AECOM Secures SE Queensland Dam Security Contract

BRISBANE (March, 2025)—AECOM, the trusted global infrastructure leader, today announced its appointment as the dams engineering services provider for Seqwater's Dam Improvement Program and other dam infrastructure projects planned to be completed by Seqwater now and into the future. This appointment continues AECOM's decades-long partnership with South East Queensland's bulk water supply authority in one of Australia's fastest-growing regions.

AECOM will progress major works including the next tranche of upgrades on the region's gated dams – Wivenhoe, Somerset and North Pine. This includes supporting Seqwater on key technical planning and design activities to finalise the Detailed Business Case (DBC) for the Somerset Dam Improvement Project. AECOM will also support on the DBC for the North Pine Dam Improvement Project and the Options Analysis (OA) for the Wivenhoe Dam upgrade.

"Together with Seqwater, AECOM is committed to ensuring South East Queensland's dams can continue to withstand extreme weather events," said Beverley Stinson, chief executive of AECOM's global Water business. "Our teams are committed to ensuring the ongoing safety, resilience, and reliability of Queensland's water supply systems using the full depth of our global capabilities, and we look forward to supporting Seqwater's vision for a sustainable future and ensuring the communities we serve have access to clean, safe drinking water for generations to come."

"We are excited to continue our trusted partnership with Seqwater, a leader in delivering sustainable and innovative water solutions for South East Queensland," said Mark McManamny, AECOM's chief executive of the Australia and New Zealand region. "Our long-standing relationship with Seqwater has been pivotal in advancing other critical infrastructure projects for the bulk water supply authority, including for Hinze Dam and the Lake Macdonald Dam Improvement Project."

Enabling works are expected to commence on-site at Somerset Dam in 2025 as part of the first stage of its upgrade. Staged strengthening works are also expected to commence at North Pine Dam this year to deliver enhanced safety benefits ahead of the major upgrade, and geotechnical investigations to inform the Wivenhoe Dam OA concluded late 2024.

Seqwater is South East Queensland, Australia's bulk water supplier responsible for delivering safe, secure bulk water supply to more than 3.8 million people in South East Queensland. Seqwater owns and operates 26 dams and will upgrade its three largest, dams to achieve modern engineering and safety standards. These dams provide water security and flood mitigation for the South East Queensland region.
