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.
Before the development of aqueduct technology, Romans, like most of their contemporaries in the ancient world, relied on local water sources such as springs and streams, supplemented by groundwater from privately or publicly owned wells, and by seasonal rain-water drained from rooftops into storage jars and cisterns.
