Once the water has been collected at the intakes from the rivers, or is drawn from the aquifer, it enters a treatment plant.
There are four treatment plants around the metropolitan Wellington region, owned by Greater Wellington Regional Council and four treatment plants in South Wairarapa, owned by South Wairarapa District Council.
Learn more about the treatment plants in Wellington and South Wairarapa on the pages below.
Once the water has gone through the treatment process it is distributed along the drinking water network.
Wellington Water hosts a number of group tours throughout the year of the treatment plants in Wellington. If you are interested in having a group tour, please email firstname.lastname@example.org.
