  • Site survey plan by a Registered Surveyor.  All levels to Australian Height Datum (AHD).

  • Payment of the Building over Sewer Plan checking fee.  Refer to Shoalhaven Council’s Fees and Charges.

All works relating directly to the sewer infrastructure, as specified in the Development Application Notice and Building over Sewer approval are required to be carried out in the presence and to the satisfaction of Shoalhaven Water’s inspector.

Inspection for any works should be arranged and confirmed at least 2 working days in advance and will be at the cost of the developer/applicant.

Points to consider:

  • Sewer infrastructure must be suitably protected from damage, and to enable maintenance, minimum clearances are required to be maintained from proposed structures.
  • Unrestricted access to all manholes, lampholes and/or maintenance shafts and junctions shall be provided and maintained at all times.
  • Concrete encasement of the sewer main is required for the protection of the affected pipe and any associated infrastructure due to the loss of access.
