Best Water Stocks to Buy in 2026: 6 Top Water Companies
Introduction
The best water stocks to buy in 2026 offer investors exposure to one of the world’s most essential resources. Aging infrastructure, global water scarcity, industrial demand, and the rapid expansion of AI data centers are creating new investment opportunities across water utilities, treatment technologies, filtration, and infrastructure.
For investors, the sector offers an unusual combination of defensive characteristics and long-term growth. Regulated utilities can provide relatively predictable cash flows, while water technology and infrastructure companies can benefit from rising investment in treatment, efficiency, and modernization.
The infrastructure challenge alone is enormous. The U.S. Environmental Protection Agency estimates that drinking water systems will require approximately $625 billion of investment over 20 years for pipe replacement, treatment plant upgrades, storage tanks, and other essential infrastructure.
Artificial intelligence is adding another potential source of demand. Data centers require substantial cooling infrastructure, and rapid AI expansion is increasing attention on water availability, recycling, treatment, and efficiency.
In this guide, we compare six of the best water stocks for 2026, including Xylem, American Water Works, Pentair, Veolia, Advanced Drainage Systems, and Danaher.
Why Water Stocks Are a Smart Investment in 2026
Water investing is supported by several long-term trends that could persist for decades.
AI Data Centers Are Increasing Water Infrastructure Demand
Artificial intelligence requires enormous computing infrastructure.
Many large data centers use water-based cooling systems to remove heat generated by servers and other equipment.
A 2026 study involving researchers from UC Riverside and Caltech estimated that, without additional efficiency improvements, U.S. data centers could require 697 million to 1.45 billion gallons per day of additional peak water capacity by 2030.
This does not mean every data center will consume enormous quantities of drinking water directly. Cooling technologies vary significantly between facilities.
However, rapid data center expansion creates another reason for utilities and technology companies to invest in water treatment, recycling, monitoring, cooling efficiency, and infrastructure.
Companies positioned in these areas could benefit as AI infrastructure expands.
Aging Water Infrastructure Requires Massive Investment
Much of the water infrastructure in the United States is aging.
Pipes, treatment plants, pumps, storage systems, and monitoring technologies require continuous maintenance and replacement.
The EPA’s latest Drinking Water Infrastructure Needs Survey estimates approximately $625 billion in infrastructure needs over the next 20 years.
Companies providing pumps, filtration systems, treatment technologies, pipes, monitoring equipment, and engineering solutions could benefit from this long-term modernization cycle.
Global Water Scarcity Is Getting Worse
Water scarcity is becoming an increasingly important economic challenge.
Population growth, urbanization, industrial development, drought, agriculture, and climate change are putting additional pressure on freshwater resources.
Governments and businesses are therefore investing in:
- Water recycling
- Wastewater treatment
- Desalination
- Leak detection
- Smart metering
- Filtration
- Efficient irrigation
- Industrial water reuse
These investments create opportunities across multiple segments of the water industry.
Water Utilities Can Provide Defensive Characteristics
Consumers and businesses require water regardless of economic conditions.
That makes regulated water utilities relatively defensive compared with many cyclical industries.
Utilities can also benefit from approved infrastructure investment programs that expand their regulated asset bases over time.
For long-term investors, this combination of essential demand and infrastructure investment can make water utilities attractive portfolio holdings.
Best Water Stocks to Buy in 2026 at a Glance
| Company | Ticker | Primary Water Exposure | Best For |
|---|---|---|---|
| Xylem | XYL | Water technology & infrastructure | Growth |
| American Water Works | AWK | Regulated water utility | Defensive investors |
| Pentair | PNR | Filtration & treatment | Water quality |
| Veolia | VEOEY | Global water & environmental services | International exposure |
| Advanced Drainage Systems | WMS | Drainage & water infrastructure | Infrastructure growth |
| Danaher | DHR | Water quality technology | Diversified exposure |
These companies provide different ways to invest in the water sector. Some offer relatively direct exposure to utilities and infrastructure, while others combine water technologies with broader industrial or life-sciences businesses.
1. Xylem (NYSE: XYL) — Best Water Technology Stock
Xylem is one of the world’s largest pure-play water technology companies.
The company provides technologies used across the entire water cycle, including water transportation, treatment, testing, monitoring, metering, and wastewater management.
Its products serve municipalities, utilities, industrial customers, and commercial organizations around the world.
Why Xylem Stands Out
Xylem benefits from several major trends simultaneously.
Aging infrastructure creates demand for pumps, treatment systems, smart meters, and monitoring technologies.
Water scarcity encourages utilities to reduce leakage and improve efficiency.
Industrial customers increasingly need advanced treatment and water reuse systems.
AI data center expansion could create additional demand for water management and treatment technologies.
The company has also strengthened its water treatment capabilities through its combination with Evoqua.
2026 Business Momentum
Xylem reported $2.1 billion of revenue in the first quarter of 2026, up 3% on a reported basis. Adjusted earnings per share reached $1.12.
Management also forecast approximately $9.2 billion to $9.3 billion in full-year 2026 revenue following its first-quarter results.
Later in 2026, the company raised its profit outlook following stronger demand, including demand connected with AI-related water-treatment infrastructure.
Key Growth Drivers
- Smart water infrastructure
- Wastewater treatment
- AI data center cooling
- Digital monitoring
- Water recycling
- Infrastructure modernization
- Industrial water treatment
- Leak detection
Risks
Xylem is not a cheap utility stock.
Its valuation can reflect expectations for long-term growth, meaning weaker industrial demand or slower infrastructure spending could create share-price volatility.
Still, investors seeking relatively direct exposure to water technology may find Xylem one of the strongest publicly traded candidates.
2. American Water Works (NYSE: AWK) — Best Water Utility Stock
American Water Works is one of the largest publicly traded water and wastewater utilities in the United States.
The company provides essential water services to residential, commercial, and industrial customers.
Unlike higher-growth water technology companies, American Water Works offers investors more traditional utility exposure.
Why American Water Works Stands Out
Water demand is highly defensive.
Customers still need drinking water and wastewater services during recessions, periods of inflation, and market volatility.
The company’s regulated business model allows it to invest in infrastructure and seek regulatory approval to earn returns on those investments.
That creates a potentially predictable long-term growth model.
Infrastructure Investment Opportunity
American Water Works continually invests in:
- Pipe replacement
- Treatment facilities
- Storage
- Pumping infrastructure
- Water quality
- Wastewater systems
- Digital monitoring
Aging U.S. water infrastructure creates a long runway for continued investment.
Dividend Appeal
American Water Works also appeals to dividend-growth investors.
The company has historically increased its dividend while expanding its regulated utility operations.
For investors prioritizing stability rather than maximum growth, AWK provides a different risk profile from companies such as Xylem or Advanced Drainage Systems.
Risks
Water utilities are capital-intensive businesses.
Higher interest rates can increase financing costs, while regulators determine how quickly utilities can recover infrastructure investments through customer rates.
The stock can also trade at premium valuation multiples because of its defensive characteristics.
3. Pentair (NYSE: PNR) — Best Water Filtration Stock
Pentair provides water treatment, filtration, flow management, and pool technologies.
Its products serve residential, commercial, and industrial customers.
The company’s portfolio gives investors exposure to increasing demand for clean water and efficient water management.
Why Pentair Stands Out
Pentair participates in several attractive water markets.
Its filtration technologies help improve water quality.
Flow management products help move and control water efficiently.
The company also maintains significant exposure to residential pool equipment.
Long-Term Growth Drivers
Potential long-term catalysts include:
- Residential water filtration
- Commercial treatment
- Water efficiency
- Replacement equipment
- Connected water systems
- Industrial treatment
Growing concerns about drinking water quality could support long-term demand for filtration technologies.
Important 2026 Risk
Pentair also demonstrates why investors should not assume every water stock will move higher simply because the industry’s long-term outlook is attractive.
In July 2026, the company sharply reduced its full-year sales outlook following weaker performance, particularly within its pool business.
That development increased near-term uncertainty and demonstrates Pentair’s greater cyclical exposure compared with regulated water utilities.
Risks
Pentair has meaningful exposure to housing, consumer spending, and the pool market.
Economic weakness or inventory adjustments can therefore affect results.
Investors should distinguish between the company’s attractive long-term water exposure and shorter-term operational risks.
4. Veolia Environnement — Best Global Water Stock
Veolia is one of the world’s largest environmental services companies.
The France-based company operates across water management, wastewater treatment, waste management, energy services, and industrial environmental solutions.
Its enormous international footprint gives investors exposure to water infrastructure across multiple geographic markets.
Why Veolia Stands Out
Veolia operates water and wastewater systems for cities and industrial customers around the world.
Its services include:
- Drinking water treatment
- Wastewater management
- Desalination
- Industrial water treatment
- Water reuse
- Environmental services
- Resource recovery
The company can benefit from stricter environmental regulations and growing demand for sustainable water management.
AI and Industrial Water Opportunity
Large industrial facilities and data centers require reliable access to water while increasingly facing pressure to minimize consumption.
Veolia can provide treatment, recycling, and reuse technologies that help industrial customers reduce freshwater requirements.
This could become increasingly important as AI infrastructure expands.
Dividend
Veolia’s shareholders approved a €1.50-per-share cash dividend for fiscal 2025, paid in May 2026.
That was higher than the €1.40 dividend for fiscal 2024.
Risks
Veolia’s operations extend well beyond water.
Investors also receive exposure to waste management, energy services, environmental regulation, currencies, and international economic conditions.
This makes Veolia less of a pure-play water investment than Xylem or American Water Works.
5. Advanced Drainage Systems (NYSE: WMS) — Best Water Infrastructure Stock
Advanced Drainage Systems manufactures drainage and water-management products used in construction and infrastructure.
Its products help manage stormwater and move water safely through residential, commercial, agricultural, and municipal environments.
Why Advanced Drainage Systems Stands Out
Extreme rainfall, urban development, and aging drainage infrastructure are increasing the importance of stormwater management.
Cities and developers need systems capable of controlling runoff and reducing flooding risks.
Advanced Drainage Systems provides products used in these projects.
Infrastructure Opportunity
The company’s long-term opportunities include:
- Stormwater management
- Drainage infrastructure
- Highway construction
- Residential development
- Commercial construction
- Agricultural water management
- Municipal infrastructure
Climate adaptation spending could create another source of demand.
Sustainability Advantage
Advanced Drainage Systems is also known for using recycled materials in many of its products.
This can provide an environmental advantage while helping customers replace traditional infrastructure materials.
Risks
Unlike regulated utilities, Advanced Drainage Systems is exposed to construction cycles.
Housing weakness, slower commercial construction, or reduced infrastructure spending can affect demand.
The stock may therefore experience greater volatility than defensive water utilities.
6. Danaher (NYSE: DHR) — Best Diversified Water Quality Stock
Danaher is not a pure-play water company.
The company primarily operates across life sciences, diagnostics, and biotechnology-related technologies.
However, its portfolio also provides exposure to water quality and analytical technologies.
Why Danaher Belongs on the List
Water treatment requires more than pumps and pipes.
Utilities and industrial facilities must continuously test water for contaminants, chemicals, microorganisms, and other quality indicators.
Analytical technologies can help organizations monitor these conditions accurately.
This gives Danaher indirect exposure to water quality infrastructure.
Diversification Advantage
Danaher differs significantly from the other companies on this list.
Investors receive exposure not only to water-related technologies but also to:
- Life sciences
- Diagnostics
- Bioprocessing
- Laboratory technology
- Analytical instruments
This diversification can reduce dependence on the water industry.
Risks
The same diversification is also the main limitation.
Water represents only part of Danaher’s broader investment thesis.
Investors seeking direct exposure to water infrastructure may prefer Xylem, American Water Works, or Advanced Drainage Systems.
AI Data Centers and the Water Investment Opportunity
One of the most interesting developments for water investors in 2026 is the rapid expansion of artificial intelligence infrastructure.
AI models require large amounts of computing power.
That computing power generates heat.
Depending on the design and location of a data center, water can play an important role in cooling infrastructure.
A UC Riverside and Caltech research project estimated that U.S. data centers could require hundreds of millions of gallons of additional peak water capacity per day by 2030 if efficiency improvements fail to keep pace with computing growth.
This creates opportunities across several parts of the water ecosystem.
Water Treatment
Data centers require water with appropriate quality characteristics for cooling systems.
Treatment technologies can remove minerals and contaminants that might otherwise damage equipment.
Water Recycling
Operators are increasingly exploring recycled and non-potable water sources.
This can reduce competition with municipal drinking-water supplies.
Cooling Efficiency
More efficient cooling technologies can reduce both water and electricity consumption.
Smart Monitoring
Digital sensors and analytics can identify leaks, monitor water quality, and optimize cooling-system performance.
Companies such as Xylem and Veolia are particularly relevant to this infrastructure theme.

Water Infrastructure Investment Opportunity
AI data centers represent only one source of demand.
The much larger long-term story remains modernization of traditional water infrastructure.
The EPA estimates that U.S. drinking-water systems require approximately $625 billion of infrastructure investment over 20 years.
Investment is needed across:
- Water mains
- Treatment facilities
- Storage
- Pumping equipment
- Lead service line replacement
- Monitoring technology
- Distribution systems
This creates opportunities for utilities, equipment manufacturers, engineering companies, and technology providers.
Infrastructure investment can also be relatively durable because communities cannot indefinitely postpone essential repairs.
