Sing for Water was initiated by Thames Festival Trust and composer Helen Chadwick in 2002 as a choral project which raises money for WaterAid.
To date, Sing for Water has raised over £1 million for WaterAid projects in Africa and Asia.
This year all the money raised will go towards communities in Malawi. Choirs from London and around the UK learn a repertoire of songs chosen by Roxane Smith and Katie Rose and are then sponsored to perform in a concert at the Scoop.
