Located inEast Cairo, Gabal el Asfar is the main was-tewater treatment plant forgreater Cairo, reaching around 8million people. Phase II of this projectentails the construction of the nextphase of the Plant’s capacity extensionmeant to provide an additional waste-water treatment capacity of 500,000m3/d. One particular aspect of this plant,aside from its contributions to publichealth and sanitation, is its contributionto tackling climate change through thereduction of greenhouse gas emis-sions, typically high at waste-water treatment plants. Me-thane, a by-product of wastewater treatment,is more than 20times more effectivein trapping heat inthe atmospherethan carbondioxide. Rather thanbeing released intothe environmentwhere it would contri-bute to climate change,the methane gas will be captu-red and used to supply about 60-70percent of the plant’s energy require-ments. The extension will bring the total treat-ment capacity at Gabal El Asfar plant to2.50 M m3/d that will serve about 2.5million more people, a necessary up-grade of Cairo’s sewage treatmentmaster plan, srcinally designed in 1978for a population of 20 million people li-ving in an area of over 1100 km2. Ca-pacity building is also to be provided wi-thin the responsible institutions to ope-rate the plant as well as to fulfill their so-cio-environmental responsibilities, forexample the promotion sanitation andhygiene.  The project is expected to solve the is-sue of wastewater discharge into irri-gation and drainage canals, pollutingEgypt’s limited water resources, the Nileand Lake Manzala, and creating an en-vironment where water-borne diseasesflourish. Executed by the Construction Authorityfor Potable Water and Wastewater, theproject launched in 2009 is expected tobe completed by 2014. The total costof Stage II Phase II of GAWWTP is es-timated at Euro 233.5 million. The pro- ject will be jointly financed by the AfricanDevelopment Bank – 23 percent fromthe Agence française de développe-ment, and 21 percent from the AfricanDevelopment Fund- and the Govern-ment of the Arab Republic of Egypt,which will cover 55 percent. Sanitation and climate mitigation Reduction of Greenhouse Gas Emissions Waste Water Treatment PlantEgypt Gabal el Asfar Wastewater Treatment Plant Project Stage II Phase II  I n order to control increa-sing and repeated floo-ding in the city of  Yaoundé, the Govern-ment prepared a Yaoundé City Sanita-tion Master Plan,which was financedby the AfDB andcompleted in July1996. It served asthe basis for prepa-ring a project toconduct works on theemergency phase of  Yaoundé City RainwaterDrainage, which mainly comprisesthe re-calibration of the Mfoundi and thecleaning of the collectors.  The overall objective of the Yaoundé Sa-nitation Project is to contribute to healthand poverty reduction in the urbanareas, by adapting the drainage systemto unfavorable and worsening climateconditions causing the flooding. Its spe-cific goals are to help limit the effects of floods that disrupt the city’s socio-eco-nomic activities and more so of the poorsquatter areas that cover about 62.4percent of the area of Yaoundé City.  The lack of rainwater drainage in atown like Yaoundé, where rain-fall is considerable, nearly2000 mm a year, hasfar-reaching impactson the population. The main rainwaterdrainage systemsare regularlyblocked by alltypes of solidwaste. As a result,during the rainy sea-son floods, estimated at15 to 20 per year, about53,000 people are regularlyflooded and an additional 243,000 per-sons occasionally. Dwellers sometimesmove away temporarily or continue tolive in the humid, filthy and unhygienicsurroundings.In addition to the discomfort causedby these floods, their effects on health,the environment and the economy aresignificant. Floods cause latrines tooverflow, polluting drinking water wellsthat become breeding sites for larvaeform and waste carried by the rain wa-ter, subsequently increasing the spreadof waterborne diseases. They also pol-lute the water treatment station of  Akomnyanda, which supplies the townof Yaoundé with drinking water. Fur-thermore, floods cause the destructionof houses and businesses as well asloss of incomes for traders. The project will have a direct and im-mediate impact on poverty reductionby improving the health of the people,creating about 1350 direct jobs and2350 indirect jobs during the 4-yearimplementation phase and reducingthe unemployment rate, especiallyamong youths. The actions plannedwithin the project context will also bringabout increased empowerment of themost vulnerable population groups, in-cluding women and youths, a betterorganization of urban communities aswell as the promotion of small opera-tors such as jobbers, craftsmen, daylaborers, SMEs and NGOs.Increasing the performance of the drai-nage system constitute Yaoundé’s res-ponse to a changing climate, throughpreventive, far-sighted planning.  The AfDB contributed about 40 millionUSD to this project.  African Development Bank  Water & Sanitation Department F        O      N     D    S    A   F    R   I   C   A I  N   D E  D  E   V   E   L   O    P    P     E    M     E      N       T    A     F    R    I   C  A   N   D  E  V E L O  P  M   E   N   T    F      U     N     D           B      A      N     Q    U     E   A    F   R   I  C A  I  N E D E   D  E   V    E   L  O   P    P    E     M     E      N       T          A    F     R    I     C   A  N   D  E  V  E L O  P  M   E   N    T  B    A    N     K  AfDB Durban South Africa28 November - 9 December 2011 Flood management and climate adaptation Controled flooding YaoundeCameroon
