The water bill on the kitchen counter keeps climbing even when usage does not. That is not a one-town quirk. Across dozens of large U.S. cities, household water and sewer charges rose faster than overall inflation again in 2025, and the utilities that own the pipes are spending billions to replace aging mains, treat contaminants and win rate cases that fund the work.
For investors, regulated water companies look like slow compounders: rate base grows with capital spending, regulators allow a return on that investment, and dividends tend to rise with earnings. For households, the same cycle shows up as higher monthly bills and a reminder that clean water is becoming a larger share of the fixed cost of staying in a home.
- Bluefield Research: U.S. household water and sewer bills rose 5.1% in 2025, a five-year high year over year, and are up a cumulative 24.2% from 2020 through 2025 across the firm's 50-city Municipal Water and Sewer Rate Index.
- American Water filings: since Jan. 1, 2026 the company authorized $216 million of additional annualized revenues, still has about $494 million of incremental rate requests pending, spent $1.8 billion of capital in the first half, and affirms 2026 adjusted EPS guidance of $6.02 to $6.12.
- Essential Utilities filings: first-half infrastructure investment reached $662.2 million on a $1.7 billion 2026 plan, 2026 year-to-date water rate awards and surcharges totaled $43.9 million annualized, and the company affirms a multiyear EPS CAGR of 5% to 7% through 2027.
- Bluefield Research and related cost data: from January 2000 through December 2025, water, sewer and trash prices rose about 207% versus overall inflation of about 93%, and covering a monthly water and sewer bill still takes an average 11.5 hours of minimum-wage labor.
Why bills keep rising
Bluefield Research's March 2026 Municipal Water and Sewer Rate Index tracks typical household bills in 50 large U.S. cities. Combined water and sewer bills rose 5.1% in 2025, the fastest year-over-year jump in five years and still ahead of general consumer inflation. Water rates alone were up 6.0% from 2024 to 2025, while wastewater rose 4.8%. Over the five years from 2020 through 2025, the cumulative increase was 24.2%.
The cost stack is familiar. Aging distribution and collection systems need replacement. Electricity, treatment chemicals and construction materials all rose. Financing costs matter when utilities borrow for multi-year projects. Regulatory compliance, including PFAS treatment rules, adds plant and operating expense that eventually seeks recovery in rates.
Geography still matters. Bluefield found Northeast average bills near $147 a month and West averages near $143, the highest regional levels in the survey. Over the past five years, sewer averaged $19.23 per month above water charges. Stretch that back further and the gap versus overall prices is stark. From January 2000 through December 2025, water, sewer and trash prices rose about 207%, versus overall inflation of about 93%. Covering a typical monthly water and sewer bill still requires about 11.5 hours of work at the federal minimum wage, according to the firm.
American Water: rate cases funding a $3.7 billion capital year
American Water Works is the largest publicly traded U.S. water and wastewater utility, serving about 14 million people through regulated operations in 14 states and 19 military installations. In its second-quarter 2026 results, the company reported GAAP and adjusted earnings of $1.61 per share, up from $1.48 and $1.49 a year earlier. Operating revenues were $1.355 billion in the quarter and $2.562 billion in the first half. Regulated Businesses net income was $331 million in the quarter, up from $288 million.
Since Jan. 1, 2026, American Water said it had authorized $216 million of additional annualized revenues, split between $111 million from general rate cases and $105 million from infrastructure surcharges. Another roughly $494 million of annualized incremental revenue was still pending across general rate cases in six jurisdictions plus one infrastructure surcharge request. Pennsylvania rates from a constructive decision became effective Aug. 13.
First-half capital investment was $1.8 billion, including $346 million of regulated acquisitions, and management said the full-year plan of about $3.7 billion remained on track. Acquisitions added about 52,000 customer connections through June 30, including Nexus Water. The company affirmed 2026 adjusted EPS guidance of $6.02 to $6.12 and long-term EPS and dividend growth of 7% to 9%. The board declared a quarterly dividend of $0.8950 per share, payable Sept. 1, 2026.
State-level detail shows how rate design can soften the household hit. In September 2026, New Jersey American Water announced a Board of Public Utilities decision approving about $68 million of additional annual revenue to support more than $1.4 billion of system upgrades. The average residential water customer using about 5,700 gallons saw roughly $4 more per month on water and about $4 more on wastewater, while an eligible-customer PFAS credit of $9.88 per month for 12 months offsets part of the increase.
Essential Utilities: Aqua water, Peoples gas, and a $1.7 billion rebuild
Essential Utilities, which operates Aqua water and wastewater systems and Peoples natural gas, serves about 5.5 million people across nine states. Second-quarter 2026 GAAP earnings were $0.37 per share, or $0.38 adjusted excluding merger costs. Quarterly revenues were $530.9 million, up 3% from $514.9 million a year earlier, with the water segment at $357.5 million, up 7.6%. First-half revenues reached $1,392.6 million, up 7.2%.
First-half infrastructure investment was $662.2 million, and the company said it was on track for $1.7 billion of investment in 2026. Year-to-date 2026 water rate awards and surcharges totaled $43.9 million annualized across Pennsylvania, Illinois, Ohio, North Carolina and Indiana, with another $12.7 million of gas awards in Kentucky and Pennsylvania. Pending water and wastewater cases and surcharges still totaled about $79.7 million annualized across Texas, Virginia, Illinois, Indiana and New Jersey, plus a pending Pennsylvania gas rate case requesting $163.2 million.
Management affirmed a multiyear EPS compound annual growth rate of 5% to 7% through 2027, measured from adjusted 2024 EPS of $1.97. The quarterly dividend rose 5.25% to $0.3606. Essential said it had signed acquisition deals of about $282 million covering more than 200,000 equivalent dwelling units, including the roughly $276.5 million DELCORA wastewater transaction for about 198,000 EDUs, and was actively pursuing about 400,000 additional customers.
The American Water and Essential combination
The two companies are also on a merger path that would reshape the regulated water map. American Water's second-quarter update said three states had approved the combination with Essential, a settlement in principle was in place in Texas, and closing was expected in the first quarter of 2027. Essential separately listed Virginia approval on June 22, Ohio on May 14, and Kentucky approval, plus roughly 95% shareholder support for the deal, with the same Q1 2027 close target.
For equity investors, a completed combination would create a larger regulated platform with more rate jurisdictions, a bigger capital plan, and a longer runway of authorized returns if regulators continue to support infrastructure recovery. Integration risk, merger costs and remaining state approvals are the near-term watch items. Until closing, each company still reports on its own capital and rate-case calendar.
What this means for investors
Regulated water utilities are not growth technology stocks. Allowed returns are set in rate cases, volume growth is modest, and weather can move short-term sales. What they offer patient shareholders is visibility: when a utility spends $1.7 billion or $3.7 billion a year on pipes, plants and treatment, that capital usually enters rate base over time, and authorized revenues step up after regulators review the spend.
American Water's affirmed 7% to 9% long-term EPS and dividend growth target, and Essential's 5% to 7% EPS CAGR through 2027, are the kind of multi-year frameworks income-oriented portfolios use when sizing a utility sleeve. Dividend increases, like Essential's 5.25% raise to $0.3606 a quarter and American Water's $0.8950 quarterly declaration, matter more to that audience than any single day's trading range.
Risks are real. Rate-case outcomes can be less constructive than filed requests. Construction inflation can pressure returns until the next case. PFAS and other treatment mandates raise near-term costs before full recovery. Merger closing can slip if a key state delays.
What to watch next is straightforward. First, do authorized revenues keep catching up to capital plans, or do pending requests stall? Second, do 2026 full-year capital totals land near American Water's $3.7 billion plan and Essential's $1.7 billion plan? Third, do remaining Essential merger approvals stay on a path to a first-quarter 2027 close?
What it means for your household
Most households cannot opt out of the water utility the way they can cancel a streaming app. When citywide or statewide rates rise 5% in a year, the bill lands whether usage was flat or not. That is why Bluefield's finding that bills have outpaced inflation for years lands as a budget story as much as an investor story.
Practical steps are limited but useful. Check whether your utility offers budget billing or senior and low-income assistance. Ask whether a temporary credit, like New Jersey's PFAS offset, applies to your account. Fix leaks promptly. If you own investment property, underwrite water and sewer escalators the same way you already underwrite property tax and insurance.
For retirement-age households that also own utility stocks or funds, the dual exposure is worth naming. Higher bills are a cash outflow. Dividend growth from regulated water holdings can be a partial offset inside a diversified portfolio, but only if position size fits your risk tolerance.
The bottom line: U.S. water and sewer rates are in a multi-year climb driven by replacement of aging pipes, treatment rules and higher operating costs, and the largest investor-owned utilities are funding that rebuild through rate cases, surcharges and a planned 2027 combination of American Water and Essential. Households will keep paying more for the service. Patient investors who understand regulation can own the cash flows that fund the pipes.
