A Sunshine Coast contractor has been awarded the contract for the $24 million Ewen Maddock Dam upgrade.
Hall Contracting will begin work on the dam in late March 2020.
Natural Resources Minister, Dr Anthony Lynham, said the project would bring the dam in line with modern engineering design standards and improve the existing beach and swimming area.
“Across the state, our publicly-owned water infrastructure has to meet modern engineering and safety standards,” Mr Lynham said.
“This project is part of an ongoing dam improvement program that ensures all of our dams perform safely well into the future.
“This is a great outcome with a local contractor being awarded the work for the first stage.’’
Construction on the 18-month first stage is planned to begin at the end of March 2020 and will involve raising and strengthening the existing embankment walls with significant improvements to the recreation area.
The dam’s water level will have to be lowered to about 60 per cent of its full supply to allow the works to proceed.
Seqwater Chief Executive Officer, Neil Brennan, said the designated swimming and beach area, as well as Maddock Park, would need to close for up to 18 months during the first stage.
“We understand that Ewen Maddock Dam is a very popular recreation destination and apologise for any inconvenience to the local community,” Mr Brennan said.
“Seqwater has staged construction to reduce the amount of time water levels have to be lowered and to minimise the closure of the lake.
“The walking and mountain bike trails will still be available at the Ornamental Wetlands area, off Steve Irwin Way on the opposite side of the lake.
“We aim to re-open for recreation as soon as practical once the 18-month first stage is complete.”
The second stage will involve strengthening the existing spillway and will be subject to a separate tender process. The timing of stage two works is expected to be finalised by the end of 2020.
