This weekend the WaterAid charity will be at the famous WOMAD festival in Charlton Park.

Representatives will be using the long weekend to tell festival-goers about the vital need for water and sanitation in developing countries.

"WOMAD provides the perfect opportunity for WaterAid to make the link between providing plenty of water and hygienic toilet facilities at events in the UK and the need for water and sanitation in developing countries," said Jennean Alkadiri, WaterAid's campaign manager .

"This year we'll be asking festival-goers to sign up to the End Water Poverty campaign, demanding sanitation and water for all."

Throughout the three-day event a team of 20 volunteers will be busy manning the stall, providing clean drinking water, hand washing facilities and most importantly, keeping the cleanest set of toilets on the festival site.

To sign up to the campaign, revellers will be asked to put their thumb print on the giant End Water Poverty hands.

Festival goers should also look out for WaterAid's infamous poo; one daring volunteer will be dressing up as a poo to spread the message that lack of sanitation and lack of safe water kills.
