The best water stocks right now are Ecolab, Xylem, American Water Works, Veralto, Essential Utilities, American States Water, and California Water Service. The list spans two distinct businesses: regulated utilities that earn a guaranteed return on the pipes they own, and industrial companies that sell the pumps, meters, chemicals, and treatment systems every water system needs.
The money behind the sector is enormous and mostly non-negotiable. The EPA's most recent infrastructure survey put US drinking water needs at $625 billion over 20 years. In May, the agency confirmed it will keep its enforceable limits on PFOA and PFOS, the two most studied "forever chemicals," which forces thousands of water systems to install new treatment.
Consolidation is accelerating too. American Water Works and Essential Utilities, the two largest listed US water utilities, agreed to an all-stock merger that would create a company with a market value near $40 billion.
How We Picked
Every stock on this list trades on a major US exchange and clears a minimum market cap of $2 billion. Utilities had to show regulated rate-base growth and a dividend covered by earnings, with a payout ratio (the share of earnings paid out as dividends) under 75%. Industrial water companies had to show double-digit operating margins, positive free cash flow (the cash left over after capital spending), and a real moat in water technology or services.
We also weighted dividend track records heavily. Water is the slowest-changing sector in the market, and the companies that dominate it prove the point with some of the longest dividend growth streaks anywhere.
The 7 Best Water Stocks
Ecolab (NYSE: ECL)
Why it made the list: Ecolab is the global leader in water treatment and hygiene services for businesses, helping hotels, hospitals, food plants, and data centers use less water and reuse more of it. Net profit margin runs near 13% and gross margin above 44%.
The bull case: Water scarcity turns Ecolab's core pitch, cutting a customer's water bill, into a boardroom priority. The company generated more than $3 billion in operating cash flow over the last four quarters and pays out only about 37% of earnings as dividends, leaving room for years of increases.
The risk: The stock trades at roughly 38 times trailing earnings, the richest multiple on this list. Any growth stumble gets punished at that price.
Key number: More than $3 billion in operating cash flow over the trailing twelve months.
Xylem (NYSE: XYL)
Why it made the list: Xylem is the closest thing to a pure-play water technology stock at scale. It makes the pumps, smart meters, leak-detection systems, and treatment equipment utilities buy when they modernize, and its Evoqua acquisition made it a leader in the exact treatment technology PFAS rules require.
The bull case: Every dollar of the EPA-driven treatment buildout and the smart-meter upgrade cycle flows through companies like Xylem. The dividend eats just 41% of earnings, and operating profits cover interest costs roughly 49 times over.
The risk: A large share of the business serves industrial customers, so a manufacturing slowdown hits orders. The stock also sits more than 20% below its 52-week high after a soft stretch.
Key number: A 41% payout ratio, leaving most earnings free for reinvestment and buybacks.
American Water Works (NYSE: AWK)
Why it made the list: American Water Works is the largest publicly traded water and wastewater utility in the US, serving about 14 million people across 14 states plus 18 military installations. Regulators let it earn a set return on every dollar of approved investment, and it plans to invest $46 to $48 billion from 2026 through 2035.
The bull case: Management guided to 8% earnings growth this year and targets 7% to 9% long term, unusually fast for a utility. The pending all-stock merger with Essential Utilities adds water and gas customers across new states and creates the sector's undisputed heavyweight.
The risk: Heavy construction spending means the company pays its dividend while running negative free cash flow, a normal utility model that still depends on regulators approving rate increases on schedule.
Key number: $46 to $48 billion in planned capital investment through 2035.
Veralto (NYSE: VLTO)
Why it made the list: Veralto was spun out of Danaher in late 2023 and owns Hach and ChemTreat, the instruments and chemistry that labs and plants use to test and treat water. Operating margin runs above 23%, and nearly every dollar of operating cash flow converts to free cash flow because the business barely needs capital spending.
The bull case: Water testing is regulation-driven, recurring, and sticky. Tighter contaminant rules mean more tests per system, and Veralto's payout ratio near 12% gives it one of the longest dividend growth runways in the sector.
The risk: The dividend yield is only about 0.5%, so income investors get little today. The valuation assumes the recurring-revenue machine keeps compounding.
Key number: About 95% of operating cash flow converts to free cash flow.
Essential Utilities (NYSE: WTRG)
Why it made the list: Essential Utilities runs Aqua, one of the largest US water utilities, plus a Pennsylvania natural gas distributor. It agreed in October to merge with American Water Works in an all-stock deal expected to close by the end of the first quarter of 2027, with shareholder votes done and approvals already secured in Kentucky, Ohio, and Virginia.
The bull case: Investors get paid a dividend yield near 3.5%, the highest on this list, while holding a claim on the combined company. The stock is effectively a lower-priced entry into American Water with more income attached.
The risk: Mergers between regulated utilities can be delayed or blocked by any state commission that still has to sign off. A broken deal would send the shares back to trading on their own fundamentals.
Key number: A dividend yield near 3.5% while the merger is pending.
American States Water (NYSE: AWR)
Why it made the list: American States Water has raised its dividend for 71 consecutive years, the longest streak of any publicly traded company. It serves about a million Californians and runs water systems on US military bases under 50-year government contracts.
The bull case: The military contract business adds unregulated, long-duration revenue no other water utility can match. Management targets long-term dividend growth above 7% a year, and the five-year growth rate has run near 8.5%.
The risk: At nearly 25 times earnings, the record is priced in. Most of the regulated business sits in California, concentrating regulatory and drought risk in one state.
Key number: 71 consecutive years of dividend increases, the longest streak in the market.
California Water Service (NYSE: CWT)
Why it made the list: California Water Service is one of the largest listed US water utilities, serving customers in California, Washington, New Mexico, Hawaii, and Texas. In January it announced its 59th consecutive annual dividend increase, lifting the annual payout 8% to $1.34 per share.
The bull case: The multi-state footprint is quietly diversifying away from pure California exposure, and the payout ratio near 62% still leaves room for the streak to continue. The stock recently traded near its 52-week high, a sign the market is rewarding the execution.
The risk: Wildfire liability and drought politics are permanent features of a California-centered utility. Capital spending currently exceeds operating cash flow, so the company leans on debt and equity to fund growth.
Key number: 59 consecutive annual dividend increases, including an 8% raise this year.
Water Stocks at a Glance
The Water Sector Right Now
Two forces are reshaping the sector at once. The first is regulation. The EPA confirmed in May that it will keep its maximum contaminant limits on PFOA and PFOS, the strictest drinking water standards ever set, while proposing to let water systems request two extra years, to 2031, to comply. A maximum contaminant limit is the highest level of a substance legally allowed in tap water. Meeting the new limits requires activated carbon or ion exchange treatment at thousands of systems, spending that flows to equipment makers like Xylem and Veralto and gets added to the rate base at utilities like American Water. Rate base is the pool of invested capital a regulator lets a utility earn a return on, which is why utilities treat mandated spending as growth rather than cost.
The second force is consolidation. The US has roughly 50,000 community water systems, most of them small, municipally owned, and starved for capital. Large utilities grow by buying them, and the American Water and Essential Utilities merger is the biggest expression of that logic yet. The sector's steady, rate-regulated model is the same reason utility stocks broadly appeal to income investors, and the dividend records here rival anything on our list of the best dividend stocks.
Water utilities also trade like bond substitutes, which cuts both ways. When Treasury yields fall, these stocks tend to re-rate higher, the same dynamic that drives the best retirement income stocks.
What to Watch
-
The PFAS compliance rule. The EPA's public comment period on the proposed 2031 extension closes July 20. A finalized timeline turns a multibillion-dollar treatment buildout into scheduled orders for Xylem, Veralto, and Ecolab.
-
Merger approvals. The American Water and Essential Utilities deal has cleared Kentucky, Ohio, and Virginia but still needs the remaining state commissions and federal antitrust clearance. Closing is expected by the end of the first quarter of 2027.
-
Interest rates. Utility valuations move opposite Treasury yields. Any Fed easing would be a direct tailwind for AWK, AWR, CWT, and WTRG.
Bottom Line
Water is the rare sector where demand is guaranteed, spending is mandated by law, and the leading companies have proven their models across half a century of dividend checks. Investors wanting maximum safety should start with American Water Works or the 71-year streak at American States Water. Investors wanting growth from the same trend should look at Xylem and Veralto, which sell the equipment every mandate requires. Essential Utilities offers the sector's best yield plus a merger kicker while the deal works toward closing.
Frequently Asked Questions
What is the best water stock to buy?
American Water Works is the strongest single pick for most investors. It is the largest listed US water utility, plans $46 to $48 billion in capital investment through 2035, and guides to long-term earnings growth of 7% to 9%. Investors who prefer growth over income should consider Xylem, the leading pure-play water technology company.
Do water stocks pay good dividends?
Yes, and their track records are among the best in the market. American States Water has raised its dividend for 71 consecutive years, the longest streak of any public company, and California Water Service just posted its 59th straight annual increase. Essential Utilities yields about 3.5%, the highest on this list.
Are water stocks a good long-term investment?
Water demand does not fall in recessions, and regulators guarantee utilities a return on invested capital, which makes the sector one of the most durable in the market. The trade-off is modest growth and sensitivity to interest rates, since income investors rotate out of utilities when bond yields rise.
What is the safest water stock?
American States Water and California Water Service have the longest proof of resilience, with dividend increases spanning every recession since the 1950s and 1960s. Among larger names, American Water Works pairs scale with regulated revenue in 14 states.
Is there an ETF for water stocks?
Yes. The Invesco Water Resources ETF (PHO), First Trust Water ETF (FIW), and Invesco S&P Global Water Index ETF (CGW) all hold baskets of water utilities and water technology companies, including most of the names on this list.
