Wellington City Mayor Andy Foster said the council had applied for extra funding from central government, for what was known as a "conditioning assessment".
"That will help build a much better picture of what the state of the network is and where we need to target for renewal."
"The first concern is making sure we understand the state of it – that's why we have looked to the extra funding for the conditioning assessment."
"And then that will be followed up by extra funding to actually do the renewal work."
There was no timeline yet for when the network would be assessed, he said, with the council meeting with Wellington Water next week.
Yesterday's burst water pipe caused water to gush from under the road at 195 Aro St, with water and rocks sprayed across the street.
Wellington Water reported crews were on site by 4.30pm and had isolated the broken main with no loss of service to customers within the catchment area.
