How it works

Unitywater’s new accreditation and certification system will allow entities and individuals to be accredited and registered:

  • as being competent to assess connections applications
  • to certify that engineering designs and constructed assets are compliant with the relevant connections approval requirements and prescribed standards.

The accreditation and certification system applies to most connection applications that do not include trunk infrastructure or is a standard water or sewer connection. 

The new system was implemented on 1 July 2017 and will run in parallel with the current Unitywater Connections Application process until 30 June 2019.

From 1 July 2019, all aspects of non-trunk water supply and sewerage connections applications, including assessment of connections applications and design, construction and handover of donated assets to Unitywater, will be managed by accredited entities and individuals.

The accreditation process

Accreditation application rounds will be conducted once a year by Unitywater to establish and then maintain a pool of Accredited Entities and Registered Certifiers that provide certification services to the development industry. If successful, your initial registration will be for a period of 2 years. Renewals will be subject to satisfactory performance.

The 2017 round of applications is now closed

Unitywater is currently assessing applications and will advise applicants if they have been successful by the end of September.

Successful applicants will then be invited to register for training by early October.

Training will be conducted in October and November and those who successfully complete all training modules will be appointed in December.

Please check back here regularly for updates on future application rounds.

Between 1 July 2017 and 30 June 2019, we will operate our current development services business as usual in conjunction with the Accreditation and Certification System.  During this time applications for connections will continue to be accepted by Development Services. This will provide time for the appointment of a sufficient number of accredited entities and registered certifiers to meet development demand.
