cosmicsolutions Discover The Mystery Of Ancient Civilizations

"Standardized earthenware plumbing pipes with broad flanges making use of asphalt for preventing leakages appeared in the urban settlements of the Indus Valley Civilization by 2700 BC. Plumbing originated during the ancient civilizations such as the Greek, Roman, Persian, Indian, and Chinese civilizations as they developed public baths and needed to provide potable water, and drainage of wastes.

Improvement in plumbing systems was very slow, with virtually no progress made from the time of the Roman system of aqueducts and lead pipes until the 19th century. Eventually the development of separate, underground water and sewage systems eliminated open sewage ditches and cesspools."

"As early as 6,000 BC farmers used irrigation to control floods and to guide water to areas where they could grow barley, even in areas where there was not enough rainfall. The ancient Mesopotamian also were among the first to use water caches to store excess water for times of drought.

This basic skill, of bringing water to crops to expand arable land and increase food production, is still a fundamental skill of farmers around the world today."
