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.
The Assyrians built the first structure that could carry water from one place to another in the 7th century BC. It was 10 meters high and 300 meters long, and carried the water 80 kilometres across a valley to Nineveh. Later, the Romans started building many of these structures.
