This mix isn’t a surprise. Actually, it’s a assortment of a number of long-term developments that exemplify water’s standing because the world’s most vital useful resource.
“With out water, there is no such thing as a financial system,” says Saurabh Sharma, fund supervisor at Regnan Sustainable Water and Waste Fund. “We can’t have a sustainable financial system with out waste administration. Waste is a vital a part of our each day lives. If both one stops working, your complete financial system collapses.”
In 2023, the World Wildlife Fund assessed the financial worth of the world’s water techniques for the primary time, calculating the financial worth to be $58 trillion yearly. That is equal to 60% of worldwide GDP.
“Nevertheless, entry to water is turning into more and more tough for almost all of the world’s inhabitants,” says Jasmine Savage, funding supervisor at Foresight Group. This is applicable to each rising markets and developed nations such because the US and UK.
“This mismatch between provide and demand is widening, with international water demand projected to exceed out there assets by roughly 40% by 2030,” Savage mentioned.
Structural tailwind of water
As a result of ubiquity of water, the funding case for water is pushed by a number of long-term developments.
Marc-Olivier Bulle, Head of Thematic Consumer Portfolio Administration, Sustainability & Analysis at Pictet Asset Administration, focuses on long-term structural modifications, or “megatrends” that play out over many years, a few of which he believes will affect the thesis of water investing.
One of many main ones is urbanization. Within the Fifties, roughly 30% of the world’s inhabitants lived in cities. This quantity is anticipated to exceed 50% by 2011 and rise to 70% by 2050.
“You’ll be able to’t construct environment friendly cities with out correct water infrastructure and correct water networks, each on the ingesting water aspect and the waste administration aspect,” says Baffle.
One other megatrend that Baffle and his group connect with water is society’s rising well being consciousness.
“The overall pattern is in direction of delivering water from the faucet that’s utterly freed from microorganisms, micro organism and viruses, in addition to chemical compounds and micropollutants.”
Per- and polyfluoroalkyl substances (PFAS), often known as “everlasting chemical compounds,” are a distinguished instance on the contaminant entrance. These artificial compounds are utilized in a variety of merchandise, from non-stick pots to waterproof jackets, and have been proven to have important well being results even at low concentrations, however they accumulate in water techniques.
Governments are starting to tighten laws on PFAS. Whereas this could possibly be a headwind for water suppliers, it presents a possibility for different firms within the worth chain growing techniques to observe and analyze the degrees of those chemical compounds in water techniques.
One other megatrend is local weather change. This creates issues for water infrastructure firms within the type of both too little water (droughts) or an excessive amount of water (floods).
“With local weather change, these excessive circumstances have gotten more and more frequent, making a must develop new infrastructure to make water techniques extra resilient,” says Baffle.

Equally, Savage divides his principle of water funding into three pillars. These are a rising supply-demand imbalance, continual underinvestment in water infrastructure, and environmental and air pollution issues.
When it comes to addressing these long-term elements, it helps to categorize the kinds of firms that make up the world of water firms wherein to take a position.
Investing throughout the water worth chain
Not all water investments are equal.
The water firms most of us are acquainted with on a day-to-day foundation, Severn Trent (LON:SVT), United Utilities (LON:UU.) and Pennon Group (LON:PNN), are utility firms and subsequently play an in depth defensive function of their portfolios. They’ve regular demand all through the cycle (nobody cuts again on water utilization throughout a recession) and generate predictable compounding revenue.
Because of this regulation, water utility firms have good visibility into medium-term (3-5 years forward) earnings and capital expenditures, permitting them to pay very steady dividends.
The broader the worth chain within the water funding setting, the extra various it turns into. It consists of producers of water remedy techniques, tools suppliers, water evaluation firms that monitor water high quality ranges, and development firms that construct reservoirs, waterways, and so forth.
Gear producers embody Xylem (NYSE:XYL), Thermo Fisher Scientific (NYSE:TMO), and Agilent (NYSE:A). All three firms are concerned in manufacturing merchandise for PFAS monitoring and/or remedy, ultrapure water, and plenty of different points of water administration.
The water trade sells to utility firms as an finish market. These are extra delicate to the financial system and may be extra cyclical, but additionally provide traders short-term development potential. These are, in impact, rigorously chosen shares for water funding.
Nevertheless, whereas the water trade has larger development potential than utility firms, it additionally advantages to some extent from the theme’s total defensive energy.
“Industrial firms may even profit from a reasonably steady demand base if the utilities themselves have good visibility into their three- to five-year capital and working spending packages,” Savage says.
Quick-term water tailwind
Whereas a lot of the water drivers are long-term and structural, there are additionally some short-term developments impacting the sector.
Considered one of these is the demand for ultrapure water. This can be a notably vital enter in semiconductor manufacturing and different industrial processes.
“When making small chips, you want clear water with all impurities eliminated,” says Sharma.
For instance, a Japanese firm known as Organo (TSE: 6368) provides water to Taiwan Semiconductor Company’s (TSMC) operations. Organo successfully operates the service as a result of firms like TSMC require a steady provide of very top quality water and require Organo engineers on web site to make sure that provide. It is also a high-margin enterprise, given the extent of earnings out there to semiconductor producers.
As such, elevated spending on AI information facilities (that are themselves identified to be water-intensive) is driving demand for this a part of the water market.
The right way to put money into water
Investing in water acts as a diversifier to your portfolio. As a result of a lot of the demand elements are long-term and structural, this theme as a complete is much less inclined to financial ups and downs that have an effect on different elements of the inventory market.
Nevertheless, there are a number of kinds of water firms, which might present alternatives for development in addition to safety.
Most water funds seize this duality of water investing. Pictet Water takes a barbell method to offering steady and dependable income by means of its water operations, in addition to development potential by means of the extra industrial parts of the water ecosystem.
“You need to be capable to get comparatively good returns in good occasions, but additionally some safety in occasions of busts and financial uncertainty,” Baffle says.
As of November 28, 2025, Regnan’s Sustainable Water and Waste Fund is allotted roughly 18% to utilities and roughly 64% to trade. The rest of the fund is primarily dedicated to client discretionary and supplies shares.
