Giant pipe arrives on the Gold Coast

A $70 million plan to revamp the Gold Coast’s waste water network has gone from pipe dream to reality.

A 900m pipe was towed through the Broadwater today to become part of the city’s waste water network.

The pipe will be installed in what has been described as “two of the most complex marine pipeline crossings of their kind in Australia”.

Mayor Tom Tate said the project would increase the capacity of the existing network, which was built in 1990.

“With our population expected to double to 1.2 million by 205, this network will ensure our growing city is well catered for,” he said.

A delicate marine towing operation yesterday played out in the Broadwater involving 13 vessels pulling the polyethylene pipe from The Spit to Waterways Drive, adjacent to the carpark at Pelican Beach.

The pre-assembled 1.2 metre diameter pipe will now be installed under the Nerang River, between Winchester Street in Southport and Main Beach’s Waterways Drive.

The operation will continue tomorrow as it is pulled through below the river bed without disturbing the ecosystem, a process expected to take around 17 hours.

The second marine crossing will be under the Broadwater runs from Biggera Waters’ Quota Park to South Stradbroke Island and involves excavating a shaft at each end and then lowering the pipes in separate segments as they are jacked progressively across the Broadwater.

Several pieces of council’s existing waste water network are being upgraded as part of the project, including pump stations, release points at the Seaway and pipelines on South Stradbroke Island.
