In order to achieve Alexandria strategic vision for 2037, the future vision for the wastewater system will be fulfilled through: Effective wastewater system establishment; Ensuring and improving aquatic environment of Lake Maryout as one of the major priorities for improving future Alexandria wastewater system as well as providing a new water resource; Achieving full cost recovery of operation and maintenance expenses and ultimately total cost recovery of future wastewater system to sustain, preserve, and enhance the quality of the wastewater system.

Alexandria city is expected to face the following challenges:
• Water Demand Increase (population, economic, industrial and social activities).
• Semi-arid zone (little rain fall 150-200 mm/year).
• Limited groundwater Potential (Fresh, 3 million m3/year).
• Down stream main irrigation system.
• Water quality degradation (44% Industrial Activities of which 60% is petro-
chemical Activities)
• Climate Change (sea rise, 19 km2, 1.5 million person , 30 million US$ …..)

Factors affecting the water and wastewater system in
the future
1. Population growth, city expansion and wastewater flows
2. Wastewater composition, industrial discharges and the enforced effluent
standards
3. Demand for effluent (industrial, urban and agricultural reuse; location,
required qualities and potential quantities)
4. Intrusion of saline water into the sewer system
