Pipes capable of carrying 3000 litres of water a second are now being installed under the girders of the second Manukau Harbour bridge.

The 1km “under the bridge” section is part of Watercare Services’ $245 million Hunua 4 pipeline project.

Construction on the pipeline won’t start until 2012 but the bridge section is being done now so residents won’t be disrupted twice.

The pipeline will run for about 30km – from Redoubt North Reservoir to Murphys Rd then under Thomas, Boundary, Reagan and Puhinui roads and across Pukaki Creek to Mangere.

From there it will pass under Kirkbride, Mountain and Coronation roads, under the new harbour bridge to Onehunga and on to Epsom.

Hunua 4 project manager Andy Spittal says the new pipeline is being installed to cater for future demand and to secure the water supply, particularly in Manukau city and the airport precinct.
