A major public campaign is being launched in the UK to encourage people to reduce daily water use as the country emerges from a period of extreme heat. The campaign, called Let’s Save Water, aims to shift public behaviour by treating water as a limited and valuable resource rather than an unlimited household utility.

The GBP 75 million campaign will ask people to reduce their water use by around 28 litres per day, equivalent to about two large buckets. Average daily use is currently around 140 litres per person, which is higher than in several comparable European countries. In Germany and the Netherlands, average use is closer to 120 litres per person per day.

The campaign is being supported by water companies, Ofwat, the Environment Agency, the Met Office and Natural Resources Wales. It comes at a time when hotter summers, population growth and water-intensive industries are increasing pressure on the UK water system.

Water shortages in England are projected to reach 5 billion litres per day by 2055 if no major action is taken. This future deficit reflects a combination of climate change, population growth, ageing infrastructure and increasing demand from sectors such as data centres.

The recent heatwave showed how quickly demand can rise. Yorkshire Water reported that customers used around 150 million litres more water than usual for this time of year during the hot weather, enough to supply Leeds for a day. Higher demand was linked to garden watering, paddling pools, additional showers and general heat-related use.

Climate change is making water management more difficult. Wetter winters, drier summers and more intense rainfall events mean that water may not be available when it is most needed. When heavy rain falls on dry, hardened ground, much of it runs off instead of infiltrating into the soil and replenishing natural storage.

The campaign will encourage practical household actions such as taking shorter showers, fixing dripping taps, using water butts, running full washing machine and dishwasher loads, and replacing inefficient shower heads. A standard shower can use about 10 litres of water per minute, so even small reductions in shower time can make a measurable difference.

However, public behaviour is only one part of the issue. Water companies are under pressure because leaks account for around 19 percent of water demand, and more than 3 billion litres of drinking water are reportedly lost through leaking pipes each day. Public trust has also been weakened by sewage pollution, supply interruptions, company debt and concerns over regulatory performance.

This makes the campaign more complex. Asking households to save water may be reasonable, but it must be matched by visible action from the water industry. Reducing leakage, investing in reservoirs, improving network resilience and communicating transparently will be essential if the campaign is to gain public support.

The UK’s water challenge is not only about individual habits. It is also about infrastructure, climate adaptation and long-term planning. Saving water at household level can help, but the larger test is whether the water system can become more resilient before future heatwaves and droughts place it under even greater stress.
