London, July 15 - Hollywood actor Matt Damon has launched a new charity drive to provide millions of impoverished people with clean drinking water.

The 'Bourne Ultimatum' actor has co-founded Water.org in collaboration with humanitarian Gary White. Damon's existing water charity -- H20 Africa -- will merge with White's WaterPartners to become one non-profit organisation, reports contactmusic.com.

Damon aims is to provide access to clean water to 890 million people across Africa and Asia and insists it was his heart-wrenching visits to the world's poorest countries that 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,' said the actor.
