H2O Heroes celebrate water saving success at City Hall Students from 5 London schools gathered together on Friday 5 May for the H2O Heroes celebration event. The event, hosted at City Hall, marked the end of this year's H2O Heroes programme and was an opportunity for schools to showcase their water saving campaigns. This year, 157 students aged between 7 and 15 developed and implemented their own campaigns in their schools, resulting in estimated water savings of 1.5 million litres per year. Schools competed to be crowned overall winner - with three shortlisted schools presenting in the Chamber Room. The judges, consisting of representatives from the Greater London Authority, Thames Water and Global Action Plan, were impressed by the students' creativity and hard work. One student from participating school Middle Park Primary said that her favourite part of the programme was that “you could get everyone involved, and everyone saving water.” Students from Middle Park Primary School, who won the Student Leadership award. Trinity Church of England School, Belvedere, was named the overall winner. Judges were impressed by their ambitious efforts to extend the reach of the campaign outside the school’s immediate community to include, amongst others, four local primary schools and a church. They also wowed the judges with a beautiful water-saving song, and some very creative posters. The other schools present at the event were also recognised for their efforts, receiving awards for Creativity, Embedded Action, Student Leadership, and Outreach. The winning group will be rewarded for their win with a trip to Thames Water’s Walthamstow Reservoir, which will include an angling lesson and a tour.
