The water fountain, or Aquascript, spelt out the names of WaterAid supporters who had texted the word ‘everyone’ and their name to 78866 or tweeted their name using the hashtag #Everyoneeverywhere.
HSBC is WaterAid’s biggest corporate partner and its HSBC Water Programme, which aims to reach 1.1 million people in Asia and Africa with safe water, supported the Aquascript.
Oritsé Williams, a member of the band JLS, attended the Aquascript’s launch yesterday and his name was the first to be displayed on the wall of water.
Chris Goode, the European coordinator of the HSBC Water Programme who visited WaterAid projects in 2013, said: "I saw the impact of WaterAid’s work first-hand when I visited Ghana. In one school we visited, by simply installing toilet and hand washing facilities, attendance and enrolment had increased by almost 25 per cent.
"The HSBC Water Programme is funding improvements to so many lives and we’re really proud to support WaterAid."
The Aquascript took place today and yesterday.
