Water is one of the world’s most critical resources and yet it remains one of the most overlooked asset classes. While tech and AI dominate headlines, a quieter revolution is underway in water infrastructure, utilities, and water-management companies. Billionaires and institutional investors are increasing their exposure to this sector because they see steady growth, regulatory tailwinds, and essential demand that never goes away.

Below are some of the top water stocks and ETFs that reflect this trend. I’ll explain why each is worth attention, and you can drop your charts under each stock to spot buy points.

Top Water Stocks Gaining Interest

American Water Works (AWK)

American Water Works is a utility focused purely on water and wastewater services across many U.S. regions. It holds appeal because its revenue comes from essential services. When demand for clean water remains constant, AWK delivers cash flow that is both resilient and predictable.

Severn Trent PLC

Severn Trent provides drinking water and wastewater services in the UK. For investors who value regulated revenues, Severn Trent stands out. Its government oversight ensures rates adjustments yield returns, and its infrastructure needs are driving maintenance and upgrade spending now.

United Utilities

This utility company also operates in the UK and serves a large population with water and waste services. Rising concerns over environmental compliance, aging pipes, and water quality make United Utilities an attractive pick. It offers both dividend stability and long-term growth prospects.

Badger Meter (BMI)

Badger Meter supplies meters, flow monitoring tools, and instrumentation. As governments push for smarter usage tracking, leak prevention, and efficiency, companies like BMI gain demand. Their products play a hidden but crucial part in conserving water.

Mueller Water Products (MWP)

Mueller makes hydrants, valves, fire hydrants, and related components. These are essential parts of water infrastructure. With many regions facing infrastructure gaps, the kind of hardware Mueller provides is being budgeted into public spending.

SABESP (Companhia de Saneamento Básico do Estado de São Paulo) (SBS)

SABESP is a major water and sewage services provider in Brazil. Emerging markets have urgent need for clean water and sanitation, and growing urban populations make companies like SABESP essential. Economies with rising middle class demand long-term infrastructure investment.

It holds about 38 stocks and charges a 0.59% expense ratio, with leading positions in Ferguson, Xylem, and Ecolab. Annual returns have averaged about 9% since its launch in 2005.

• First Trust Water ETF

The First Trust Water ETF (FIW) is designed to reflect the performance of US-listed water industry companies, including utilities and equipment suppliers. It typically owns 37 to 40 holdings, charges a 0.51% expense ratio, manages around $2 billion in assets, and includes names like Ferguson, IDEXX Laboratories, and Xylem.

Each of these allows you to gain exposure across different segments of the water industry utilities, hardware/parts, global names reducing single company risk while riding the broader rise.

What Billionaires Look For in Water Investments

Those putting serious money into water are watching for several key signals:

• Infrastructure spending at both federal and local levels
• Regulatory support for water quality, leak mitigation, and sustainability
• Companies with monopoly or regional utility status because they have pricing power
• Products and technologies that support smarter water use (meters, sensors, flow control)
• ESG mandates and climate pressure that push clean water access into focus
