Underground construction phase underway
Yesterday, guests including Auckland Mayor Phil Goff and councillors engaged in a ceremonial dig to celebrate the Central Interceptor officially entering its underground construction phase. The dig, also known as a sod turning, took place at our Māngere pump station site. The shaft at Māngere is being constructed by our impressive hydrofraise machine that will go 50-metres underground to create the deepest diaphragm wall in New Zealand history.
Following his involvement in the ceremonial dig, Mayor Goff said, "The Central Interceptor is one of the most significant infrastructure projects in Auckland. Together with Watercare and Auckland Council’s other projects in Auckland’s western isthmus, it will substantially improve water quality and reduce wastewater overflows by at least 80 per cent, while providing for population growth in the city.”
