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.

Frequently asked questions

Individuals (e.g. sole traders) and companies (e.g. consulting engineers, civil construction contractors, project managers, registered surveyors and town planners) can apply for accreditation to become an ‘Accredited Entity’ and/or Registered Certifier.

It is anticipated that applicants will have a level of knowledge or practical experience with land development and the processes for connection to water supply and sewerage networks in South East Queensland.

There are no accreditation application fees and no charge for training provided by Unitywater.

Registered Certifiers pay fees to Unitywater as part of the package submission process.

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.
