Washington, July 15 : Matt Damon has launched a new charity campaign to provide millions of impoverished people with clean drinking water.

The `Bourne Ultimatum' star is the co-founder of Water. org alongside humanitarian Gary White.

Under the collaboration, Damon''s existing water charity, H20 Africa, will merge with White''s WaterPartners to become one non-profit organisation.

And with his campaign the actor is trying to provide access to clean water to 890 million people across Africa and Asia.

Damon has claimed that it was his heart-wrenching visits to the world''s poorest countries, which made him realise the importance of having drinkable water.

"Every 15 seconds, a child in the developing world dies from water-related disease. After visiting project sites in Africa and Asia with Gary, I''ve seen the problem and the impact of safe water," Contactmusic quoted him as saying. (ANI)
