Wellington City Council's (WCC) chief infrastructure officer Tom Williams has quit.
The role is a critical one in the council's Executive Leadership team as Williams oversees things like transport, resilience, and the city's crumbling water infrastructure.
His resignation comes as Wellington Water is about to undertake the biggest capital works programme by far in its history to try and get on top of a situation that's spiralling out of control.
In an email sent to all councillors this afternoon, which the Herald has obtained, WCC chief executive Barbara McKerrow announced Williams was leaving next month.
"Tom has assessed his capacity to lead the considerable and increasing level of delivery required in this role against being a dedicated solo-father of two young children every second week.
