A database of registered drinking water sources was established in 2009 to assist with the implementation of the NES. It contains drinking water source points and drinking water treatment plants.
The database also contains some information on individual treatment plant compliance with the Drinking Water Standards for New Zealand 2022.
The database was sent to all regional councils for integration with existing regional council GIS systems. Additional information on the locations of registered drinking water sources is available from a drinking water assessor in the public health unit of your local district health board.

Note, the NES, defines human drinking water sources as a natural water body (such as a lake, river or groundwater) that is used to supply a community with drinking water. The standard applies to source water before it is treated and only sources used to supply human drinking water (and not livestock or other animals).
