Alexandria Effluent

Reuse is a key of minimizing expected

climatic changes impacts.

Presented by Dr. H.A.Helaly

1- Minimize sea water soil intrusion problem.

2- Preventing flooding problems and sea pollution from

pumping the mixed lake maryout water and disposed

wastewater from Qalaa drain, Noubaria Drain and West

treatment plant outfall.

3- Improve climatic condition of the west desert of Alexandria.

Alexandria Effluent Reuse is a key of minimizing

expected climatic changes impacts.

Alexandria wastewater system in the Future.

Complete reuse of wastewater effluent in arid areas of the

western desert. And be used as an effective tool to fight

desertification and solve Lake Maryout pollution problems.

Switching to Decentralization management .

Achieving balance in restoring costs of operation and

maintenance, through using appropriate technologies and

environmentally friendly methods in wastewater treatment.

The overall goal of the effluent reuse project is to

catalyze change towards more sustainable urban

water management in the

"City of the Future”.

Factors affecting the wastewater system

in the future

Factors affecting the 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

Wastewater production and STP’s capacity (Master plan 2037)

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$ …..)

Therefore, it is important to en light “ Effluent Reuse”

Alexandria effluent Reuse Definition:

Is the optimum use of Alexandria treated effluent

through appropriate technologies and the best
