Our major projects
Over the next decade we are investing around $3 billion to make sure we keep delivering high quality, sustainable water services, support planned growth and protect our environment.
We’re working right across the IAWAI region to support our communities, and to make sure our plans support and align with the future needs of our neighbours.
