Supplying people with clean water is one of the planet's greatest challenges. The community of Ikwezi in South Africa's Eastern Cape province is suffering from extreme water shortages and bad water quality.Anyone needing water here used to have to carry it home arduously from far-away sources. Now,South Africa's first municipal water house has been opened. Now,besides clean drinking water,the 5000 residents have water toilets,showers and wash basins for their clothes - for the first time.
