What We Do

Everything we do drives and promotes water efficiency.

We actively support and challenge everyone to aim high on water efficiency for the sake of people, the environment and the economy.

This means we work in a range of areas, including influencing and shaping policy and legislation; driving strategic and practical ambition in the water sector; designing and delivering research; media, campaigns and promotion; running demonstration projects; promoting water-efficient technology; helping businesses be more water-efficient; facilitating partnerships; brokering new solutions; and training water efficiency practitioners.


Water Efficiency Strategy UK

Waterwise’s Water Efficiency Strategy for the UK was developed in consultation with the water sector – including Waterwise Supporters and the Water UK-supported steering group. It sets out a blueprint to deliver a vision of a UK in which all people, homes and businesses are water-efficient, and where water is used wisely, every day, everywhere.


Water Saving Week 19-23 March

Waterwise are hosting Water Saving Week for the fourth year running. As before, there’ll be an exciting range of activities to raise awareness about why we need to save water, including daily challenges, ideas and tips to help you do it. To stay up to date and find out what’s going on, keep an eye on our website, search #watersavingweek on Twitter, check out the daily themes, take on our challenges and get involved!


Leadership Group

The Leadership Group on Water Efficiency and Customer Participation is a Waterwise initiative, launched with the UK water industry in June 2017. Building on work to date, it brings together senior UK water industry leaders in a more ambitious approach to wasting less water – using this to drive a more customer-led culture.

The Leadership Group offers a new opportunity to involve customers in thinking about their future water services. Motivating people to take action, and empowering communities through rewards, could change the way we think about water, and revolutionise services. Waterwise is challenging and supporting the sector on ambition and innovation – within individual companies and across the sector.

Water Facts

The average Brit uses about 150 litres of tap water a day, but if you include the amount of water embedded within products, our water consumption increases to about 3400 litres a day.
To produce just one pint of beer for example, takes 170 litres of water.

It takes 200,000,000 litres per second to grow food for the planet.

Human Blood is 83% water.

If the entire adult population of England and Wales remembered to turn off the tap when they were brushing their teeth, we could save 180 mega litres a day-enough to supply nearly 500,000 homes and fill 180 Olympic swimming pools! (One Olympic sized pool is 1 million litres / 1Ml)

A dripping tap wastes around 5,500 litres of water a year: that's enough water wasted to fill a paddling pool every week for the whole summer.

70% of the Earth is covered with water but only about 1% of the world’s water is readily available for human use. Nearly 97% is salty or otherwise undrinkable. Another 2% is locked in the ice caps and glaciers. That leaves just 1% for all humanity’s needs.

If the entire world’s water were poured into a 4 litre jug, the fresh water available for us would equal only about one tablespoon.

Over 90% of the world’s supply of fresh water is located in Antarctica.

If everyone in the UK cut one minute off their shower we would save 1,420 million litres of water a year.

There is the same amount of water on Earth as there was when Earth was formed. The water from your tap could contain molecules that dinosaurs drank.

One cotton t-shirt has about 25 baths full of water embedded in it.

Water regulates the Earth's temperature.

Water is the only mineral that is found naturally on Earth in three forms; liquid, gas, solid.
More than half (63%) our daily water consumption at home originates from the bathroom and the toilet.
