Round-the-clock project

LETTERS are being sent to numerous Yamba residents to keep them informed of progress on the next stage of the Yamba sewerage augmentation scheme, which is due to get underway next year.

The work involves the construction of a pipeline from the Yamba sewerage treatment plant, which is currently being upgraded into and then under the Clarence River, ultimately reaching an ebb-tide release point adjacent to the Iluka sewerage scheme's release point.

Clarence Valley Council works and civil director, Troy Anderson, said the council was writing to selected residents to let them know how they might be affected during the construction phase.

Recycled water from the plant will be treated to tertiary standard and most will be used on sporting fields or otherwise recycled, but in periods of high rainfall any excess will be released in the river on an outgoing (ebb) tide.

Mr Anderson said building the ebb-tide release point would require the construction of a pipeline from the plant to the river and underground drilling (horizontal direct drilling) for a pipeline to near the centre of the river.

"Technical experts have told us there is a risk of bore failure if work is stopped overnight, so it will be a 24-hour a day operation for about two months," he said.

"We expect work to run between July and September 2015 and for the drilling equipment to be set up on vacant lots next to the Pegasus Motel.

"Residents in some areas will be affected by construction noise, light and increased traffic, but we will make every effort to ensure disruption is kept to a minimum.

"The successful construction contractor will be required to meet pre-set noise levels and to undertake noise monitoring at affected properties. If they fail to meet the noise guidelines, they will be required to undertake remedial action."

"Accordingly, council has prepared a supplementary Review of Environmental Factors, which will be on display and open for comment until September 1," he said.

"A printed copy of the REF is available for viewing at the Treelands Drive Community Centre in Yamba, at the council offices in River Street, Maclean, and can be downloaded at clarence.nsw.gov.au/yambaref or clarenceconversations.com.au

"If people have particular concerns they don't think have been adequately addressed or are unclear about some of the information, they should contact council's water cycle administration team on 6645 0000."
