When Did Water Vending Machines Become a Thing?
When did water vending machines appear in America? Explore their history from a 1908 penny water vendor to the refill machines of the 1970s and 1980s.
You’ve probably seen them hundreds of times.
They sit outside supermarkets, convenience stores and shopping centers—or sometimes stand alone in small roadside kiosks. You bring an empty bottle, usually one, three or five gallons, put in some money, push a button and watch purified water pour into your container.
For many people in California, Arizona and other parts of the American West, water vending machines seem like they’ve simply always been there.
But when did we actually start buying water this way?
The answer takes us back more than a century, although the machines we recognize today didn’t really arrive until the 1970s.
The Water Vending Machine’s Surprising Ancestor
The story begins in Boston in 1908 with a man named Lawrence Luellen.
Luellen was working on something that sounds surprisingly modern: a machine that would allow someone to pay a penny and receive a clean drink of water in an individual disposable cup.
At the time, public drinking water was often consumed from a communal cup or metal dipper—a practice that increasingly worried public-health officials because of the potential spread of disease.
Luellen developed a paper drinking cup along with what became known as the Luellen Cup & Water Vendor. The porcelain machine contained water, ice, disposable cups and a place for discarded cups.
For one penny, a customer could get a drink of cold water in a fresh cup.
Historical records at Lafayette College’s Hugh Moore Dixie Cup Company Collection show that Luellen completed work on the vending apparatus in early 1908. His company, the American Water Supply Company of New England, was incorporated on April 4 of that year.
There was just one problem.
The complete water machine was expensive to manufacture.
The company eventually concentrated on selling the disposable cups and cup dispensers instead. Those cups ultimately evolved into one of America’s most recognizable household products—the Dixie Cup.
So although Luellen’s machine wasn’t the five-gallon refill station we know today, the basic idea was already there:
Put money into a machine and receive drinking water.
The Modern Water Vending Machine Arrives
The next major chapter didn’t occur until roughly 65 years later.
According to histories of the water-vending industry, the first practical machines designed to sell purified water in bulk appeared during the mid-1970s.
These were fundamentally different from Luellen’s machine.
Instead of giving customers a cup of water, the new machines treated water—typically municipal tap water—and allowed customers to fill their own reusable containers.
And we have unusually strong evidence that these machines were operating by 1976.
On July 26, 1976, the U.S. Environmental Protection Agency issued a memorandum specifically addressing the regulatory status of water vending machines.
The EPA described machines that filtered and disinfected water with ultraviolet light and then dispensed the treated water into a customer’s own container using a coin-operated mechanism.
In other words, by the summer of 1976, the basic water-refill machine many of us recognize today was already operating in the United States.
Why the 1970s?
The timing wasn’t accidental.
Americans had become increasingly concerned about pollution and drinking-water quality during the 1960s and 1970s.
Congress passed the Safe Drinking Water Act in 1974, establishing a federal framework for protecting public drinking-water supplies. National drinking-water regulations followed during the decade.
Meanwhile, technologies such as filtration, activated carbon treatment, ultraviolet disinfection and eventually reverse osmosis made it practical to build relatively compact systems capable of treating municipal water at the point where it was sold.
The result was a new business opportunity:
Instead of transporting thousands of bottles of water to a store, a vending company could connect a machine to the local water supply, purify that water on site and sell it by the gallon.
Customers supplied the bottle.
California Helps Turn It Into a Business
California became one of the industry’s most important early markets.
One company that would eventually become a major player was founded by Robert G. Miller.
In 1983, Miller established Bottle Water Vending Inc., the predecessor of Glacier Water Services.
The company manufactured water vending machines and placed many of them outside supermarkets. Customers brought their own containers, while participating stores often sold reusable plastic jugs nearby.
The machines treated municipal water using combinations of filtration, reverse osmosis, carbon treatment and ultraviolet sterilization.
The idea caught on quickly.
In 1984, the company expanded from California into Arizona.
Nevada followed in 1986.
By 1987, the company reportedly had nearly 900 water vending machines operating.
Texas and Florida followed in 1988.
The familiar supermarket water-refill station was becoming a significant business.
Then Came the Drive-Up Water Kiosk
Another variation appeared at almost exactly the same time.
In 1984, Lani and Don Dolifka developed what became Watermill Express in Colorado.
Their idea was an automated stand-alone purification kiosk capable of taking municipal water, processing it through multiple purification stages and selling the finished drinking water directly to customers.
Instead of walking into a supermarket, customers could pull up to the kiosk with their bottles.
Later Watermill Express systems were designed to accommodate reusable containers ranging from one to five gallons, using treatment processes including sediment filtration, activated carbon, reverse osmosis, ultraviolet disinfection and ozone treatment.
That basic concept remains familiar today.
Why Five-Gallon Bottles?
The five-gallon container was already well established through traditional bottled-water delivery services.
But refill vending changed the economics.
Instead of purchasing another filled bottle—or waiting for a delivery—a customer could keep the same container and refill it repeatedly.
That eliminated much of the packaging and transportation involved with conventional bottled water.
It also made purified drinking water relatively inexpensive.
Bring the jug.
Buy the water.
Take the same jug home.
Bring it back when it’s empty.
More than four decades later, that’s still essentially how the system works.
So Who Invented the Modern Water Vending Machine?
That’s where the story gets complicated.
There doesn’t appear to be a single universally recognized inventor of the modern bulk purified-water vending machine.
Lawrence Luellen developed an important early coin-operated water vending concept in 1908, but his machine dispensed an individual drink and disposable cup—not gallons of purified water into a customer’s reusable bottle.
The modern bulk-water machine emerged much later, apparently during the mid-1970s, as water-treatment technology and consumer concern about drinking-water quality converged.
By 1976, the EPA was already dealing with the regulatory implications of machines that treated municipal water and sold it through coin-operated dispensers into customers’ own containers.
Entrepreneurs and companies then refined and expanded the idea during the 1980s.
From a Penny Cup to Five Gallons at a Time
The evolution is remarkable.
1908: Put in a penny and receive a cup of cold water.
Mid-1970s: Machines begin treating municipal water and selling purified water in bulk.
1976: The EPA documents coin-operated machines dispensing treated water into customers’ containers.
1983: Bottle Water Vending, the predecessor of Glacier Water Services, begins operations in California.
1984: Glacier’s predecessor expands into Arizona, while Watermill Express develops its automated purification kiosk in Colorado.
Late 1980s and beyond: Water refill machines become increasingly familiar outside supermarkets and at stand-alone locations throughout the United States.
Today, paying a few coins—or tapping a card—and filling a five-gallon jug might seem thoroughly ordinary.
But the machine sitting outside your neighborhood supermarket represents more than a century of evolution in how Americans buy something that once seemed almost unimaginable to sell from a vending machine:
a drink of water.

Octavia E. Butler: The Black Woman Who Helped Change Science Fiction
Discover how Octavia E. Butler transformed science fiction, explored Black identity, and helped shape Afrofuturism through her groundbreaking novels.
Forgotten Genius Friday | The Knowledge | STM Daily News
Octavia E. Butler: The Woman Who Reimagined the Future
When we think about science fiction, we often picture spaceships, robots, alien civilizations, and futuristic technology. But what happens when science fiction becomes a way to explore racism, inequality, human survival, and the consequences of our choices?
That is exactly what Octavia E. Butler brought to the genre.
Long before Afrofuturism became a widely recognized cultural movement, Butler was creating extraordinary stories that placed Black characters—especially Black women—at the center of imagined futures.
Her work challenged conventional ideas about who could be a hero, whose experiences mattered, and what science fiction could accomplish.
A Young Girl With a Powerful Imagination
Octavia Estelle Butler was born on June 22, 1947, in Pasadena, California.
Raised primarily by her mother and grandmother after her father’s death, Butler grew up shy and found comfort in books and storytelling.
Her mother worked as a domestic employee, and Butler sometimes accompanied her to work. Those experiences exposed her to the racial and economic inequalities that would later influence her fiction.
As a child, Butler loved science fiction, but she noticed something missing: people who looked like her.
Rather than accepting that absence, she began creating stories of her own.
She would eventually become one of the most influential writers in speculative fiction.
Breaking Barriers in Science Fiction
During the 1970s, mainstream American science fiction was largely associated with white male writers and protagonists.
Butler entered that literary world with a different perspective.
Her first published novel, Patternmaster, appeared in 1976. It introduced readers to a world shaped by extraordinary mental abilities, social hierarchies, and struggles for power.
Butler continued developing complex stories that explored humanity’s relationship with authority, identity, biology, and survival.
In 1979, she published one of her best-known novels, Kindred.
The book follows Dana, a Black woman living in 1970s California who is repeatedly transported back to a Maryland plantation before the Civil War.
Through Dana’s experiences, Butler forced readers to confront the brutality of American slavery and its continuing influence on the present.
Rather than treating history as something safely confined to the past, Kindred makes that history immediate and deeply personal.
Imagining the Future—and Warning Us About It
In 1993, Butler published Parable of the Sower, a novel set in a collapsing American society struggling with economic inequality, environmental destruction, violence, and weakened institutions.
Its central character, Lauren Olamina, is a young Black woman who develops a philosophy called Earthseed while searching for a way to survive and build a community.
The novel takes place beginning in 2024, making its imagined future particularly striking to modern readers.
Butler followed it with Parable of the Talents in 1998, continuing her examination of social instability, religious extremism, authoritarianism, and the struggle to create a better future.
Her novels were not literal predictions. They were works of speculative fiction that used recognizable social trends to ask difficult questions about where humanity might be headed.
Octavia Butler and Afrofuturism
Afrofuturism brings together African and African diasporic experiences with science fiction, technology, history, mythology, and imaginative visions of the future.
While artists such as Sun Ra and George Clinton explored cosmic identity through music, performance, and futuristic imagery, Butler used literature to investigate power, history, and humanity’s possible futures.
Her novels frequently placed Black women in situations where they had to navigate extraordinary challenges and reshape the societies around them.
Butler’s work is widely discussed within Afrofuturist scholarship, although her literary contributions also extend beyond any single cultural label.
She demonstrated that Black people did not have to remain secondary characters in someone else’s vision of the future.
They could be the architects of entirely new worlds.
Recognition and a Lasting Legacy
Butler received some of science fiction’s most significant honors, including Hugo and Nebula Awards.
In 1995, she became the first science-fiction writer to receive a MacArthur Fellowship, often called a genius grant.
Her work also included the Xenogenesis trilogy, later collected as Lilith’s Brood, which explored humanity’s encounter with an extraterrestrial species and raised questions about consent, adaptation, identity, and survival.
Butler died on February 24, 2006, at age 58.
Yet her influence has continued to grow.
Her novels are studied in classrooms, discussed by scholars, and embraced by new generations of readers and creators interested in science fiction, social justice, and Afrofuturism.
A Genius Who Made Us Think Differently About Tomorrow
Octavia E. Butler was more than a science-fiction author.
She was a visionary storyteller who understood that imagining the future also meant examining the past and questioning the present.
Her stories asked readers to consider how power operates, how communities survive, and how human beings might change.
And perhaps her greatest contribution was demonstrating that the future belongs in the imagination of everyone.
Why Octavia E. Butler Belongs in Forgotten Genius Friday
At STM Daily News, our Forgotten Genius Friday series celebrates extraordinary individuals whose ideas, innovations, and accomplishments helped shape our world, even if their stories aren’t widely known. Octavia E. Butler fits that mission perfectly. Although she received prestigious literary awards and recognition during her lifetime, her influence extends far beyond science fiction. Like the inventors, scientists, and trailblazers we’ve featured in this series, Butler challenged barriers, defied expectations, and opened doors for future generations. Through her imagination, she helped redefine who could tell stories about humanity’s future—and who could be at the center of those stories. Her inclusion in Forgotten Genius Friday reminds us that genius isn’t limited to laboratories and inventions. Sometimes, it begins with a pen, a powerful imagination, and the courage to envision a different world.

Food Truths
Soul Food Has African Roots—and a Distinct Black American History
Soul food connects African heritage with generations of Black American creativity and community. Here’s why shared roots and a distinct cultural identity both deserve recognition.
Last Updated on October 15, 2026 by Daily News Staff
Shared ancestry connects the African diaspora. It also makes understanding each community’s food traditions worth the effort.
A debate over who can claim soul food raises a question larger than any social media argument: When does a shared cultural inheritance become a distinct tradition?
People across Africa and the African diaspora have foods that evoke home, family, comfort, and belonging. Recognizing that connection is valuable. But using “soul food” as a general description of comforting food is different from identifying the cuisine historically known by that name.
Soul food is a distinctly African American culinary tradition with African roots, shaped by generations of Black life in the United States. Recognizing its American development does not erase Africa. Recognizing Africa should not erase what Black Americans created.
African Roots, American Development
Enslaved Africans arrived with agricultural knowledge, cooking skills, and food traditions. They adapted those traditions to unfamiliar surroundings and unequal access to food, drawing on available ingredients and encounters with Indigenous and European foodways.
Okra, black-eyed peas, and vegetable-centered cooking offer important connections to African traditions. Corn and cornmeal reflect Indigenous American agriculture. These ingredients and influences became part of an evolving food culture rather than remaining unchanged copies of dishes from another continent. [1]
The distinction is between ancestry and development. A cuisine can descend from older traditions and acquire its own identity through the experiences of the people who preserve and transform it.
More Than a Story About Scraps
Slavery and deprivation belong in this history. Enslaved people supplemented restricted food supplies through gardening and other means, and used small amounts of meat to season vegetables. But telling the entire story as “making something out of scraps” understates their knowledge and creativity.
Black food history also includes seafood work, farming, skilled cooking, and enterprise. The Smithsonian’s account of Black foodways, for example, documents African Americans’ extensive involvement in harvesting, processing, and selling oysters. [2]
These were people with expertise. Their contributions deserve recognition as culinary work and cultural creation.
Why the Name Matters
The food traditions are older than the widespread use of the name “soul food.” The term became prominent during the 1960s, amid movements asserting Black identity and cultural pride. Smithsonian histories describe the soul food movement as celebrating foods that mainstream America had often disparaged. [3]
That context gives the name meaning beyond a meal that tastes good or brings comfort.
For some families, a pot of greens or a pan of cornbread carries memories of relatives, church dinners, holidays, and recipes learned by watching someone cook. Calling those foods “soul food” places them within a particular cultural story.
Southern Roots Traveled
Soul food also developed beyond the South. During the Great Migration, Black Americans carried Southern food traditions into new cities and neighborhoods, preserving familiar dishes while adapting their cooking. Smithsonian programming connects that movement directly to soul food’s development. [4]
That helps explain how a cuisine rooted in the South became part of Black community life across the country.
It also makes geography an imperfect test of authenticity. Soul food cooked in London can still be African American soul food. A cuisine’s cultural origins do not change simply because someone prepares it elsewhere.
Shared Heritage Does Not Mean Identical Cultures
Africa is a continent of many food traditions. The diaspora is similarly diverse. African American, Afro-Caribbean, Afro-Latin American, and Black British identities encompass different histories and relationships to food.
Someone may use “soul food” figuratively to describe a cherished family dish. That emotional use is understandable. The difficulty arises when it becomes a historical claim that all Black cuisines are versions of the same named tradition.
Shared ingredients and ancestry establish connections; they do not make distinct cuisines interchangeable.
A useful conversation would ask which dishes are related, what techniques survived, and how different communities adapted them. That approach gives people more history to appreciate.
Respect Through Recognition
Defending soul food’s African American identity need not become an attack on Africans, Caribbean people, or Black Britons. Equally, celebrating connections across the diaspora should include respect for Black Americans’ particular contributions.
Anyone can cook, enjoy, study, and share soul food. Cultural recognition does not require closing the kitchen door. It requires crediting the people and history behind the cuisine.
Soul food’s African roots and African American identity belong in the same sentence. Both deserve to be remembered.

Where Does Federal Money Go? The Biggest Costs Behind the Budget
Where does federal money go? Part two of our National Debt Explained series examines the biggest expenses in the 2025 budget and how spending connects to government borrowing.
Last Updated on October 13, 2026 by Daily News Staff
The Knowledge | National Debt Explained, Part 2
When discussing debt, ask: Who borrowed the money? That question helps distinguish a family’s finances from the federal budget. Our first episode explained why your credit card balance is separate from the national debt. Now comes the next question: What does the federal government spend money on?
Much of it pays for retirement benefits, health coverage, national defense, public services, and interest on previous borrowing.
Social Security was the largest individual program in fiscal year 2025, costing approximately $1.6 trillion. But combine the major health care programs—including Medicare, Medicaid, and health insurance subsidies—and their spending reached about $1.8 trillion, exceeding Social Security alone. cbo.gov
The figures below cover October 1, 2024, through September 30, 2025.Major expense FY 2025 spending What it supports Social Security About $1.6 trillion Retirement, survivor, and disability benefits Medicare, net $988 billion Health coverage for older adults and certain people with disabilities Net interest $970 billion Cost of servicing publicly held federal debt, after subtracting interest income Discretionary defense $893 billion Military personnel, operations, equipment, and research Medicaid $668 billion Federal contribution toward health coverage and care for eligible people
These are selected expenses, not the entire budget. Medicare spending is shown after premiums and other offsetting receipts. The combined health care total already includes Medicare and Medicaid, so it should not be added to those rows. cbo.gov
The government also supports veterans’ health care, transportation, education, housing assistance, courts, law enforcement, scientific research, disaster response, and environmental protection. Nondefense discretionary spending totaled approximately $980 billion in 2025, covering many of these services. Some funding for these areas falls elsewhere in the budget. cbo.gov
Federal spending falls into three broad groups:
- Mandatory spending: Payments governed by existing eligibility rules and benefit formulas, including Social Security and major health programs.
- Discretionary spending: Funding lawmakers control through appropriations legislation, including most defense spending and many public services.
- Net interest: The expense of servicing publicly held federal debt, minus government interest income. cbo.gov
Interest deserves attention because it pays for borrowing already undertaken. In 2025, net interest exceeded discretionary defense spending. Congressional Budget Office
A program’s cost does not automatically translate into an equal increase in national debt. Taxes and other receipts finance much of federal spending. Social Security and Medicare’s hospital insurance program receive dedicated payroll taxes, while Medicare also collects premiums.
In 2025, federal spending totaled approximately $7 trillion, compared with $5.2 trillion in revenue. The roughly $1.8 trillion shortfall was the deficit, requiring borrowing. Understanding national debt therefore means examining both what government spends and what it collects. cbo.gov
