Wellington Water is asking Wellington City Council for $2.5 billion over the next ten years to achieve the best outcomes for water infrastructure in the city.
Chief executive Tonia Haskell says it's the maximum they are asking from the council, which would work out to about $250 million a year, but the spending would increase later in the decade.
Haskell says even with enough investment, the capital won't start seeing noticeable improvements to pipe issues for the next five years.
She says the agency really needs $1 billion each year from the region, to solve the water infrastructure crisis.
Haskell spoke to Corin Dann.
