It's understood a mayoral task force is being mooted as Wellington City Council moves into damage control over what some councillors are calling a water crisis.

An urgent meeting was held yesterday after two major wastewater pipelines failed within a month of one another and a string of burst water mains, which left hundreds of residents without water in their homes.

Today, it's understood a mayoral task force is being discussed.

Furthermore, Southern Ward councillor Fleur Fitzsimons has called on the council's chief executive to launch a "detailed and wide-ranging inquiry" into the operation of Wellington Water and its relationship with the council.

"Residents deserve better than the defeatist excuses that have been coming out about our city's infrastructure. Our call for a wide-ranging inquiry is about ensuring that we all know the extent of the problems, how they came about, and how much investment is required to fix the problems", she said

The notice of motion has been seconded by councillor Jill Day.

"Water is a taonga for Māori and the Council and Wellington Water must comply with Te Tiriti o Waitangi in the delivery and maintenance services for water in our city, this inquiry will ask important questions to ensure this happens. I am asking the CEO to ensure that mana whenua are actively involved in the inquiry," Day said

Eight councillors have signed the notice of motion so far, which will be tabled at the council's Strategy and Policy Committee.
