Who We Are

Waterwise is an independent, not-for-profit UK NGO focused on reducing water consumption in the UK.  We support and challenge governments, industry, customers and others to be innovative and ambitious on water efficiency. We are the leading authority on water efficiency in the UK. Our work includes research, events, technological and policy innovation and media.

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.

We have published a Case for Support document, which outlines why you should support us, our track record, our plans for the future and how we use funding from Waterwise Supporters and Affiliates.


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.

I am very interested in... read more
  • 2019 London Climate Strike

Myself along with two Waterwise employees attended the 2019 climate strike, outside Westminster alongside 100,000 others. The march was on Friday 20th September and was... read more

  • Dual flush toilets save water, apart from those that leak!
    Dual flush toilets save water, right? Of course they do, they must do. Giving the option to flush that pee away with just two-thirds of the cistern flush volume absolutely saves water. Full stop. It’s much more sensible than using the full flush every time. However, there’s a darker side to the humble drop-valve dual... read more

Water Facts

The average Brit uses about 140 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.
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.
