Water engineering

Arup's multifaceted design and engineering skills shape a full spectrum of water solutions.

We see water in context. From delivering water infrastructure to advising on natural catchments, we consider commercial, economic, environmental and social implications.

Arup’s global reach and keen insight into the entire water cycle, and our practical experience in contrasting climates and conditions, brings oversight to our work in water – including infrastructure design and engineering, asset management, flood mitigation, sustainable water management, water strategies and research.

All-round thinking is the product of our specialist engineers, project managersmanagement consultants and environmental and water scientists working seamlessly together – and in partnership with clients.

Future-fit systems

The challenges ahead are considerable. With population growth and climate change risk, the design and management of water infrastructure is becoming more complex.

With oversight, we can better look ahead, whether helping manufacturers such as Diageo secure their future water supply or advising environment agencies on river maintenance and flood protection. Arup’s foresight helps water operators, such as Yorkshire Water and Manila Water, adapt to changes in supply, demand and regulation by bringing greater flexibility and efficiency to their assets and operations.

A look at Arup's work across the entire water cycle.

Balanced solutions

Through our wide-ranging work, we’ve come to appreciate the needs of all water stakeholders regardless of the scale of project. At any one time, we may be designing sewerage infrastructure for 5m Hong Kong residents while elsewhere we are rethinking fish passes to allow fish to safely migrate past obstructions such as weirs.

So when it comes to multifaceted projects – such as the Vistula River Dam, a key Polish reservoir at risk of failure in a protected habitat – Arup brings a truly balanced approach to sustainable water management.

A fresh approach

Complex challenges require original but carefully considered solutions.

Broken Hill, a remote Australian mining town, was facing the high costs of freighting in water when natural sources became inadequate. Arup instead proposed a reverse osmosis desalination plant for Broken Hill, which uses less energy than traditional distillation methods, and proved the town’s most cost-effective option.

Arup pursues novel ideas wherever they can improve water and resource management, such as wastewater treatment facilities that convert sewage sludge to energy.

    Your best solution to date?

    As Project Director I was responsible for the team that initially developed a water reuse strategy for Melbourne Sports Precinct. As a result of the recommendations in Arup’s strategy we were then engaged by multiple clients to deliver the MCG Water Recycling Scheme (as Owner’s Engineer) and Melbourne Park Stormwater Harvesting Schemes (as Detailed Designer). These schemes are two of the most high profile water reuse schemes in Victoria and Australia and have helped the industry to understand how solutions can be successfully delivered to reduce water use and secure supply for high profile sports precincts.

    Why is it significant?

    Melbourne Cricket Club and Melbourne Olympic Park Trust were two of the top 100 water users in Melbourne. This project helped save 150 million litres of potable water per year and also helped raise the profile of water reuse and public awareness of this issue in Australia. The project has won numerous awards. The solutions adopted for this scheme were used to inform the Water Recycling Scheme for the London Olympics. This is another high profile project that has the largest non-potable water network in Europe.

    Your particular skill?

    Ability to engage with clients, understand their problem and develop solutions that are technically innovative and focus on saving clients time and money. Strong technical knowledge of challenges in the water sector and ability to bring together multi-disciplinary teams to develop innovative solutions. Importantly my strength is then to ensure that the solutions developed are clearly articulated in a manner that clients can understand.


    I am passionate about the water industry and helping clients solve complex problems with innovative solutions. I enjoy working in an area of engineering which makes a real and tangible impact to people’s quality of life – both in developing and developed countries.

    Why Arup?

    Arup is an organisation which provides staff with the freedom and environment to excel. I have had the opportunity to work in over 15 countries with international experts developing first of a kind solutions that make a real difference.
