Metropolitan Wellington

People living and working within the boundaries of Hutt, Porirua, Upper Hutt and Wellington city councils are served by an interconnected water system. Drinking water from the Hutt Valley supplies the whole area and communities covered by different councils share the same wastewater treatment plants.

Our goal is to ensure the delivery of safe, reliable, environmentally and financially sustainable water services so the region can be resilient, restore te mana o te wai and enable new homes and the well-being of communities.
