Quake-damaged pipes in Wellington are leaking around one million litres of water every day.
The system has been in this state since the November 14 Kaikoura earthquake, but authorities have no idea where the quake-damaged pipes are in the network.
Authorities will continue to carry out detection programmes to find the leaks, Wellington Water's latest outlook report states.
Councillor Iona Pannett said meters will be installed throughout the city to try to narrow down where the leaks are.
She's confident the wasted water will be treated as a pressing matter.
