Engineering Standards Framework

All extensions or renewals to our water and wastewater systems must be designed and constructed in accordance with our engineering standards.

Current standards​

  • ​Control systems: This section is under development.​

Standards ​for comment

There are currently no standards for comment. 


We have reviewed our processes relating to new developments and connections to our network to enable qualified contractors to self-certify their work.

We are introducing compliance statements from 1 July, 2017 to provide a consistent system for ensuring all work carried out on our network meets Watercare’s engineering standards.

Use of the statements will become mandatory from 1 July. We will provide support and advice as needed to ensure a smooth transition to the new system.

More information is available here: Compliance Statement Policy

Compliance Statement Forms:

Pl​​ease refer to thesFrequently Asked Questions.

Construction monitoring

Construction activities with a single level of complexity or simple monitoring requirements follow the IPENZ/ACENZ monitoring guidelines.

Complex construction work or works with a variety of activities and disciplines would benefit from using the Watercare Risk-based Construction Monitoring Framework​. The framework is currently a working draft and you can contact Watercare's construction delivery, site engineering manager at standards@water.co.nz​ for assistance.

Where to send your forms

New developments

From 1 July, completed CS1 and CS2 forms will need to be included as part of your Engineering Plan Approval application to Auckland Council.
