Population growth, city expansion and wastewater flows • Water Demand Increase (population, economic, industrial and social activities). 2. Wastewater composition, industrial discharges and the enforced effluent standards • Semi-arid zone (little rain fall 150-200 mm/year). • Limited groundwater Potential (Fresh, 3 million m3/year). 3. Demand for effluent (industrial, urban and agricultural reuse; location, required qualities and potential quantities) • Down stream main irrigation system. • Water quality degradation (44% Industrial Activities of which 60% is petrochemical Activities) • Climate Change (sea rise, 19 km2, 1.5 million person , 30 million US$ …..) 4.

Using on-site sanitation systems in sub-urban and far rural non-served areas onsubnonaround Alexandria to decrease costs of construction, operation and maintenance. And reusing its effluent in irrigating wood trees, flowers and green areas, instead of disposing in agricultural drains and creating a code for residential facilities to ensure separating grey water from black water to decrease treatment costs through using low-cost technologies in treating liquid waste from those areas. low- 3-Achieving full cost recovery of operation and maintenance expenses and ultimately total cost recovery of future wastewater system 4- Sustain, preserve, and enhance the quality of the the wastewater system Presented by Dr. H.A.Helaly Dr. Sama MZ 4th International Conference on “Healthy Water for Healthy Arab Citizens” Presented by Dr. H.A.Helaly Dr. Sama MZ 4th International Conference on “Healthy Water for Healthy Arab Citizens” Cairo 21-22 June 2010 Cairo 21-22 June 2010 ٨ • A Vision for future wastewater system 2037 ٧ • A Vision for future wastewater system 2037 : 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 through : Improving Wastewater System Management skeleton to ensure sustainable effective services, to reduce the environmental impacts resulting from increasing amounts of wastewater resulting from extension in tourist, commercial and industrial activities west Alexandria and from new industrial zones in Amriya, Om Zeghio, Merghem and El-Nahda. All Alexandria will be covered by a wastewater Elsewer system. Thus, extending the wastewater systems in Alexandria and surroundings through Continuous improving Quality control and management of the operated sewerage systems.. Establishing a suitable storm water collecting system, to be reused with a minimum cost, and collected into water bodies that can be self purified Presented by Dr. H.A.Helaly 4th International Conference on “Healthy Water for Healthy Arab Citizens” Cairo 21-22 June 2010 coned……. Wastewater system should be protected from the intrusion of saline water and increasing its levels, by isolating sewer lines, manholes and pump stations to minimize the effect of rise in sea water level, to ensure decreasing dissolved solids levels in wastewater system. Thus, to minimize the effect on the final quality of wastewater effluent that will be reused to overcome decreased River Nile water level, and deficiency in rainwater amounts. The reused effluent will be used completely in agriculture and un-edible industries within the city of Alexandria. un- Increasing the treatment level to tertiary treatment throughout the city’s treatment plants. Thus, increasing the efficiency of self purification of all water bodies that receive treated wastewater from wastewater treatment plants. Dr. Sama MZ Effective wastewater system Establishment • A Vision for future wastewater system 2037 Presented by Dr. H.A.Helaly Dr. Same MZ 4th International Conference on “Healthy Water for Healthy Arab Citizens” ١٠ Cairo 21-22 June 2010 ٩ • A Vision for future wastewater system 2037 Ensuring and improving aquatic environment of Lake Maryout as one of 4 / 6 the major priorities for improving future Alexandria wastewater system as well as providing a new water resource through Ensuring and improving aquatic environment of Lake Maryout as one of 4 / 6 the major priorities for improving future Alexandria wastewater system as well as providing a new water resource through Complete reuse of secondary effluent in irrigating forest trees to overcome the shortage in pure water supply in el-Hammam area through the National elplan for irrigation as the option suggested by the WRc study, this is a corner stone to ensure improving aquatic environment of Lake Maryout. Increasing the treatment level to tertiary treatment throughout the city’s treatment plants. Thus, increasing the efficiency of self purification of all water bodies that receive treated wastewater from wastewater treatment plants. Establishing an emergency system for disposal of secondary treated effluent in case of storms and accidents to minimize different impactes. Establishing a suitable storm water collecting system, to be reused with a minimum cost, and collected into water bodies that can be self purified Adopting the large scale reuse range of Alexandria wastewater treated effluent in surrounding arid areas outside Alexandria ,especially from small treatment plants.

  3. 3. ٠٥/٠١/١٤٣٠ • A Vision for future wastewater system 2037 • A Vision for future wastewater system 2037 Sustain, preserve, and enhance the quality of the the wastewater system through: Achieving full cost recovery of operation and maintenance expenses and ultimately total cost recovery of future wastewater system through Ensuring an adequate tariff for wastewater treatment system service, to ensure adequate budget for operation and maintenance of the wastewater system. Adopting decentralization systems in Management, collection, treatment and reuse systems, to overcome poor availability of financial resources Public environmental awareness to ensure that all Alexandria and Borg ElElArab residences use the sewer system properly Increasing levels of cooperation with all Local and international granting authorities to fund solutions to environmental problems relating to primary treated effluent, and raw sewage from rural areas disposing into drains leading to Lake Maryout. Decreasing the O&M costs of treating sludge which will be produced from future wastewater treatment systems, through producing electricity from sludge using anaerobic digestion, this will lead to decrease in using electricity from the main national facilities and producing partially treated sludge before drying. This will lead to decrease in hydrogen sulphide levels thus avoiding its impact on mechanical dewatering facilities and the environment, and decreasing mal odors at site 9N. Also, agricultural wastes can be used in producing safe sludge compost by mixing with sludge, leading to improving the organic content and assuring continuous decrease in heavy metals levels as much as possible. Necessary arrangements with all concerned authorities to reuse treated wastewater to save raw water for economic and tourist developments. Progressive reduction of industrial contaminants entering the sewer system should remain a long- term objective of environmental and longregulatory authorities in Alexandria to increase the sustainability of improving the wastewater system. Presented by Dr. H.A.Helaly Dr. Sama MZ 4th International Conference on “Healthy Water for Healthy Arab Citizens” Cairo 21-22 June 2010 Presented by Dr. H.A.Helaly Dr. Sama MZ 4th International Conference on “Healthy Water for Healthy Arab Citizens” ١٤ Cairo 21-22 June 2010 ١٣ • A Vision for future wastewater system 2037 Sustain, preserve, and enhance the quality of the the wastewater system through: Continuing upgrading and improving Industrial Waste Management Program to minimize the problems identified with the discharge of industrial wastes into the wastewater system. Thus, reach the level that all industrial, commercial and tourist facilities treat their liquid waste according to Law 93 year 1962 and its regulation 44 year 2000, and pay the 2000, cost of receiving and treating their organic load which is higher than the permitted levels in domestic wastes especially in new industrial areas in Borg el Arab – Om zeghio – Merghem – El Nahda – Amriya and inside Alexandria. Constructing industrial complexes and collecting each type of industry together to minimize the cost of constructing new treatment plants also to minimize operation and maintenance costs. This will create a new market for the waste of each industry to reach zero exhaust.
