In most facilities, drinking water systems tend to fade into the background. They’re required by code and expected to work, but they’re rarely revisited or reconsidered. That said, public drinking fixtures have changed more in the last 100 years than most people realize. What started as a response to public health concerns has evolved into today’s bottle filling stations — systems that reflect changing expectations around safety, convenience and sustainability.
For engineers, contractors and facility managers, that evolution is more than a historical footnote. It influences how these systems are designed, where they’re located, how they’re maintained and, ultimately, how they’re used.
BORN FROM CRISIS
The modern drinking fountain was originally a solution to a very real health risk. In the late 1800s, it was common practice for people in workplaces and schools to share a communal cup. Not surprisingly, that created an easy pathway for illness to spread.
While on his rounds as a sanitation inspector for public schools, Luther Haws noticed students drinking water from a shared tin cup. Recognizing the danger, Haws applied his inventiveness to assemble from existing plumbing parts the world’s first drinking faucet in 1906, later receiving patents for the design.
Independently, Halsey W. Taylor, after losing his father to typhoid fever and later witnessing similar health concerns in industrial settings, set out to create a safer alternative. In 1912, his answer took the form of the “Puritan Sanitary Fountain.” Instead of requiring a shared cup, it delivered a stream of water that could be consumed directly.
The concept behind these innovations was simple, but it solved a critical problem. Within a short period, drinking fountains began showing up in schools, factories, offices and other public spaces.
It’s worth noting that the early appeal of these fixtures had little to do with convenience. Their primary value was sanitary access to drinking water. At a time when water quality was a constant concern, the fountain served as a controlled, safer interface between the user and the water supply. For engineers of that era, it was as much a public health solution as it was a plumbing product.
DECADES OF IMPROVEMENT
From there, progress came in increments. As building systems advanced, so did drinking fountains. Cooling capabilities were added — first with ice and eventually with mechanical refrigeration. Units became smaller and easier to integrate into walls and corridors, making them practical for a wider range of building types.
By the mid-20th century, accessibility began shaping design decisions as well. The eventual introduction of ADA requirements resulted in dual height units and clearer access standards, reinforcing the idea that drinking water should be accessible to everyone in a building.
Despite these improvements, the basic experience didn’t change much. Drinking fountains were still designed for quick, direct use — take a drink and move on.
That model began to shift toward the end of the century. As bottled water became more widely available, consumer habits started to change. Even as municipal systems improved, many people chose packaged water over public fixtures. Gradually, fountains became easy to overlook — still required, but no longer central to how people stayed hydrated throughout the day.
IMPACT OF THE BOTTLED WATER BOOM
By the early 2000s, bottled water had reshaped expectations. Hydration was no longer tied to a single location. Instead, people carried water with them, refilling — or more often replacing — their bottle throughout the day.
That shift exposed a gap in the built environment. Traditional drinking fountains weren’t designed to fill containers efficiently, and awkward attempts to do so often reinforced the perception that bottled water was the easier option. Even in buildings with safe, accessible water, many users defaulted to purchasing a bottle instead.
At the same time, awareness of the downsides of single-use plastics began to build. The volume of bottles being produced — and discarded — raised concerns about waste, emissions and long-term environmental impact. Even when recycled, the production of singleuse plastic bottles can require significantly more water than the bottles ultimately contain.
Taken together, those trends created pressure for a different kind of solution — one that would support how people actually consumed water while addressing sustainability concerns.
A TURNING POINT
That shift arrived in 2010 with the introduction of the bottle filling station. Elkay’s ezH2O® helped redefine expectations by focusing on how people were already using water — not by trying to bring them back to traditional fountains.
The concept addressed a few key pain points all at once. It allowed users to refill containers quickly, reduced the need for physical contact and incorporated filtration directly into the unit. Just as importantly, it made refilling visible and easy.
Adoption followed quickly. Early installations spread across schools, airports, health care facilities and office environments. What began as a relatively new idea quickly became a standard feature in hightraffic buildings.
At its core, the appeal came down to a few practical advantages. Faster fills that work for bottles, not just drinking. Touchless operation that improves hygiene. Strategic placement that encourages use. A clear alternative to disposable plastic.
Rather than replacing traditional infrastructure, the bottle filling station reshaped it around modern habits.
REUSABLE BOTTLES
The rise of bottle filling stations goes hand in hand with the widespread use of reusable bottles. Over time, that shift has fundamentally changed how people interact with buildings.
Instead of stumbling across a fountain, users now look for dedicated refill points. In places like airports, schools and offices, bottle filling stations are increasingly viewed as expected amenities rather than upgrades.
For the design and engineering community, that carries implications. Hydration points are no longer just about meeting code minimums — they play a visible role in occupant experience. Location, flow rate and the ability to serve multiple users efficiently all come into play.
FILTRATION BECOMES THE EXPECTATION
As refill behavior increased, so did attention to water quality. Concerns about contaminants — including lead, PFAS and microplastics — have become part of the broader conversation around drinking water.
As a result, filtration has largely moved from a differentiator to a baseline feature. Today’s bottle filling stations are expected to do more than dispense water: they’re expected to improve it.
Modern systems are commonly designed to reduce heavy metals and particulates, improve taste and odor, address emerging contaminants where possible and provide visible indicators of filter status.
From a specification standpoint, including filtration is often no longer optional. It’s a core requirement, shaped by both regulation and user perception.
MAINTENANCE AND LIFECYCLE CONSIDERATIONS
Of course, incorporating filtration introduces new responsibilities — particularly around maintenance. Filters need to be changed on a regular schedule to ensure performance doesn’t degrade over time.
How often that happens depends on several variables, including water conditions, usage levels and the specific system being used. In busy locations, service intervals can be relatively short.
That’s why serviceability has become a key focus in newer designs. Features such as quick-change filters, accessible mounting locations and clear status indicators all help reduce the time and effort required for routine maintenance. Increasing the capacity of the filter cartridge itself allows for fewer maintenance trips overall.
For engineers and facility teams, this shifts the specification conversation. It’s no longer just about initial performance. Ease of service and long-term operating efficiency play an equally important role.
A VISIBLE IMPACT ON SUSTAINABILITY
One of the reasons bottle filling stations have gained traction is their direct connection to sustainability goals. According to Elkay, its bottle filling stations avoided the use of more than 20 billion single-use plastic bottles in 2025, representing more than 520,000 tons of plastic. Encouraging the use of reusable bottles can significantly reduce reliance on disposable plastic.
Many units now include counters that display how many bottles have been avoided, giving users a tangible sense of impact. That kind of feedback reinforces behavior while also supporting broader environmental initiatives.
At the same time, it’s important to recognize that bottled water hasn’t disappeared. The market is still substantial. What bottle filling stations offer is a practical way to reduce dependence on single-use options — especially in controlled, high-use environments.
WHAT COMES NEXT
Looking ahead, bottle filling stations are likely to continue evolving in a few key areas.
Water Quality: As standards change, filtration technologies will continue to adapt, particularly around emerging contaminants.
Connectivity: Monitoring systems may provide better insight into usage patterns and maintenance needs, enabling more proactive service.
Efficiency: Longer-lasting filters and simpler maintenance processes will help reduce operating costs. Integration: Hydration systems will increasingly be treated as part of the overall building experience, not just a code requirement.
A BROADER CHANGE
From the earliest sanitary fountains to today’s bottle filling stations, the trajectory of this category closely mirrors larger shifts in public health, behavior and environmental awareness.
For those responsible for designing and maintaining building systems, the takeaway is straightforward. Drinking water infrastructure is no longer passive. It needs to perform, adapt and meet user expectations in ways that go beyond minimum compliance.
In many respects, today’s bottle filling stations return to the original goal: providing safe, accessible water. The difference is in how that goal is defined—cleaner, easier to access and aligned with how people actually consume water today.
The result is a system that does more than meet a requirement. It supports healthier habits, reduces waste and plays a visible role in the modern built environment.
