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.
