A vision for future wastewater system of alexandria city= 21 22 june 2010

47

Published on

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.

Dr. Sama MZ Presented by Dr. H.A.Helaly 4th International Conference on “Healthy Water for Healthy Arab Citizens” Cairo 21-22 June 2010 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.
