The gap between the needs and availability of water is about 20BCM/yr. Shallow Groundwater in the Nile aquifer cannot be
considered a separate source of water. The aquifer is recharged only by seepage losses from the Nile, the irrigation
canals and drains and percolation losses from irrigated lands. Hence, its yield must not be added to Egypt’s total
water resources. Therefore, it is considered as a reservoir in the Nile river system with a huge capacity but with
only 7.5BCM/yr rechargeable live storage. The current abstraction from this aquifer is estimated at 6.5BCM in 2013
(Fig. 1). This gap is overcome by recycling (MWRI, Egypt, 2014). The agricultural drainage water provides an integral
supplement to Egypt’s water supply. Much of Egypt’s water is used multiple times on its journey through the country
(Fig. 2). On the last, drain estuaries discharge to coastal marine bodies; Lakes or Mediterranean Sea directly (Barnes,
2012).
