IAWAI Launches $200 Million Southern Wastewater Treatment Plant in Hamilton
WATER INFRASTRUCTURE & DESALINATION
IAWAI has initiated the $200 million Southern Wastewater Treatment Plant project to alleviate wastewater capacity constraints for Hamilton, Waikato, and Waipā. As part of the Government's Local Water Done Well framework, IAWAI was formed to oversee water services and large infrastructure projects.
The facility will address population growth pressures and support development in various areas, including Hamilton Airport. A preferred site has been identified, and Hamilton City Council has allocated $7 million for planning and land designation, with construction expected to begin within the next decade.
