The Challenge

Thames Water supplies water to households and businesses in London, and are keen to encourage better water use practices by engaging students in local primary and secondary schools on water sustainability issues.

How we helped

H2O Heroes gives students the skills and support they need to design their own behaviour change campaign to get their fellow students and local community taking action to save water at school and in their local communities. We run workshops with students to get them thinking about how sustainable our water supply is, and encourage them to talk to their peers, teachers and family members about this issue. This helps students spot the ways that people waste water, such as showering for longer than five minutes. Using this knowledge, they put together an action plan to tackle water wasting behaviours in their school, and engage people from the school community along the way.

Each school involved also receives a free water audit.

Celebrating Success

Over the last three years H2O Heroes has been delivered in 33 schools, training 632 children.
Last year students got creative, seized the initiative, and produced some excellent campaigns. Posters, stalls, skits, videos, songs and water-themed board games are just some of ways they encouraged their audience to join the H2O Heroes mission.


One school that participated ran an ‘H2O Heroes Day’ engaging with over 500 pupils and collecting 700 pledges from parents and teachers. Another school went to their local church to talk about global water issues and encourage better water behaviours.


As they do each year, after their water saving campaigns, all of the fantastic participants came together in a Celebration Event at London’s City Hall. Here they showcased their campaign work and an overall winner was chosen by our panel of distinguished judges. Certificates of excellence were also awarded to schools alongside the overall H2O Heroes prize.

It’s great that it’s focused on kids. We can find out more and then carry on the positive actions when we’re grown-ups.
