Alexandria city is expected to face the following challenges:
Factors affecting the water and wastewater system in
the future
Presented by Dr. H.A.Helaly
Presented by Dr. H.A.Helaly
1. 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. Intrusion of saline water into the sewer system

Continuous upgrading and improving the wastewater system according to the
current Alexandria Master Plan.
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.

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

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.

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.

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.

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.

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

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

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.
