Wellington City Council has applied for extra funding to assess the state of the city's pipe network after two burst pipes within three days in the capital.
On Thursday a burst watermain flooded parts of Aro St, causing residents to lay down sandbags to redirect water from their garages.
Days earlier a burst wastewater pipe in the central city sent sewage on to the street, with residents urged not to flush the toilet unless "essential" while authorities scrambled to isolate the leak.
The pipe, on the corner of Victoria and Mercer St, was built in the early 1900s.
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.
