WaterNSW confirmed the work was completed late in 2020, which saw 3.8km of post-tensioned 91 and 65 strand cable anchors installed in the concrete section of the dam wall.

A WaterNSW spokesperson said the important upgrade would "ensure the dam continues to comply to modern safety standards for extreme floods and earthquakes".

"The works required over 170,000 man hours and saw $4 million directly spent in the local community, a fantastic outcome for our customers and the community," the spokesperson said.

This dollar amount includes engineering services (mechanical/electrical), metal work, concrete supplies, light vehicle maintenance, waste management, crane hire, pumps and associated equipment, lifting and mechanical equipment, accommodation, and labour hire.

The type of strand cable anchors used on this project is the highest capacity to have been installed worldwide to date.

Keepit Dam is now the fifth dam in Australia, and the first dam in NSW, to have these cables installed.

The project also included the installation and stressing of the shortest anchors in the world, enhancing industry best practice in the design, installation and commissioning of short anchors in a difficult configuration.

The $146 million WaterNSW project was funded by the NSW Government.

SRG carried out the works.
