Regional priorities
Wellington Water takes a regional approach to our work. That means we take into account what’s best for the whole region as we plan and advise our client councils on managing and developing our water network. After all, pipes, rivers and streams span the region, and our citizens live, work and play across the region, too. Read more
Drinking water
We supply about 140 million litres (ML) of water per day (on average) to Upper Hutt, Lower Hutt, Porirua and Wellington. Read more
Stormwater
The stormwater system is an underground network of pipes that drains the rain off of our roads, footpaths, and from our gutters, and diverts it into our streams, rivers and eventually out to sea. Read more
Wastewater
Every day we deliver safe drinking water to your home through our drinking water network. Once used, this water leaves your home as ‘wastewater’, through your plumbing and into the public wastewater network. Read more
Emergency water
Wellington’s water supply network is vulnerable. After a significant earthquake many parts of our region may be without water for more than 100 days. Read more
