Government confirmed yesterday that it had awarded an $11.2 million contract to local company Land Holdings Ltd to redo substandard pipework.
The replacement of 17km of botched pipeline – a third of those laid by the China Civil Engineering Construction company – is expected to take eight months to complete.
Work is to start next month, first around Nikao/Arorangi, followed by Muri and Avana. The roads through Avana and Muri have already besn dug up twice this year.
Secretary for Finance Garth Henderson said independent engineering assessments indicated a need to undertake further work on the most critical sections of the network, where resilience was particularly important.
“We are pleased to be awarding this work to Landholdings a local company, which has in-depth knowledge of the water supply network and an excellent track record.”
Land Holdings had successfully completed an earlier contract to connect the water supply sub-main from private and commercial properties to the new ring mains around Rarotonga.
Henderson explained the Muri/Avana section was a priority because a single pipe link provided water from Avana intake to the south and west.
The Nikao/Arorangi section was important because the ring main on the inner road behind the airport was a single critical link from Avatiu intake to the Nikao and Arorangi areas.
This work will provide a 100-year design life for these critical sectors of the network, he said.
“The Government will implement a long term operational and maintenance strategy to safeguard network performance and provide resilience to any future failure and loss of supply.”
Meanwhile, Te Mato Vai confirmed Te Mato Vai Stage two project, completing the engineering work for the new freshwater supply, would again be delivered by McConnell Dowell.
