Two sewage mains running underneath the Terrigal Lagoon in the Central Coast region of New South Wales will be rehabilitated as part of the Central Coast Council’s sewage pump station upgrade program to improve operations.
The rehabilitation works will include placing a plastic liner insider each of the steel pipes and the removal of the temporary polyethylene pipe that was installed in July 2013.
The two mains cross below the bed of the Lagoon in an east west direction, from the sewage pump station on Bundara Avenue, Wamberal, to the intersection of Beaufort Road and Ogilvie Street, Terrigal.
Council’s Construction Delivery Coordinator, Mark Losurdo, said the works will ensure the pump stations and rising mains will continue operating to the highest standard.
“Council is committed to protecting the community, our waterways and the environment against sewage overflows,” Mr Losurdo said.
“In July 2013, a temporary 355mm diameter pipe was installed to replace one of two sewer rising mains that was not functioning to its optimum capacity.
“The temporary pipe will be decommissioned and disposed of, whilst minimising the risk of any environmental impact.
“Construction works will also be undertaken for the rehabilitation of the existing mains, including civil works required for the interconnection at the eastern and western shores of Terrigal Lagoon.”
Construction is expected to commence on 26 September 2016, and is due to be completed in November 2016.
