Dams
Dams require understanding and control of water.
Water
Powerful network of water skills and experience.
We offer a broad range of services covering feasibility studies, planning, design, project management, construction and asset management services as well as operational optimisation. Our people use selective research, perform pilot trials, fine-tune existing systems and transfer technologies from other industries to improve quality and manage asset costs.
Ageing infrastructure, growing populations, and threatened water supplies. These are some of the challenges water resource managers must navigate every day. Under constantly changing conditions, we understand the pressure you face in delivering and securing your community’s most critical resource ― water.

Water that supports communities, economies and the environment
Across the world, water providers are facing growing pressure from ageing infrastructure, climate volatility, tighter regulation and rising community expectations. Responding to these challenges takes more than technical excellence alone. It calls for clear strategy, smart investment decisions and the ability to deliver change while keeping essential services running.
For more than 90 years, we have partnered with water organisations to navigate complex challenges across water, energy and communities. Our teams bring together deep engineering expertise and strong business advisory capability, helping clients make informed, sustainable decisions and turn ambition into practical, deliverable outcomes.
Integrated water expertise, from strategy to delivery
We support clients across the full water lifecycle – from early-stage advisory and feasibility through to planning, design, delivery and ongoing optimisation. Our work spans water collection and distribution, wastewater treatment, integrated water management, impact assessment, network modelling and design, dam engineering, hydrogeology and maritime and coastal environments.
Alongside this technical depth, our Business Advisory teams help water organisations navigate complexity by shaping investment strategies, strengthening asset management, improving operational performance and supporting organisational change.
Supporting Aotearoa New Zealand through change
In Aotearoa New Zealand, global water challenges are converging closer to home. Through Local Water Done Well, councils and water organisations are navigating significant change while continuing to provide safe, reliable drinking water, manage wastewater and respond to flood and drought risk.
The decisions being made now will shape communities, waterways and investment outcomes for decades to come.
Our New Zealand water teams bring strong local knowledge, long-standing relationships and a clear understanding of the day-to-day realities facing councils and water providers. Backed by our APAC and global water network and integrated Business Advisory capability, we support clients through periods of transformation – aligning strategy, planning, asset management, digital insight and operational optimisation.
The result is practical, grounded support that helps deliver resilient water services, healthier environments and confident decision-making for communities today and into the future.
