Now in its fifth year, TW WESP is open to schools across London. It comprises:

 Free fun and informative water workshops for your pupils (Key Stages 1 – 4)

  • Free water audit for your school
  • Free benchmarking report for your school to determine whether the school is currently water efficient or not
  • Free water efficiency upgrades up to £500 in value to save your school water and money

Working in partnership with Thames Water, ech2o has successfully delivered “Be Water Aware” assemblies and workshops to over 22,000 pupils and 1,150 teachers in 85 schools over the last four years. We have worked in-depth with 11,530 pupils across all key stages, delivering a series of different workshop choices about using water sustainably. Thames Water realises that, as well as helping schools to save money by retrofitting water efficiency devices and identifying leaks, it is also important to teach pupils about why we all need to save water. This is a package programme, so schools need to sign up to the free water workshops to be eligible for the water efficiency upgrades.

This is the fifth phase of WESP. The previous four phases were a great success. ech2o visited 60 primary schools and 25 secondary schools predominantly across Enfield, Hammersmith, Hackney, Haringey and Waltham Forest. Pupils and teachers thoroughly enjoyed the workshops and significant water savings were reported in the majority of the schools. Schools can choose between a series of different workshops.

Water workshops

We work with your pupils to enable them to:

  • become more water aware
  • know how much water their schools uses
  • understand the environmental cost of water and its link to CO2 emissions
  • recognise what they can do to reduce their water use both at school and at home
  • meet the challenge to create a water aware school
  • understand how small changes by all pupils add up to a huge amount of water savings

“At the end of the day we expect to have achieved a more sustainable water culture among the pupils and a step change in behaviour that will save considerable amounts of water both at school and at home.” – Cath Hassell, Director at ech2o

 How it works

  1. Sign up to the water workshops by contacting us at ech2o via
  2. We will contact Thames Water to arrange the audit and the water efficiency upgrades.
  3. The school receives a useful water audit, great water efficiency upgrades, and fun and informative water workshops!

School feedback

It has been great to receive feedback from teachers, pupils and parents each year.

Great workshop. Pictures on interactive white board helped. Interactive with questions and actions which involved the pupils. Great resources left with teachers to give out (to send message home) and to use further in lessons and support the learning in class – Thank you!” (Teacher)

The feedback from our daughter was glowingly positive, she was hugely enthused by it and she clearly picked up a lot from it. She really does take a lot more care with water now, time spent in the shower, etc. And so far it has stuck, so you and Trevon changed her thinking“. (Parent)

Available Workshops
  • It’s raining in the zoo and Frankie the flamingo thinks she is sinking! So she sets off on a mission to find out why. Using the story of an inquisitive flamingo, a determined dragonfly and a crab who doesn’t like poo on his head, pupils discover why it is important to save water and the best way to do so.
  • This story is an uncomplicated, entertaining and educational way to engage Key Stage 1 pupils on the topic of saving water.
  • All pupils get a badge and a Frankie postcard to colour in.
  • Each class will receive five copies of the book ‘The mysterious case of the sinking flamingo’.
The mysterious case of the sinking flamingo (KS1)

ech2o will work with the school eco team or green team to:

  • carry out a water audit of the school
  • identify where and how the school could save water
  • prepare an assembly about what they have discovered.


Make your school water smart (KS1,2)

ech2o will work with a set of pupils to enable them to:

  • collect data about their use of water at home
  • work out where they are water smart and where they are water silly
  • identify whether they have a dual flush or single flush toilet and how a toilet works
  • find out the best behavioural changes to reduce their family’s water footprint.

Pupils get a shower (or bath) timer, stickers and badges.


Be a Water Detective! (KS2)

cath-and-see-though-cisternThis is a fun and informative short workshop using ech2o’s see-through toilet cistern to:

  • give a brief history of the WC,
  • explain why the toilet has its very own day in the calendar – 19th of November, World Toilet Day
  • remind pupils how lucky we are in the West to have them in our homes and schools, and what in would be like if we had to use a public toilet
  • demonstrate the  bits of kit that have been invented to make them work even more efficiently.

Pupils who don’t have a dual flush receive a free save-a-flush bag to fit in their WCs at home saving on average 5000 litres of water per family per year.

Can be delivered on its own but usually combined with ‘Be a water detective!’

How much does it cost to flush your toilet? (KS2)

clarence for website poss 1A workshop for pupils in Years 3 and 4 that builds on the story of Clarence, one of the stars of ‘The mysterious case of the sinking flamingo’, a crab who doesn’t like poo on his head. Pupils learn why and when this still happens in the UK, and the simple things that can be done to prevent it. Includes a walk around the school grounds to see if space can be found for a rain garden.

#pooonyourhead (KS2)

TW WESP Sec schools 2ech2o will work with the school eco team or green team to:

  • carry out a water audit of the school and identify where and how the school could save water
  • benchmark the school’s water use
  • design a strategy to reduce water use across the whole school community
  • Identify solutions to reduce rainwater run-off from the school premises.
Make your school water smart – design a sustainable water strategy for your school (KS3,4)
  • This workshop builds on the TW WESP Sec schools 1student’s knowledge of the hydrological cycle and the causes of global warming.

Pupil’s learn:

  • About the environmental implications of water and sewage treatment in the UK.
  • Why the UK is under water stress.
  • How sustainable drainage solutions and water efficiency strategies link into the UK’s environmental goals.
  • How personal water choices impact on climate change.
  • The link between hot water and increased CO2 emissions.
  • Initially designed and delivered for Year 10 Geography and Year 12 Applied Science pupils as a bespoke workshop. Later adapted for Years 7 and 8 Geography.
A sustainable water cycle (KS3,4)

TW WESP is your shower killing the polar bears slide

  • Pupils learn about the environmental implications of their water use and the link to CO2 emissions.
  • Pupils record their water habits and discuss what would motivate them to shower for less time.
  • Pupils decide how they can inspire their friends to do the same.
  • Workshop has been delivered in various formats including a classroom workshop to Year 11’s, as part of a PSHE immersion day and as a lunchtime stand with the school leadership team, on a whole school science and engineering immersion day.
Is your shower killing the polar bears? (KS3,4)
  • ech2o challenges the pupils to design a piece of kit or an advertising campaign that will reduce the amount of time people spend in the shower.
  • ech2o work with the pupils as they:
  • carry out market research to identify the class’s shower usage: good, average, bad, excessive
  • develop an understanding of the link between hot water use and climate change
  • brainstorm technological and behaviour change solutions to reduce shower use and present to focus group of other pupils
  • develop one or more of the solutions into a workable format
  • Usually delivered as a double lesson. Chosen by one school as a full day workshop for Year 7 Design and Technology pupils as part of their term project.

Take a look at some of the designs pupils created to encourage people to shower shorter here.
