Wellington Mayor Tory Whanau wants Government help to fund the city's water do-over

The Council is doing a finances workshop this week.

Wellington Water is asking it for 2.5 billion dollars over 10 years, to fix its leaky pipes - which spill about 40 percent of the city's treated water.

Whanau says they're proposing meters to see where water's going - and also need to spend more.

She says they are not in any financial position to provide investment in the billions, claiming it would need Government support to do that.
