What is a Section 73 Certificate?

A Section 73 Certificate is required when a development or subdivision requires servicing of sewer and water making an impact on Sydney Water’s system. This may include, but is not limited to:

  • Dual occupancies;
  • Subdivision by Torrens, Community, Strata and Stratum Title;
  • Medium density (multi-unit) residential development;
  • Industrial, commercial and special use developments;
  • Construction of mixed-use developments.

The sooner you start the process of obtaining your Section 73 Certificate, the better. There may be infrastructure works to be carried out so to avoid any unnecessary delays in the Section 73 Certificate being issued it is important to contact us now so we can get your application under way.


There are many large-scale projects that help improve our everyday life with upgrades to existing systems like motorways, rail corridors and connecting infrastructure (tunnels). These often impact existing services and assets which is where many adjustment cases are formed.

Specialising in the design and coordination of sewer and water adjustments in response to these upgrades, RAR is equipped with the knowledge and expertise required to assist contractors in the successful delivery of large-scale infrastructure projects.
