Water shortages thesis

Been thinking about this since 2025 - finally pulled the trigger. Tell me why I am a genius or a moron depending on your provaction. **My thesis:** Water infrastructure is chronically underinvested, and three separate tailwinds are converging at once: aging pipe replacement, PFAS regulation forcing new filtration and testing capex, and the one that's all the rage - AI data centres and semiconductor fabs needing huge volumes of process and cooling water, see also growing interest in nuclear energy and droughts / climate change. The UK hasn't built a single reservoir since 1992! Rather than buy a water ETF and pay 0.6%+ a year for a basket that's roughly half non-pure-play names, I built my own 10-stock pie: a growth/technology tier (water equipment, chemicals, testing) sitting on top of a defensive tier (regulated water utilities). My split is roughly **63% growth/technology/equipment** (Xylem, Ecolab, Veralto, Watts, Pentair, Advanced Drainage) against **37% regulated utilities** (AWK, Essential Utilities, United Utilities, Severn Trent). It's deliberately tilted toward the growth side rather than a defensive-heavy split — I'm underwriting the capex supercycle and PFAS-driven demand as the bigger driver, with the utilities there mainly for rate-base earnings visibility and dividend ballast, not as the main return engine. Currently a modest position (\~£1,500), built to grow over time. I aim to have it at 10% of my portfolio (breakdown below) \- 85% VWRP \- 10% GOOGLE \- 5% WATER (increasing to 10%) - Xylem 15%, American Water Works 12%, Ecolab 12%, Veralto 12%, Advanced Drainage Systems 10%, Essential Utilities 10%, Watts Water Technologies 9%, United Utilities 8%, Severn Trent 7%, and Pentair 5%. Core points: * The World Economic Forum puts the total global investment needed for resilient water and sanitation systems at **$13.2 trillion by 2040**. * US municipal water and wastewater capex is forecast to cross **$100 billion a year by 2030**, up from current levels, driven by tightening federal PFAS rules, lead service line replacement deadlines, and drought-driven desalination spend in states like Texas. * The EPA's finalised PFAS drinking water rules force utilities of every size to test, monitor and treat for "forever chemicals" a direct, multi-year revenue driver for testing and filtration specialists. * Slide back towards ''Realism'' in global politics making commodities more valuable, I even foresee water wars in the not too distant future. Core risks: * The lack of diversification within this pie given its just 10 holdings, * Currency - Its mostly USD * Nationalisation of UK water * **Valuation risk on the growth tier.** Xylem and Veralto are pricing in a good chunk of the capex supercycle already, however I think PE ratios are reasonable * Trump et al, decide that water safety testing is ''woke'' and projects / funding are cut. I expect very little movement in this pie in the short term, or at least not outpacing market beta - however a massive jump when we're in the 'find out' stage from our ''fucking about'' with water and then massive capex spending and valuations jumps - hence buy now whilst ''cheap'.
