Unfortunately not everybody in the world has access to clean water. Over 60% of the world’s population suffer from lack of water and have no access to clean, safe drinking water. The situation in third world countries is especially worsened by environmental disasters, drought and long, raging wars. | ||
It is our responsibility to help - We want to help
Since May 2005 we have been supporting the well building project of the charity organisation ‘Plan International Deutschland’. The wells sponsored by CWT provide clean water to over 300 people daily in the African town of Guinea. |
