Water is becoming harder to ignore.
As the UK emerges from another period of extreme heat, a new national campaign is calling on the public to reduce daily water use and treat water as a precious resource, not an unlimited one.
The Let’s Save Water campaign is asking people in England to save 28 litres of water per person, per day, described as “about a kitchen sink full”. In Wales, the target is 38 litres per person, per day, or around three buckets. The campaign states: “Saving 28 litres in England or 38 litres in Wales per person, per day will ensure there’s enough water for generations to come.” - Source: Let’s Save Water campaign.
This is a simple message with a much bigger meaning. Water efficiency is no longer just a household issue, a summer issue, or something that only matters during restrictions. It is becoming a national resilience issue.
The UK’s water challenge is becoming more urgent
The Environment Agency has warned that water efficiency must become a national priority. In its recent update, it stated that average daily water use in England remains around 136.5 litres per person per day and highlighted the legal target to reduce public water supply use per person by 20% by 31 March 2038.
That target matters because the UK is facing a combination of rising demand, population growth, ageing infrastructure, climate pressures and changing weather patterns. Periods of heat and drought place more strain on water supplies, while everyday consumption continues largely unnoticed.
Ofwat has also highlighted the scale of daily water use, stating that “we each use about 150 litres every day” and that “climate change could mean that less water will be available in the future”.
The message is clear: reducing demand is not optional. It is part of protecting future water availability.
Awareness alone is not enough
Campaigns such as Let’s Save Water are important because they help bring water use into everyday conversation. They encourage people to take practical steps such as taking shorter showers, fixing dripping taps, using appliances efficiently and avoiding unnecessary outdoor water use.
But awareness alone only goes so far.
One of the biggest challenges is that many people do not know how much water they actually use. Water UK research found that 94% of the public underestimate how much water they use per day. In a later survey, Water UK reported that people in England and Wales believed their household used just 62 litres of water per day, while the actual average household figure was 323 litres per day.
Water UK described this as a major gap between perception and reality. In simple terms, many people think they are using far less water than they really are.
This creates a practical problem. If households, businesses and facilities teams do not have clear visibility of water use, it becomes difficult to understand consumption, identify waste or know which actions will make the biggest difference.
Water use is often invisible until something goes wrong
Unlike electricity or gas, water use is often less visible. It flows through taps, showers, toilets, appliances, heating systems, washrooms, commercial kitchens, plant rooms and building services with very little real-time feedback.
For households, that can mean wasteful habits go unnoticed.
For businesses and commercial buildings, the problem can be much larger. Water may be used across multiple floors, tenants, facilities, plant areas and operational processes. Usage can change depending on occupancy, cleaning schedules, working patterns, visitor numbers, seasonal demand and building type.
Without live monitoring, many organisations are left relying on periodic bills, manual meter reads or assumptions. By the time an issue appears on a bill, the water may already have been wasted.
This is particularly important when it comes to leaks. A leak does not need to be dramatic to be costly. Small, continuous losses can add up over time. In larger estates, even minor inefficiencies across multiple buildings can result in significant avoidable consumption.
Smart water monitoring turns awareness into action
This is where smart water monitoring has a vital role to play.
Real-time water data helps turn an invisible resource into something measurable. Instead of relying on estimates, assumptions or delayed bills, households, businesses and facilities teams can see how water is being used, identify unusual patterns and respond earlier.
Smart monitoring can support water efficiency by helping users:
Understand normal consumption patterns
Spot unexpected spikes in usage
Identify continuous flow that may indicate a leak
Compare water use across buildings or areas
Measure whether water-saving actions are working
Support sustainability and ESG reporting
Reduce operational risk and unnecessary cost
For facilities teams, this insight can be especially valuable. A commercial building may have complex water behaviour, with usage affected by occupancy, cleaning, catering, washrooms, plant equipment and tenant activity. Real-time data provides the visibility needed to separate normal use from avoidable waste.
Water efficiency is also a risk management issue
Water waste is not only an environmental issue. In commercial buildings, it can also become a financial, operational and insurance risk.
Undetected leaks can lead to property damage, disruption, repairs, tenant complaints, increased bills and potential claims. For landlords, facilities managers, insurers and estate operators, earlier detection can reduce both waste and risk.
This is why water insight matters. Better data allows organisations to move from reactive management to proactive control. Instead of waiting for problems to become visible, they can identify abnormal consumption early and take practical action.
That shift is important. Water efficiency should not rely on guesswork. It should be based on clear, timely and actionable information.
Every action matters, but visibility makes action smarter
The Let’s Save Water campaign is right to focus on everyday actions. Shorter showers, repairing dripping taps, using full loads in washing machines and dishwashers, and reducing unnecessary water use can all make a difference.
But the next stage of water efficiency is about connecting behaviour with insight.
People are more likely to change behaviour when they can understand the impact. Businesses are more likely to reduce waste when they can see where it is happening. Facilities teams are more likely to act quickly when live data shows something is wrong.
In other words, awareness starts the conversation, but insight drives the action.
Better water decisions start with better water insight
Water is one of the most important resources we use every day, but it is also one of the easiest to overlook.
The national message is clear: water needs to be treated as precious. The challenge now is helping households, businesses and organisations make that message practical.
At Quensus, we believe better water decisions start with better water insight.
Smart water monitoring gives people and organisations the visibility they need to understand consumption, detect waste and make targeted improvements. From shorter showers and fixing dripping taps, to live monitoring across commercial estates, every action matters.
But with real-time insight, those actions become measurable, practical and far more effective.
Water efficiency is no longer just about using less.
It is about understanding more.
