As part of maintaining the supply of high-quality drinking water to East Gippsland Water customers, works are being undertaken to replace the 88ML basin liner and cover at the Wy Yung water storage facility.
This $6 million project involves the replacement and/or repair of any drainage pumps, floats, access hatches, underdrainage system, stabilisation of the clay liner and the installation of a new geomembrane liner and floating cover.
“The 88ML Wy Yung basin is an
important piece of infrastructure that supplies our customers in Bairnsdale
and the surrounding areas with
high-quality drinking water,” East Gippsland Water executive manager sustainability
and infrastructure, Neville Pearce,
said.
“We detected an issue with the polypropylene liner that has compromised its integrity, resulting in a leak into the underdrainage pipe. The pipe has been isolated to reduce internal erosion.
“Over the past few months, we have been undertaking preparatory works to prepare the basin for the liner replacement
works. This has involved testing the
36ML concrete water storage tank that is being used as the main water supply system while the
works occur and drawing down the water in the basin to our customers and
diverting water into our Sarsfield storage tanks.
“Around 12ML of water that was unable to be pumped has been drained via the eastern scour point along Eastwood Road into Clifton Creek. This is potable water with no traces of chlorine.
“We are delighted with the progress and works are due to commence mid-March 2024.”
The contract has been awarded to Fabtech, a company specialising in the
design and installation of geomembrane
liners and covers. The works will take
around six months to complete, weather dependent.
