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 Bentley recently hosted a Quality, Cost and Efficiency (QC&E) Fortnight, bringing together teams from across the business to share how standard products are improving delivery for clients. The fortnight saw participation from colleagues across the business from support functions to project teams, to share examples of how standard products are already delivering benefits in quality, cost and efficiency. The sessions highlighted a clear, consistent message: when we design once and reuse well, we reduce complexity, improve safety, accelerate delivery and provide better value for our clients. Understanding standard products Standard products are pre-designed solutions that are ready to use across MMB projects and frameworks. They typically include approved drawings and calculations, and for some products, additional resources such as design guidance, installation instructions and programme information. MMB’s unique position in the regulated water market enables the business to bring engineers, procurement professionals, other support teams and the supply chain together to develop a growing library of standard products and embed them across project delivery. Standard products is one of MMB’s QC&E commitments, reflecting the role that standardisation plays in delivering speed, quality and value. With affordability one of the key challenges facing clients, utilising a growing suite of standard products is helping MMB deliver better value – reducing design time and shortening construction sequences to deliver quicker. Standardisation examples MMB’s use of standard products continues to grow. Progress in 2025 included the development of a prefabricated plastic draw pit chamber, alongside a parallel thermoset plastics option for clients who prefer this material. The product has been deployed across multiple clients including Thames Water, Northumbrian Water and Yorkshire Water. With many settlement tanks to deliver throughout AMP8, MMB has developed a product to standardise MMB’s procurement, design, construction and commissioning. The pre-cast concrete Sealwall tank – developed with Naylor Concrete Products – was deployed with the likes of Severn Trent and Dŵr Cymru Welsh Water. MMB’s partnership with Naylor has seen the business obtain sample panels that are being used to train internal teams, ensuring ‘right first-time’ installation on site. This commitment to standardisation improves efficiency, boosts productivity and enhances site safety – helping to deliver better outcomes for both project delivery teams and clients.

The Mott MacDonald Bentley (MMB) project team responsible for delivering the UK's largest integrated constructed wetland (ICW) proudly took home the Centenary Award for projects valued over £5m, at the annual Institution of Civil Engineers (ICE) Yorkshire and Humber Awards. On behalf of Yorkshire Water, and working in partnership with Stantec, the pioneering 'first-of-its-size' scheme at Dearne Reach, Yorkshire, is now a benchmark for delivering low-carbon, nature-based solutions to support stormwater management and deliver water quality improvements. MMB designed and built thirteen adjacent wetland cells - housing over 350,000 plants of 52 different species - engineered to naturally treat effluent to improve 4km of the River Dearne. Using natural processes such as sedimentation, filtration and biological uptake, the ICW removes pollutants including ammonia, biological oxygen demand (BOD) and suspended solids. The solution is a sustainable alternative to traditional concrete infrastructure - which would have entailed 7,000 m³ of storm storage - and is creating many new thriving habitats. As the largest ICW of its kind in the country, Dearne Reach showcases the capability of the UK construction industry to deliver low-carbon, climate-resilient infrastructure at scale. Lessons learned from both design and delivery are already being shared across the industry, helping to drive continuous improvement and innovation in sustainable water management. In doing so, the project not only improves river water quality and biodiversity today but also strengthens the evidence base and confidence needed to accelerate adoption of nature-based solutions nationwide. Commenting on why the project deserved the award, the ICE judges said: "The Dearne Reach scheme is an exemplar for using nature-based solutions to respond to water challenges while delivering enhanced biodiversity and catchment-wide water quality benefits.” The judges were further impressed by the project’s use of digital tools and AI to optimise how the earthworks were managed, congratulating the team for their commitment to excellence every step of the way, from feasibility through to construction. Aerial view of the integrated constructed wetland cells at Dearne Reach Thanks to its innovative, industry-leading and sustainable approach, the project is now a triple award winner. In 2025 the team achieved National Gold at The Green Organisation International Green Apple Environment Awards, and also received the win for 'Going the extra mile' at the Civil Engineering Contractor's Association (CECA) Yorkshire and Humber Awards.
