Walk through one city and a free drink may be a short stroll away. In another, a person without a bottle or money has to search for a café, a library or an open public building. The difference is seldom explained by whether the local tap water is drinkable. A street fountain is a small piece of infrastructure that needs a water connection, a suitable site, permission, cleaning, repairs and a body willing to pay for those tasks year after year.
London offers a useful example of how deliberate those arrangements must be. The Mayor's programme with Thames Water has installed a network of more than 100 fountains in busy, accessible places. The stated aims include free access to tap water and fewer single-use plastic bottles. Thames Water owns the installed units and has committed to maintaining and cleaning them for at least 25 years.¹
A drinking fountain is a service, not just an object
A fountain can look like a simple fixture on a pavement. Installing one may require connecting to a water main and drainage, dealing with underground obstructions, reinstating the surface and getting approval from the landowner or highway authority. London City Hall said the average combined unit and installation cost for its first six installations was between £8,500 and £9,500, with site-specific conditions affecting the price. That is an early programme figure, not a general price tag for every city or design.²
Once it is installed, someone must clean it, inspect it and fix parts that fail. In a 2019 London Assembly answer, the Mayor's office estimated cleaning and maintenance at £6,000 per fountain per year for that programme and cited long-term costs as one reason older fountains had fallen into disrepair and been removed. The precise bill will vary elsewhere, but the lesson travels: a one-off capital grant will not keep water flowing if no organisation owns the daily work.²
There are less visible decisions too. A fountain needs to be located where people can find and use it without blocking movement. The London public-realm guidance calls for potable-water fountains to be easy to clean, physically and visually accessible, and convenient to the wider public realm. A unit behind a locked gate, out of service for months or too awkward for some users may appear on a map while doing little to improve practical access.³
Why policy makes the map uneven
Municipalities can provide fountains directly, require them in certain developments, fund them through parks budgets or form partnerships with water utilities and landowners. They can also leave provision to the decisions of individual sites. Those choices accumulate over decades into a patchwork.
A study of US municipalities illustrates the gap between supporting the idea and building it into planning rules. More than half of surveyed municipalities reported plans or budget provisions for free drinking water in outdoor areas or parks, but fewer than one in ten reported zoning or development policies requiring or encouraging drinking fountains in publicly accessible outdoor places. Larger municipalities were more likely than smaller ones to have several types of water-access policy. The survey concerns US municipalities in 2014; it does not rank today's cities by working fountains, but it shows how variable the policy machinery can be.⁴
The London partnership solved one institutional problem by assigning ownership and maintenance to the water company while the city and site owners supported installation. Its application process still required suitable locations and local commitments. The programme's own planning documents describe the need to manage connection, permission and maintenance issues.¹,⁵
A city that installs fountains only when a park is rebuilt may gradually acquire a sparse network. A city that treats them as part of a wider public-water service, budgets for repairs and makes sites easy to approve can develop a denser one. This is an inference from the different policy and programme models, not a claim that one factor explains every city's history.¹,⁴,⁵
The public purpose has changed
Public water was once closely associated with sanitation and access to safe drinking water. Victorian London's fountain movement belongs to that history. Today the case often includes convenience, health, access to public space and reducing disposable packaging.¹,⁶ The emphasis varies with local conditions; a fountain may be especially valuable on a hot walking route or in a place where buying a drink is the only obvious alternative.
The environmental case also needs careful wording. A refill point can make it easier to use a reusable bottle instead of buying a single-use one, and London's programme explicitly aims to change that behaviour. But a fountain's presence alone does not prove how many bottles it prevents. Actual use depends on whether it works, where it stands and whether people trust it.¹
Trust and upkeep are linked. A dry, damaged or visibly dirty fountain sends a stronger message than a campaign poster. In a 2026 London Assembly response, City Hall listed failures ranging from parts and vandalism to problems with mains supply; the maintenance responsibility remained with Thames Water. This does not mean every fountain is unreliable. It shows why keeping an accurate, usable network is an ongoing operation rather than a completed construction project.⁷
What would count as good provision?
Counting fixtures is a beginning, but it is not a complete measure. A useful assessment would ask how many are actually working, where they sit relative to busy routes and underserved areas, whether people can use them at different times of day, and how promptly faults are fixed. That is a practical way to judge the service, rather than treating every dot on a map as equal.
Picture two neighbourhoods, each with ten listed fountains. In one, all ten are on public routes, clearly signed and maintained. In the other, several are inside facilities with limited opening hours and others are broken. The raw total is the same; the opportunity to get a drink is not. This comparison explains why maintenance and access belong in the same conversation as installation.
Abundant public fountains are usually the result of decisions that make provision routine and give somebody clear responsibility for keeping it usable. Scarcity may reflect installation cost, competing priorities, fragmented land ownership or weak maintenance arrangements. The presence of safe tap water is a necessary starting point, but a convenient free drink in the street requires a city to build and sustain the last few metres of access.
