Projects around Auckland

At any one time we have multiple projects happening across Auckland increasing the capacity and building resilience of our water and wastewater networks. As Auckland continues to grow we must expand our infrastructure to meet these housing needs. Also, we must continually maintain our existing infrastructure to ensure a safe and robust supply network.
