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

JN Bentley's "Digital Rehearsal" optimizes construction planning with technology, aligning design and programs for enhanced safety and efficiency Back Next About us Introducing JN Bentley Vision and values Publications Repeat business is the recognition that we’re looking for - but it’s nice to pick up an award or two along the way. Awards ABOUT JN Bentley Ltd is part of the global management, engineering and development consultancy Mott MacDonald, offering our clients full feasibility, design and construction services throughout the UK. Who we are ABOUT We integrate inclusion and belonging, professional and personal development, and health and wellbeing into our business culture. People OUR APPROACH Our aim is to reduce water consumption, minimise our waste, and use energy efficiently. Preserving resources OUR APPROACH 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 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 Digital rehearsal Digital rehearsal optimises how we plan the construction phase of our projects. It aligns design with the construction programme and drives collaboration between people and technology, enabling project teams to rehearse the construction sequence at the right time with the right set of people to identify the best sequence in terms of safety, supply-chain, operational site interfaces and temporary works logistics. Designers get a better understanding of buildability and construction teams understand the specification and any client operational constraints. Case study: Hallbank Tunnel Hallbank involved a short shutdown of an aqueduct supplying 2.5 million customers with 570 million litres of water a day. After nearly two years of main works, our client handed the entire site over to us to complete the connections. At its peak, 90 engineers on round-the-clock shifts worked at each connection. We developed a highly detailed 4D model that facilitated collaborative rehearsals with the team and ensured the operation was meticulously planned. The connections were a success, and the site was handed back to our client early. The 4D model maximised efficiency and supported collaboration between the design and construction teams. The model also helped to identify temporary works and process constraints, beyond the realm of 3D clash detection. Case study: Embsay Water Treatment Works During the investigation and tender stage at Embsay, SYNCHRO 4D was used to create a digital rehearsal to better understand sequencing on an extremely tight site. Outputs from the rehearsal led directly to programme updates, saving 10 weeks and over £100,000 in preliminary site costs.

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 Health and safety 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 Preserving resources Our aim is to reduce water consumption, minimise our waste, and use energy efficiently. We’ve supported innovative practices to drive low water commissioning techniques, which can support up to a 95% reduction in commissioning water usage. We follow the waste hierarchy, considering waste and resource management from the outset of project delivery to minimise waste and re-use, recycle and recover as much as possible. Our waste management target is to direct >95% of the waste we generate from landfill. We continue to seek efficiencies in our operations and are seeing benefits from standardised site setups that use cabins with improved EPC ratings; the use of battery storage units on site; and the introduction of Stage V engines in our plant fleet. We actively monitor energy consumption across offices: the majority of electricity used here has been moved to green tariffs with REGO (Renewable Energy Guarantees of Origin) certification. We are also certified against ISO 50001 for Energy Management for the design, construction and commissioning of building and civil, mechanical and electrical projects.
