Drinking Water Database

DWO - Drinking Water Online

The Ministry of Health have funded the development of a new database, drinking Water online, to replace WINZ from the latter half of 2017. This database itself has been developed by Beca following a public tender process in 2015-16. ESR has worked closely with the Ministry and Beca and much of the Water Information New Zealand (WINZ) functionality is now available in DWO.

Because DWO can be accessed by all users through a web browser, the new system means that appropriate information is accessible immediately to suppliers and health authorities. ESR continues to have a national role in managing data and providing science-based advice to all users.

The DWO main screen is shown below:

Drinking Water Online example

Owners of networked water supplies in New Zealand who are not currently DWO users should discuss their options with a Drinking Water Assessor in their Public Health Unit of their district health board.

DWO users or potential users with questions should address them to the DWO Helpdesk

Data presented on this website is from Drinking Water Online except for the Annual Review compliance information, which was was gathered by the WINZ database system in 2017 or earlier.
