Stantec, GHD to deliver concept design for Warragamba Dam raise

19 March 2018

A joint venture of Stantec and GHD has been awarded a $14.5 million design services contract by WaterNSW for the Warragamba Dam Raise west of Sydney in New South Wales, Australia.

The Warragamba Dam Raising Concept Design will look to increase the height of the existing dam, allowing it to be used for flood mitigation purposes that will benefit the downstream community. Since 1960, twenty moderate to major significant floods have impacted the Hawkesbury-Nepean Valley.

“We are proud to work with WaterNSW on this exciting project and have assembled a technical team who bring experience from dam raise projects completed around the world,” said Ashok Sukumaran, Stantec’s General Manager for Water in Australia. “This mix of local and international expertise will deliver a complex design that meets safety standards and optimizes the dam configuration for the purposes of flood mitigation.”

The services provided by the partnership of Stantec and GHD will include developing a cost-effective and safe design for raising Warragamba Dam, while addressing and mitigating any project impacts. Design services are expected to be completed by early 2019.
