Surface water management is becoming one of the most critical challenges in modern construction. With heavier rainfall, complex planning requirements, and increasing pressure on land values, traditional drainage methods are struggling to cope. In this Hard Hat Talks episode, host Kenneth Martin speaks with Frank O’Donnell, Principal Consultant at Groundwater Dynamics, to uncover why a smarter, zero-maintenance approach to SuDS is transforming developments across Scotland and the wider UK.Frank explains how climate change is exposing the limitations of ponds, swales, and permeable paving - systems that often fail, clog, or come with costly long-term maintenance responsibilities. At the heart of the conversation is Groundwater Dynamics’ Tier 1 SuDS solution, a fully underground, geocellular system that captures, cleans, and slowly releases surface water at a controlled rate. With no moving parts and no siltation issues, it offers a rare benefit in drainage design: true zero maintenance.The episode dives into one of Scotland’s biggest blockers to development - the adoption issue. Many drainage systems are refused by Scottish Water because they require ongoing maintenance. Frank explains how Tier 1 Source Control overcomes this barrier while unlocking commercial value by freeing up land normally lost to attenuation ponds.You’ll also hear why early engagement is essential, how poor drainage planning can force late-stage redesigns, and what developers, architects, and engineers can do to avoid costly delays. From water quality to system longevity, the discussion provides a clear, practical roadmap for those looking to build smarter, more resilient projects.Whether you work in architecture, engineering, planning, development, or construction management, this episode offers insight into the future of SuDS - and how underground infrastructure can help us adapt to a changing climate.In this episode, you’ll learn:Why climate change is increasing localised flooding and overwhelming traditional drainageHow Tier 1 SuDS support Source Control - the preferred starting point of the SuDS management trainWhy Scotland faces an adoption crisis with ponds, swales, and above-ground systemsThe commercial value of underground drainage that maximises usable landHow early design engagement prevents costly reworks and lost development spaceWhy systems fail - and how pre-treatment and proper design prevent blockagesThe future of water re-use, rainwater harvesting, and water-efficient developmentsHow free CPD training is helping designers and consultants avoid common SuDS mistakesStay tuned to the end where Frank leaves his question for the next Hard Hat Talks guest:“What are the two most important qualities you look for in a business partner or an employee?”If you enjoy the episode, follow Hard Hat Talks for more honest conversations with the people shaping the built environment.
