The school ran a variety of fundraising activities, from non-uniform days and cake sales, to more unusual events such as a wine tasting evening for parents, a sponsored 48-hour virtual rowing event and a fishathon. The headmaster, David Levin, defied jellyfish and battled strong tides to complete two long-distance swims in the Atlantic and raise more than £35,000 for WaterAid. All the money raised will go to support WaterAid's work in Zambia, which some of students visited earlier this year to see how their fundraising efforts can transform lives through access to safe water and sanitation. Leo Gundle, Chairman of the Charity Appeal, was part of the group travelling to Zambia. He said: "The video made on our trip to Zambia galvanised the school into fundraising activities during the summer term. With the full effort and enthusiasm of the school, we were enabled to raise such a sum. "In Zambia, we met Fenny Bangi, who has looked after her grandchildren since their mother died. Last year, two of them died aged six and seven from diarrhoea caused by drinking dirty water collected from their shallow well. Still, her and her family have no choice but to continue drinking this water. I've seen the difference water can make, and I’m really pleased our efforts will help transform the lives of people like Fenny." Fenny's story is not unique. Globally, 2,000 children die every single day from diarrhoeal diseases caused by dirty water and inadequate sanitation. Mr Levin said: "This year, pupils aged between 10 and 18 raised the cash through a number of fundraising events and activities, including sponsored walks and swims, Christmas and summer fetes and entertaining lunch-time events. They also demonstrated their stamina during a 48-hour sponsored row, which attracted much praise from City workers and alone raised over £8,000." Victoria Rouse, WaterAid Community Fundraising Manager, said: "Thank you to all the students, their parents and the teachers at City of London School for their fantastic efforts in raising such life-changing amount of money for WaterAid. "It can cost just £15 to enable one person to access safe water, sanitation and improved hygiene, so the school's donation will make a huge difference, transforming thousands of lives in Zambia."
