Water Carriers

The Health (Drinking Water) Amendment Act 2007 specifies that, from 1 July 2008, water carriers must be registered and their registration renewed annually. This includes transporters of drinking-water that use trucks, trailers, vessels, rail wagons and demountable tanks.

The carrier completes a paper form, which is assessed by a Drinking Water Assessor (DWA) from their Public Health Service Provider. Details include name and address, water supplies used for extraction, water tanks (trucks, trailers, separate tanks, etc) and fittings. These details are then entered in the national WINZ database. Once details are in and confirmed correct, the carrier is registered from that date.

Initial registration does not need an accompanying DWA certification.

Registration lasts one year. Within 3 months of the year ending, the carrier needs to be certificated by a DWA if they want their registration to be renewed for another year. While certification and re-registration are two different processes, in practice a DWA may complete both processes at the same time.

A list of Registered Water Carriers is publicly viewable on this website.
