Mott MacDonald Bentley's (MMB) Faringdon storage solutions scheme, delivered for Thames Water secured the 'UK Project with a Geotechnical Value of between £500K and £1M' Award at the annual Ground Engineering Awards. Delivered on behalf of Thames Water, Mott MacDonald Bentley’s Faringdon storage solutions scheme forms part of a wider programme to improve stormwater management and support future WINEP and Environment Agency requirements. The project involved the design and build of a new combined sewer overflow (CSO) and screening chamber, storm storage provision, a return pump station, and associated infrastructure. However, the original concept centred on a large open-cut excavation, which presented significant challenges due to complex ground conditions, environmental constraints and limited working space. Through early geotechnical assessment and detailed analysis, MMB identified substantial risks linked to slope stability, groundwater and proximity to protected woodland. In response, the team led a full design review, working closely with Thames Water and H&B Tunnelling to develop a more robust and sustainable solution. The adopted shaft solution significantly reduced the excavation footprint, minimised environmental impact and removed the need for complex temporary works, ultimately delivering a safer, more efficient and more buildable scheme. The judges highlighted the project’s “understanding of ground conditions and associated geotechnical risks”, while the use of a “three-dimensional ground model gave the team the foundation needed to challenge the initial design and deliver a more elegant and efficient engineering outcome." Dr Mark Edmondson, MMB’s regional discipline lead for geotechnics and ground engineering, added: “It is rewarding to see such positive feedback and clearly demonstrates the true value our integrated technical disciplines bring to delivering successful outcomes for our clients.” Commenting on the award win, Dan Buxton, director, said: “We’re really pleased to see the Faringdon scheme recognised at this year’s Ground Engineering Awards. It’s a great example of how early geotechnical insight and collaboration can drive better, safer and more sustainable outcomes for our clients.” MMB was well represented across the awards, with the Cleobury Mortimer STW AMP7 replacements works, delivered in partnership with Severn Trent being highly commended by the judges in the ‘UK Project with a Geotechnical Value of between £1M and £3M category’. Whilst the project team for Springwell Enhancements, delivered in collaboration with Northumbrian Water, was also shortlisted in the ‘UK Project with a Geotechnical Value of between £3M and £10M' category. __________________________________________________________________________________ Find out more about our award-winning projects in our latest annual review.

The Mott MacDonald Bentley (MMB) team behind the Witches Oak Raw Water Abstraction and Wetlands scheme took home the Climate Mitigation and Adaptation Award at the annual ICE East Midlands Merit Awards, while design lead Tanya Donkin was named Regional STEM Ambassador of the Year. On behalf of Severn Trent, Mott MacDonald Bentley (MMB) has delivered a ground-breaking scheme at Witches Oak Raw Water Abstraction and Wetlands, bringing an abandoned water resource back into use to improve the resilience of drinking water supplies during future droughts. At a series of former gravel pit lakes near the River Trent, the project is increasing raw water supply through the recommissioning of infrastructure alongside innovative, low-carbon, nature-based solutions. MMB has delivered floating treatment wetlands across the lakes to act as the first stage of treatment, using natural biological processes to remove pollutants such as ammonia and suspended solids and reduce reliance on energy-intensive methods. Mimicking self-sustaining riparian habitats (those next to rivers or streams), the wetlands provide a resilient, low-maintenance solution while supporting biodiversity and habitat creation. As the first application of its kind at scale in the UK, Witches Oak demonstrates how nature-based solutions can be integrated into operational water infrastructure, showcasing how a low-carbon solution can directly improve water quality. Through close collaboration and community engagement, the scheme provides a sustainable, replicable model for enhancing ecosystems, improving resilience, and reducing reliance on traditional treatment methods. Commenting on the award, Declan Mawson, director said: “We’re incredibly proud to see the Witches Oak scheme recognised with this award. It’s a powerful demonstration of the vital role nature-based solutions can play in the future of water infrastructure – using innovative, low-carbon approaches to improve water quality, strengthen resilience, and enhance the natural environment. The project is a real testament to the collaboration and expertise across the Severn Trent and MMB team.” Alongside project success, MMB design lead Tanya Donkin was recognised as Regional STEM Ambassador of the Year for her outstanding commitment to inspiring the next generation of engineers. Through her extensive involvement in STEM outreach, from leading work experience programmes and supporting schools to engaging with communities and championing industry initiatives, she has made a significant impact across the region. Reflecting on her award, she said: “I’ve always been passionate about civil engineering, which is why I enjoy taking part in STEM and work experience events to inspire others. It’s such a varied field, but at its core it’s about solving problems, making a difference, and benefiting society.” Well done to all the winners and finalists. __________________________________________________________________________________ Read more about our nature-based solution at Witches Oak Green Recovery

Mott MacDonald's "Pushing the Boundaries" page showcases AI and data analytics use in innovative tech development and digital twin case studies Back Next About us Introducing JN Bentley Vision and values Publications Virtual reality Health and safety Enhancing the environment We must deliver quality solutions in a cost and efficient way. Doing so ensures we add value for our clients and continue to thrive as an organisation. How do we achieve this? Through our Quality, Cost & Efficiency Strategy. Quality, cost and efficiency OUR APPROACH Augmented reality This is an overview of digital in JN Bentley, including our investment in digital delivery and our company digital transformation and how it is embedded in everything we do. Digital delivery OUR APPROACH Pushing the boundaries As an employee-owned company, we make our own decisions about where to invest our money. One of these areas of investment is developing ideas and discovering new technology and digital tools to keep us at the forefront of the industry. As part of the Mott MacDonald Group, we collaborate with teams across the world and partner with organisations who recognise us as industry leaders in this space. Artificial Intelligence (AI) – We use AI to check our risk assessments and method statements, drawing from our Operational Safety Standards to give instant, relevant and comprehensive documents which increases our efficiency, productivity, and performance. Data analytics – We develop powerful business intelligence dashboards to provide the insight our teams need to make better decisions. We are also working with partners who use predictive analytics to provide advance knowledge of safety performance based on previous and real-time data fed into an AI powered model. This allows us to deliver proactive support to our projects that need it most. Case study: Digital twins During the design, build and commissioning of a £37m sludge treatment plant at Five Fords in Wales, we identified that the sludge treatment process required complex conditions and a controlled environment to operate successfully. We adopted a digital twin approach to give us and our client more certainty during the commissioning stage to mitigate risk and shorten the lengthy programme. The development of the twin was driven by two key questions: 1. What if we knew how the plant was going to perform in the future? and, 2. What if we could virtually simulate operating conditions before making decisions? A platform to capture, process and visualise the data was also required, as well as a calibrated, real-time model to provide analytics. Our digital twin platform, Moata , processes billions of data points daily and can integrate with multiple software packages and machine learning modules, making it a powerful digital twin platform built for scale. To dynamically model the complex biological process, the industry-leading wastewater simulation software Biowin was used. Biowin, developed by EnviroSim, was integrated with Moata to provide real-time insight into plant operation. The digital twin solution helps to optimise performance, reduce energy use and cut chemical consumption. The Five Fords digital twin has allowed the team to move from reactive to proactive decision-making, and it is creating a real step-change in how we manage our assets. This is one small part of creating a wider digital twin for all water and wastewater assets. It involves building an ecosystem of supply, distribution and treatment assets and integrating catchment-wide aspects of the water cycle, such as rainfall predictions. This will only occur through collaboration and strategic partnerships, ensuring we are using the best expertise on a global level.
