The UK is in the grip of its second official heatwave of the year. Last week the Met Office issued a rare red extreme heat warning for parts of England and Wales, with temperatures forecast to hit 38°C and the June record under threat. May had already delivered the hottest May day ever recorded at Kew Gardens. Two record-breaking heatwaves before the summer has properly started is not a freak run of luck. It’s the pattern we’ve been warned about for years, arriving on schedule.

For anyone responsible for a building or an estate, this is more than a weather story. When temperatures climb, water moves to the top of the agenda fast. Supply gets stretched, hosepipe bans and restrictions loom, and disruption follows. Some South East Water customers have already seen issues with supply during this hot spell. Demand spikes at exactly the moment the system is least able to cope, and the organisations that feel it most are the ones that assumed water would always be there.

Here’s the uncomfortable truth though. England is genuinely running out of water. The Environment Agency projects a shortfall of around five billion litres a day by 2055 if nothing changes, which is roughly a third of current public supply. Climate change, population growth and ageing infrastructure are all pulling in the same direction. The heatwave outside your window isn’t the problem. It’s a preview of the operating environment every UK organisation is heading into.

A couple of water saving products is not a strategy

This is where a lot of well-intentioned organisations come unstuck. Someone fits a few waterless urinals, swaps in some low flow taps, ticks the water box in the sustainability report and moves on. The kit gets pointed to whenever water comes up. Job done.

Except it isn’t. A handful of products is a good start, but it is not a strategy, and treating it as one creates a false sense of security. A genuine water management strategy looks across your entire estate and keeps asking three questions everywhere water touches the business. Where are we using more than we need? Where are we losing it without realising? And where could we be capturing and reusing it instead of sending it straight to the drain?

A couple of installs don’t answer those questions at any meaningful scale. They treat a symptom in one corner of one building and leave the wider system untouched. The opportunity, and the risk, sits across the whole estate.

If you haven’t started yet, start in the washroom

If your organisation hasn’t done anything at all on water yet, the washroom is the right place to begin. It’s typically one of the most water-intensive areas of any building, and it’s where the savings are easiest to capture quickly with proven, low-disruption technology.

Waterless urinals are the obvious first move. A single URIMAT waterless urinal can save up to 100,000 litres of water a year, and when you multiply that across multiple washrooms and multiple sites the numbers get serious. There’s no flush water, which means lower water bills, lower carbon and, maintained correctly, no odour.

Low flow and sensor taps are the next layer. They cut the volume used at every handwash, improve hygiene through touch-free operation and stop taps being left running. Showers are another heavy consumer, particularly in gyms, hotels, universities and leisure sites, and shower sensors that nudge users towards shorter showers can take a real bite out of both water and energy bills.

If you’ve not yet made these changes, this is your starting point. Get the basics of the washroom right and you’ll see savings on the water bill, the energy bill and your carbon footprint, often with a payback period that makes the finance team happy.

If you’ve already done the washroom, your work isn’t finished

Here’s the part that catches a lot of organisations out. If you’ve already installed waterless urinals, sensor taps and efficient showers, it’s tempting to consider water dealt with. It isn’t. You’ve completed the first chapter, not the book. The biggest opportunities to use less, waste less and reuse more sit beyond the washroom door, and most estates have barely looked at them.

Waste less: find the water you’re losing without knowing

Leaks are the quiet killer of any water budget. Up to 20% of toilets leak, and a single leaking toilet can waste up to 275 litres a day, silently, around the clock, often for months before anyone notices. Across a large estate that adds up to an enormous volume of water you’re paying for and never using.

This is where smart water management earns its place. Leak detection systems and sensors monitor your water use continuously, flag anomalies the moment they appear and let you fix problems before they turn into floods or eye-watering bills. You can’t manage what you don’t measure, and most organisations simply aren’t measuring with enough granularity to catch this. A digital water management system also helps you stay on top of your compliance and health and safety obligations, with less manual flushing, fewer manual temperature checks and a proper audit trail. It’s not glamorous, but waste reduction is usually where the fastest, cleanest savings hide.

Reuse more: stop sending usable water down the drain

This is the piece most organisations skip entirely, and it’s where the heatwave argument really bites. Rainwater harvesting captures water from your roofs and hard surfaces and puts it to work for toilet flushing, irrigation, cleaning and process uses, taking a meaningful chunk of demand off the mains. Greywater recycling does a similar job by capturing water from showers and basins, treating it and reusing it on site.

The strategic value goes well beyond the bill. In a summer like this one, water you’ve captured and stored is water you control when the mains is under pressure and restrictions are biting. For sites looking at expansion, reuse also feeds directly into water neutrality, which is fast becoming a de facto planning requirement in water-stressed parts of the country. If you can’t demonstrate a credible plan to offset new demand, you may not get to build at all.

Use less everywhere else

Beyond the washroom, demand hides in catering, cleaning regimes, cooling systems, irrigation and any water-using process your operation runs. Most of these have never been benchmarked against a sensible target, which means there’s almost always headroom once someone actually looks. Even your water bill itself is worth auditing. Many organisations are on the wrong tariff, missing available discounts or quietly overpaying surface water drainage charges they could reduce.

Why this matters to you specifically

For the facilities manager, heatwaves mean demand spikes, supply uncertainty and the real prospect of restrictions affecting how your buildings run. A strategy turns water from a source of nasty surprises into something you actively control, with fewer leaks, fewer call-outs and better visibility across every site.

For the sustainability manager, water is climbing the agenda fast and reporting expectations are rising with it. A pile of disconnected products is hard to evidence and easy to pick holes in. A coordinated strategy with measured outcomes, tied to carbon and water neutrality goals, stands up to scrutiny and tells a far more credible story.

For the finance manager, water is a cost that drifts upward quietly and then jumps when scarcity hits. Business water rates rose by an average of 21% in April 2025 alone. A proper strategy turns an unpredictable, rising line into a managed one, and because cutting water also cuts the energy used to heat and pump it, the savings tend to compound across both bills. The case is strong enough that financing the investment often pays for itself from day one.

Where to start

You don’t have to solve the whole estate in one go. You do have to stop treating a couple of products as the finish line.

Start with a proper water audit. Understand where water is used, wasted and could be reused across every site, get the data, set your benchmark, then build a plan that treats water as the strategic resource it has quietly become. Ecoprod is the first organisation in the UK to offer a fully integrated, end-to-end water design and management service, combining expertise across water policy, reuse, irrigation, greywater and rainwater systems, washroom design and the latest water-saving technology. Whether you’re starting with a single washroom or planning a top-down review of water across your entire estate, that whole-picture view is exactly what a real strategy needs.

The heat will pass. The pressure on water won’t. The organisations that treat this heatwave as the prompt to build a proper strategy, rather than buy one more gadget, will be the ones still in control next summer, and the one after that.
