The Real Reasons Why Venues Switch to Filtered Water, and Why They Stay
By Nick Hargrave, CEO, EcoPure Waters
EcoPure Waters was founded almost 35 years ago on a simple pitch: give venues a better, and much cheaper, way to serve filtered water than trucking single-use bottles in and out every day. That is still how most conversations start. Cost and carbon are what get a venue to the table.
But read what our clients say once their systems are running, and it tells a different story from our own marketing.
What we lead with
Our headline numbers are the ones you would expect. Across our client base, venues save a combined 16 million single-use bottles a year and more than 4,500 tonnes of CO2, with the cost per bottle falling to 19p at scale. The full breakdown is in our EcoPure Effect 2026 report.
They match the briefs we receive. When EC Catering Partners, who cater at Reading’s stadium, came to us, the brief had two lines: reduce cost, and reduce the carbon impact of single-use bottles. The result was an estimated £19,000 a year in savings, a 78% saving per bottle, and more than 26,000 single-use bottles removed from service every year, around 8 tonnes of CO2.
That is the pitch working exactly as intended.
What clients actually say
Now look at the nine quotes in that same report.
Grantley Hall saves 160,000+ bottles and £119,000 a year. Its general manager’s comment is mostly about something else: that working with us has allowed the hotel to maintain an exceptional level of quality for its guests, with reducing its reliance on glass recycling as the second half of the sentence. The operations manager at Stowe School talks about quality of service in a partner. Harper Weddings says its couples expect everything to be perfect on their special day and water is no exception. Champneys is pleased to serve filtered water in bottles that carry its own brand. The Harwood Arms builds everything around provenance and the seasons, and says the water is no different.
Two more fit the pattern. The procurement coordinator at Signature Senior Lifestyle calls easy access to cold still and sparkling water for residents an absolute must-have, for sustainability and for a premium experience. And EC Catering, whose brief was all about cost and carbon, describes our level of service as second to none.
Only one of the nine, St George’s Hill Golf Club, makes sustainability the whole point. It does appear elsewhere, in the fuller versions of the Grantley Hall and Signature testimonials, but alongside quality and a premium experience rather than instead of them. So this is a matter of emphasis, not exclusivity. None of the quotes as printed in the report mentions price.
Caution is due. These are testimonials we chose to publish, from a small slice of our client base, so treat them as a signal, not a survey. People praising a supplier are also not necessarily describing why they bought. But the pattern is hard to ignore: the numbers get a venue through the door, and quality, service and brand are what it talks about once it’s inside.
Why the gap matters
I would argue this. Savings and sustainability are the reasons to start the conversation, but a venue will only stay with the responsible option if nobody can tell it is a compromise. A guest, a member, a resident or a parent cannot be asked to accept a worse experience in the name of the planet. Neither can the general manager whose name is on the property.
That is what I mean when I say premium and responsible were never a trade-off. It is a condition of the sale. It is also why I am wary of treating sustainability as a feature to bolt on. If the bottle chips, the print fades or the water is forgettable, a venue’s goodwill towards the cause lasts about one service.
It also changes what we build. Printing that does not fade or peel after a season of daily washing. Bottles made to be refilled thousands of times, not replaced every quarter. Filtration that stands up next to any bottled brand on the table. None of these appear in a carbon calculation, and all of them decide whether a venue is still happy in year three.
It is not only a hospitality story
Hospitality is 58% of our client usage, but the rest tells you something too. Education and care homes together account for close to two-thirds of the usage outside hospitality. In those settings the reasons to choose a system look different. Cost predictability matters because budgets are tight and fixed. Duty of care around water quality matters because the people drinking it cannot choose to go elsewhere.
Sustainability still matters in a school or a care home. It is simply not the only argument, and it is rarely the first one.
The part no spreadsheet captures
Numbers prove the case to finance and sustainability teams. They do not pour the water.
What matters is service. That is why a 24-hour fix and a dedicated engineer who knows your site by name are not extras. They are what the venue is actually buying, alongside the filtration. So is a real person at the end of the phone, never a bot.
I cannot prove that this is why so many clients stay and we maintain a 98% client retention rate. What I can say is that the things clients praise are the things we promise, and that is not an accident.
Three questions I would ask any buyer
Will anyone miss someone’s else brand on the bottle? Put your filtered water on a real table in front of real guests, residents or pupils. If the water, the bottle or the service looks like a compromise, the saving will not hold.
Who answers when it fails, and how fast? Ask for the commitment in writing, and ask whether the person who turns up knows your site.
Can the supplier show you real numbers, including the limits? Ours are published. Payback is typically under 12 months and often under six at higher volumes, but it is not universal. Against the cheapest single-use plastic, the report shows it takes around 75 bottles a day to clear 12 months. A supplier who only tells you the good numbers is selling, not advising.
Doing the work, not just the marketing
Sixteen million bottles a year is not an abstract statistic to the general managers and procurement teams we work with. It is the reason they can look a guest, a member, a resident or a parent in the eye and mean it when they say they have done the work on sustainability, not just the marketing.
That only holds if the water is good, the bottle is theirs and the system keeps working. If you are weighing up the switch, model your own numbers with our savings calculator, read more case studies, or talk to us.
FAQ
Why do venues switch to on-site filtered water? The usual starting points are cost and reducing single-use waste. Across our client base, venues save a combined 16 million single-use bottles and more than 4,500 tonnes of CO2 a year. What clients tell us they value afterwards tends to be quality, service and the branded bottle.
Will reusable bottles make the water service feel less premium? Our commitment is filtered still and sparkling water that stands up next to any bottled brand on the table, in bottles that carry the venue’s own logo and are built to be refilled thousands of times. Putting it on a real table is the best test.
How quickly does a system pay for itself? Typically in under 12 months, and often under six at higher volumes. Against glass and premium plastic, payback is within 12 months once usage passes 25 bottles a day. Against the cheapest plastic it takes around 75 bottles a day. The savings calculator models your own numbers.
What happens if something goes wrong? Every client has a 24-hour fix, a dedicated engineer who knows the site, and a real person on the phone. See our troubleshooting guide for common issues.
Is this only for hotels and restaurants? No. Hospitality is 58% of our client usage, and the rest spans education, care homes, clubs and golf clubs, venues and catering, and offices. See our sector pages for how it works in each.
