requirements for neighbour notification, earthworks, excavation, fill, demolition and compliance with requirements of the relevant utility operator.

In these clauses, ‘relevant utility operator’ means the Sydney Water Corporation or the Hunter Water Corporation.


The relevant water authority, not the certifier, assesses the pipe design against national design standards (Water Services Association of Australia Codes).

For the requirements under cl 131(2) of the SEPP:

Also, keep in mind that other approvals (e.g. road opening) may be needed.


Certifiers with questions about a particular application should contact:

  • the relevant Sydney Water Case Officer (the developer, or Water Servicing Coordinator, who engages the certifier will have the Case Officer's contact details)
  • Catherine Hartley at Hunter Water: or (02) 4979 9574.
