Water Treatment History:The history of water treatment dates back to ancient times when people first began using water from rivers and lakes for drinking and other purposes. Early methods of water treatment were simple and usually involved boiling the water or using a cloth to filter out impurities. As civilizations grew and more people began using water from shared sources, it became clear that more effective methods of water treatment were needed to prevent the spread of disease.One of the earliest recorded examples of water treatment was in the Code of Hammurabi, a set of laws compiled in ancient Babylon around 1750 BC. The code included a regulation stating that all houses in the city must have a connection to the public sewer system. This was likely one of the first attempts to control pollution and protect public health by preventing contaminated water from being used.
