The $100 million-dollar project will see the dam become fully compliant with NSW Dams Safety Committee standards for extreme weather events and seismic activity. SRG is undertaking the works.

Progress to date includes the completion of demolition and concrete surface preparation works for the dam monolith blocks (concrete blocks that form the dam wall sections), and drilling for cable anchors, according to a WaterNSW spokesperson.

In addition, more than 2.5km of post-tensioning anchor cables have been installed on the dam crest and the overflow section of the dam, and more than 35 tonnes of reinforcement bars have been installed for the spillway pier bearing pad.

Drilling of vertical holes on the right-hand-side and left-hand-side abutments and on the overflow section for cable anchors through the existing concrete into the foundation has also been completed.

A WaterNSW spokesperson said workers will now start drilling inclined holes for cable anchors through the existing concrete of the spillway piers. Installing, stressing and testing of cable anchors will continue over the next 6-9 months. The project is expected to be completed this year.

The engagement of local sub-contractors and suppliers is estimated to be in excess of $2 million.

The WaterNSW project is funded by the NSW Government, with public access to the wall cut-off until further notice.
