Water is essential to life, and this critical resource needs to be effectively managed to meet the needs of multiple stakeholders and the natural environment.
Significant threats to water security and competing demands include extreme weather events, population growth, aging assets, increasing water recycling, and tighter environmental standards. Water is also a resource that plays a role in the transition to a low-carbon energy future.
That’s why long-term planning is critical to proactively address water scarcity issues and provide resilience in the face of population growth and climate change.
The response to these challenges increasingly forms part of a systems thinking approach, which can be delivered through careful blending of nature-based and traditionally engineered solutions. And by further integrating digital technologies for prediction and optimized system operations, we can better understand river catchment behaviors and the impacts of droughts and flooding.
We have more than a century of water management experience and have played leading roles in many of the world’s largest and most transformative water supply, wastewater, irrigation, drainage, and flood protection projects.
We offer:
Sustainable development
We help water utilities, local and national governments, regulators, industrial customers, and community stakeholders to plan the sustainable management of water resources.
Futureproofing infrastructure and services
We are experts in strategic asset management and in extending the life of existing assets both above and below ground. Our teams are pioneers in reducing the cost and embodied and operational carbon of infrastructure, and in advancing resilience. Our solutions are augmented by leading-edge use of our digital technologies and tools, to maximize value for you, your customers, and wider society.
Systems thinking
Our solutions consider interconnections and dependencies, causes and effects across the natural and built environments. We take a holistic multistakeholder approach to deliver social and environmental benefits at scale.
Environmental management and nature-based solutions
Management of the water environment offers major opportunities for nature-based solutions, particularly in upstream catchment adaptation for flood control and sustainable treatment of recycled wastewater.
Project excellence
Our multidisciplinary breadth enables us to identify and resolve potential challenges — and to realize opportunities — across asset lifecycles. We can help you set strategy, build business cases, secure investment, plan, design, apply transformative technologies, and realize operational efficiencies — achieving excellent project outcomes.
Owners, regulators, and operators need to ensure water infrastructure is adaptable to climate change, emerging contaminants of concern, and the demands of other stakeholders — with affordability in mind.
Meanwhile, wastewater treatment and recycling, energy, and resource recovery must be sustainable to meet stricter environmental standards and minimize climate change impacts. With deep technical expertise from across our global network, we understand these complex challenges.

Global market leader, water
Over the past two decades, cities have embraced new solutions in surface flood management that deliver environmental and social value alongside flood mitigation.
Civil engineer Sally Russell combines her industry expertise and people leadership capabilities as she takes on the role of leading Mott MacDonald’s water and environment business.
With ever-changing and increasingly complex contractual model interfaces, proper understanding and allocation of the responsibility for construction impact assessments, risks, and instrumentation and monitoring is essential.
Carbon Crunch 2025 Auckland brought together sustainability leaders across water, transport, and energy, highlighting the infrastructure and organisational resilience and purpose driving Aotearoa New Zealand’s climate transition.
Late mobilisation remains one of the most consistent drivers of cost, risk and tension in PFI handback, explains Mott MacDonald commercial director Katherine Jackson.
As the first wave of UK PFI contracts approaches expiry, handback is proving to be far more than a contractual milestone. It is where years of decisions, assumptions and asset performance are tested - often all at once.
Pre-construction activities have started on the Ohio River Tunnel (ORT) project in Allegheny County, Pennsylvania, following the award of the over $1 billion construction contract to Brayman-Lane JV.
Mott MacDonald has secured a leading role on Scotland Excel’s £160M national framework, supporting local authorities across Scotland with sustainable infrastructure and engineering services.
The partnership will enable Mott MacDonald and Leed to offer a wholly integrated design and construction team, with a particular focus on the provision and remediation of water infrastructure assets.
National Highways Environment Sustainability Strategy & Standards Group has awarded the Road Period 3 (RP3) Water Quality Plan Technical Partner Support phases to Mott MacDonald, WSP, Ramboll, Arup and AECOM.
Scott brings more than 25 years’ experience across water, environment, transport and buildings for government and private sector clients.
Auckland Council appointed us to redesign Safeswim as a predictive, data-led programme that provides real-time information on water quality and publish health risk at Auckland’s beaches.
The Ohio River Tunnel is the first of three combined sewer overflow (CSO) tunnels at the core of ALCOSAN’s Clean Water Plan.
The vision for the Milldale Infrastructure Projects began in 2016 as part of Auckland Council's strategic plan to enable growth in the area west of State Highway 1 (SH1) near Wainui.
JN Bentley, Mott MacDonald Bentley (MMB) and JBA Bentley provide services in the water sector and other UK engineering and construction markets. Working in close collaboration with our clients and supply chain, we deliver projects all the way from feasibility through to construction, commissioning, and handover - with a focus on providing great outcomes.
