Thames Water Read more Water, telecoms and energy gallery Building sustainability into everything we do There has never been a more critical time to consider the impact of infrastructure on the environment. Wrekin, along with the wider civil engineering industry, takes this responsibility extremely seriously. We are committed to reducing our environmental footprint through innovation, quality design and responsible manufacturing. From developing products that increase whole-life performance to recycling materials and reducing waste, every improvement helps us move towards a more sustainable future. As the effects of climate change become more apparent, the UK is facing increased rainfall intensity and more frequent flash flooding. These conditions put additional strain on underground networks and road infrastructure. Wrekin’s Unite range has been developed to address these challenges. Our retrofittable seal plates provide an added layer of protection where and when it's needed, preventing water ingress and odour escape while maintaining the performance and integrity of chambers during extreme weather events. Our sustainability focus extends beyond product performance to the entire lifecycle. As highlighted in our pothole whitepaper, correctly specified and installed ironwork dramatically reduces the likelihood of early-life failure and reinstatement defects. This “right first time” approach helps lower long-term maintenance costs while driving down whole-life carbon emissions, a benefit independently verified through our BRE-verified Environmental Product Declarations (EPDs). Data collection to analyse performance is critical to overcoming some of challenges faced. Our ID bolt location, has been designed to accommodate antennae and data-capturing equipment for monitoring, chamber logging and network management. This feature supports the integration of smart technologies, enabling operators to gather real-time performance data and respond proactively to environmental events. By combining intelligent engineering with practical innovation, Wrekin is helping the industry prepare for a changing climate, delivering solutions that protect infrastructure, extend service life and contribute to a more resilient, low-carbon future.
