Urban populations are growing while climate change means both droughts, as well as sudden intense rainfall events, are on the rise. However, existing urban infrastructure in UK has not caught up with the water management challenges presented by these scenarios. We need to be much smarter about the capture, usage and planned management of water going forward. This is critical to reduce flood risk and to be prepared for periods of drought.   In this episode, New Civil Engineer assistant news editor Rob Hakimian is joined by two guests to discuss the topic - Charlotte Markey, who is green urbanisation innovation manager at Polypipe, and John Griffiths, who is national account manager at environmental data management solutions company Kisters..   In conversation with Rob, Charlotte and John outline the opportunities for upgrading existing infrastructure to blue green infrastructure in the UK, explaining examples including tree pits, rain gardens and blue green roof systems. They also explain the growing importance of data collection – particularly using smart sensors. Both Charlotte and John suggest that this data could be an untapped resource that might be better leveraged with a more strategic “joined up” approach on the part of government, utilities providers and other water management stakeholders. They also talk about on their involvement a recent pilot project in Manchester that saw the installation of a climate and water resilience research roof in the heart of the city. The project is helping to drive understanding of how a combination of construction and data technologies can help mitigate the impacts of climate change and urbanisation. It demonstrates how storing and re-using rainwater can reduce the volume of surface run-off impacting important assets such as sewer networks.  Charlotte and John compare the approach in the UK to elsewhere globally and consider the implications of not changing the approach to surface water management and the role smart data can play in that. Listen now to hear about how blue green infrastructure and smart rainwater management can play an ongoing role in the UK’s climate resilience. The Engineers Collective is proving truly global in reach, with a third of listeners based outside the UK. It is also appealing to an inquisitive, career-builder demographic, with 80% of listeners under 35. Special guests on previous episodes have included Crossrail managing director Mark Wild, HS2 Ltd special advisor Andrew McNaughton and ICE president Ed McCann. All are available for download and all address current and ongoing issues around skills and major project delivery. The Engineers Collective is available via Apple Podcasts, Spotify, A-cast, Stitcher, PodBean and via newcivilengineer.com/podcast The Engineer’s Collective is powered by Seequent, the subsurface software specialists. Around the world, teams are using PLAXIS, OpenGround, Leapfrog Works, and GeoStudio to design, build and operate safe, sustainable, and long-lasting infrastructure, from roads to rail, bridges to tunnels, and buildings, dams and levees.
