Projects

DALLAS (April 8, 2025) — AECOM (NYSE: ACM), the trusted global infrastructure leader, today announced it has been selected as a Design Development Partner for Sydney Water, Australia’s largest water utility. In its role, the Company will support Sydney Water to deliver a transformative capital investment program over the next decade. This initiative aims to support Sydney’s rapid growth, enhance climate resilience, and renew aging infrastructure to ensure a sustainable and reliable water future.

“As the world’s top water design firm, we couldn’t be prouder to partner with Sydney Water on one of Australia’s largest and most critical water infrastructure capital programs to date,” said Beverley Stinson, chief executive of AECOM’s global Water business. “This contract builds on numerous, recent major Water wins across our business, and we look forward to applying learnings on some of the world’s most complex water programs to support a more reliable and climate-resilient water supply for Greater Sydney.”

Sydney Water’s capital investment program is an adaptive plan that captures the utility’s key infrastructure and operational decisions to 2050, in alignment with the New South Wales Government’s vision for Greater Sydney. It seeks to address the impacts of rapid population growth, ageing assets and environmental pressures while supporting economic development and community well-being.

As a Design Development Partner, AECOM will provide high-quality engineering design services to develop preferred options and concept designs and derisk projects in cost and time across a full range of projects and asset classes, including pipes, pumps, reservoirs, treatment plants, and facilities.

“We are excited to continue our partnership with Sydney Water as they drive innovation and sustainability in the face of Greater Sydney’s rapid growth,” said Mark McManamny, chief executive of AECOM’s Australia and New Zealand region. “Together with AECOM’s global water specialists, our Sydney team will apply deep local expertise and a shared commitment to sustainable solutions, ensuring we continue to deliver lasting benefits to both the environment and the people of Sydney.”

Sydney Water provides safe, high-quality drinking water to 5.3 million customers every day across Greater Sydney, including the Blue Mountains and the Illawarra.
