Network capacity in Auckland

Find out where there is network capacity in Auckland.

The map below shows where there is capacity in our water and wastewater networks and treatment plants to support new housing, and where there are capacity limitations.

In most areas where there are limitations, we are planning projects to upgrade or expand the infrastructure. The timeframes for these projects are shown in the table that accompanies the map.

A few rural areas have historic constraints that we inherited when we took over the region’s water and wastewater services in 2010. These are very small communities and we are not planning to increase network capacity in these areas.

No capacity long term

About the map

  • If you are considering building in an area with a capacity limitation, please click here before you start working on your project. The online tool will help you understand whether your project could be impacted.
  • The map focuses on capacity at a town or suburb level. Across Auckland, some individual streets may be limited due to bottlenecks in local water or wastewater pipes. We encourage you to assess the impact of your proposed development as part of your resource consent process. If a network limitation is identified, you may need to upgrade the local network. See our consents page to understand the key steps in the resource consent process.
  • We will update this map regularly.
  • While this map offers a broad overview of our network capacity, please use our GIS maps to zoom in on areas with network limitations. In GIS, click on ‘layers list’ and then ‘planning areas’.

How we support growth in Auckland

Over the next 10 years, Auckland’s population is forecast to grow by 13 per cent, adding another 215,000 people to our current population of 1.75 million.

We align our asset management planning with Auckland Council’s Future Development Strategy. This helps to ensure that we are investing in the right areas and at the right time to support anticipated growth.

This financial year we plan to invest more than $1billion in new and upgraded water and wastewater infrastructure for Auckland.

This is part of a $13.8 billion investment planned for the next decade – about half of which is for projects that support growth.

I’ve got resource consent but I don’t have engineering plan approval or a building consent. What does this mean for me?
I’m planning to build a new development in an area that appears to have no growth limitations, according to the map. Does that mean I’m fine to proceed?
I want to build a new development but have been told that no connections to the wastewater network will be available for several years. Can I build an alternative wastewater solution?
Can I pay my infrastructure growth charge early and secure my connection?
