Taumata Arowai will also have an oversight role in protecting the environment from the impacts of wastewater and stormwater. ("Three Waters")
The Three Waters Reform is a separate initiative to consolidate management of Council water supplies into four entities. It doesn't affect private water suppliers.
If you are responsible for a Council supply, please contact us for specialist advice. We have extensive public health experience with Council supplies, from small UV plants, standard coagulation/flocculation plants, to Watercare’s membrane filtration plant treating the Waikato River water for Auckland’s supply.
