The ancient Egyptians dug a long canal called Bahr Yousuf to bring water from the Nile to the Faiyum Depression for irrigation. Egyptians developed a system of Nilometers at various points along the valley. This was helpful in comparing past and present water levels. Water storage was not attempted by the Egyptians.
From the beginning of human history, people have sought ways to keep and transport fresh, clean water. The Romans built aqueducts to provide water in the cities, animals skins were used to transport water by a more portable means, clay and woven materials were molded into water carrying devicesâ¦the list goes on.
