Wastewater treatment is an overlooked lifesaver. While the medical advances of the last 100 years—penicillin, chemotherapy, and, more recently, mRNA vaccines—have transformed healthcare, keeping our water supplies free from pathogens like cholera and dysentery, has saved many more lives. The systems developed to treat wastewater are so successful that we can afford to flush and forget. But this is infrastructure we must not overlook. Growing populations, increased use by industry, and regulations that get tighter as we learn of new threats to human life and the environment, are putting wastewater treatment facilities under strain. Existing plants are often tucked away on constrained sites, and work as part of a sprawling network of sewage systems that make it extremely difficult for them to be relocated. This is very much the case at Ringsend in Dublin. Here, on a site bounded by other facilities and the sea, the waste produced by millions of Dubliners—and the city’s industry and commerce—must be processed before being discharged into the Liffey Estuary. To update the plant, its owners had considered building a 9km pipe to discharge waste outside of the sensitive areas of the estuary. But a new solution was identified. By implementing a novel form of biological treatment, developed by Haskoning, Egis was able to ensure that the effluent discharged was so clean, it would be safe for wildlife. But installing this would take careful planning and scheduling, in order to complete the work in tight constraints, without any pause in plant operations. Guests Marisa Buyers-Basso, associate director, Haskoning Marcus Fagan, chartered engineer, Egis Partner Egis is a leading global architectural, consulting, engineering, operations and mobility services firm with 22,000 employees across more than 100 countries.

Green-grey engineering combines nature-based solutions with traditional civil engineering. It can be used in flood protection, with mangroves acting as a first line of defense rather than relying wholly on seawalls or earthen berms. As parts of the world face dual threats of flood and drought, the same systems can incorporate drainage and water collection. Unlike traditional civil engineering, nature-based solutions offer a wide range of additional benefits. Mangroves act as fish nurseries feeding local communities and boosting economies. They sequester carbon, helping limit climate change. They provide opportunities for tourism. And they provide significant flood protection, boosting resilience. But there is a need to scale and accelerate funding to address the loss and protection of coastal ecosystems and the true value they represent. A new analytical framework, Net Ecosystem Value, offers a tool to inform this need. Rich geodata insights, analysis and scenario modelling combined with local knowledge and academic research. This environmental and economic accounting demonstrates the true value of investing in these solutions, as well as the cost of doing nothing. By providing more granularity, rather than relying on global assumptions, this supports the development of relevant financial mechanisms such as blue bonds. By taking a whole-of-ecosystem approach, Net Ecosystem Value is able to show the true value of investing in coastal zones as critical infrastructure that accounts for blue carbon, fisheries, resilience, biodiversity, livelihoods, and social and cultural values In this episode, Alpa Bhattacharjee and Rod Braun explain the broad range of benefits these ecosystems offer, and the progress that is being made to incorporate them alongside traditional civil engineering solutions.

The infrastructure sector is adopting AI with enthusiasm. A new whitepaper from Bentley Systems, Pinsent Masons, Turner & Townsend, and Mott Macdonald, The Impact of Artificial Intelligence on the Built Environment, surveyed the sector, and found the 48% of the infrastructure companies they spoke to were trialling AI, or had already implemented it. But only one fifth had a comprehensive AI policy, more than a third had no organisational policy, and 37% had only limited project controls, or none at all. As part of Bentley Systems Year In Infrastructure series of events, Mark Coates hosted a panel discussion on the white paper. Bringing together key members of the infrastructure sector—engineers, contractors, and lawyers—the panel discussed how infrastructure businesses can implement a project management approach to AI implementation. In this episode, Mark Coates joins us to examine some of the risks associated with AI adoption, and particularly of ‘stealth adoption’, happening outside of organisational guardrails. The panel discussion members bring their own perspectives, explaining how AI can be used successfully now, and the organisational, data management, and contractual steps needed to ensure its safe, ethical, and efficient use across complex supply chains. Guests Mark Coates, vice president of infrastructure policy alignment, Bentley Systems Yeunjin (YJ) Kim, AI technical lead, group AI, Mott MacDonald Anne-Marie Friel, partner, infrastructure, Pinsent Masons Guy Beaumont, director, digital lead, Turner & Townsend Resources The Impact of Artificial Intelligence on the Built Environment, Partner Infrastructure is too big to fail, so you need AI you can trust. Bentley Systems is delivering infrastructure-ready AI across design, construction, and operations. As the partner of choice for engineering firms and owner-operators worldwide, Bentley’s software and digital twin solutions span engineering disciplines, industry sectors, and all phases of the infrastructure lifecycle, unlocking the value of data to transform project delivery and asset performance.

This week, the UK House of Commons Environmental Audit Committee, or EAC, released a report on environmental sustainability and housing growth. The UK government is striving to meet a target of building one and a half million new homes, and has raised concerns about the risk that environmental objections could delay their construction.

In Europe, and around the world, renewable electricity generation is being built at pace. However, these sources of energy create a new challenge: they are intermittent, and will not generate power on dark, windless days. One solution to the challenge is to install grid scale storage.

It’s a simple fact of chemistry that cement cannot be produced, without also producing carbon dioxide. But this does not mean that the sector—and its clients in the construction industry—cannot decarbonise. The equally simple solution is just to capture and store the carbon dioxide, before it can enter the atmosphere. The challenge is how to...
