ILF Consulting Engineers’s water leaders once again had the privilege of attending this year’s Global Water Summit in Madrid, #Spain last week. Their key takeaway? 👉 The “water transition” is no longer a narrative challenge — it has already commenced – but is now a delivery challenge. From a consultant’s perspective, seven themes stood out: 1️⃣ Water is by now a core economic risk Water scarcity has become a hard constraint on growth — not just for utilities, but across industries and entire economies. ✅ “A large part of the global economy will operate under conditions previously unknown” (quote: José Manuel Entrecanales Domecq – Chairman & CEO, ACCIONA) 2️⃣ Demand is being reshaped by the “New Economy” Hyperscalers, semiconductors, and advanced industries are ✅ Moving away from potable water ✅ Actively seeking reuse-based supply solutions ✅ Ready to support municipalities to get these “purple pipe systems” in place → but system standards and regulations are lagging behind 3️⃣ The dials that matter most The fastest ways to address the water gap are ✅ Reducing specific agricultural water demand ✅ Reducing non-revenue water ✅ Scaling water reuse rapidly ✅ Optimizing (operation of) existing assets → None of it is glamorous, but all of it is highly effective 4️⃣ Technology is NOT the bottleneck Digital twins, smart systems, analysis with AI, advanced treatment, etc. — all available. 👉 The real constraints are a lack of institutional capacity, lack of trust in (and therefore financing for) new technologies, and poor project preparation. 5️⃣ The financing gap remains the central challenge ✅ Tariffs and/or collection don’t cover the true cost, sometimes not even OPEX ✅ Utilities lack bankability (due to lack of demonstratable cash flow) ✅ Public funding currently covers a fraction of investment needs…but accounts for 80+% of all water investment ✅ Private capital still struggles with the risk-reward imbalance → The water transition is significantly underfunded compared to energy transition (which receives at least 4x as much)…but the tide is turning 6️⃣ A clear shift toward collaborative, watershed-level thinking ✅ Municipal–industrial collaboration: industries accept that you cannot have water if your (municipal) neighbor does not ✅ Integrated planning across stakeholders → “All water is water” is gaining traction 7️⃣ The role of consultants is evolving We are no longer just “design tools” (yes, other stakeholders are finally realizing too…) 👉 We are integrators — aligning utilities, industry, regulators, and financiers 👉 And we must deliver bankable, scalable “lighthouse” projects Global Water Intelligence (GWI) Werner Redtenbacher Roberto Mangano Adil Khan Markus Klingenschmid Marc Ischen Philippe Floch Simone Puzzo ILF Consulting Engineers in Austria ILF Consulting Engineers in United Arab Emirates ILF Consulting Engineers in Pakistan #ILFConsultingEngineers #ImprovingQualityOfLife #EngineeringExcellece #GWS2026 #WaterTransition
