Abstract
Water is crucial to human life, but it can also be a killer. Water contaminated with micro-organisms or chemicals, which is then used for drinking or cooking, is a leading cause of disease and death across the world. Poor facilities for the disposal of sewage and other waste water can quickly lead to the spread of dangerous diseases.Lack of efficient drainage systems and flood defences can lead to catastrophic flooding as has been seen in several different areas of the world in the past few years.The ‘World water’ videos focus on how engineers and scientists work to provide us with safe, clean drinking water, efficient and clean methods for disposing of our waste water and practical drainage solutions.
