International Congress SmallWat07: Wastewater Treatment in Small Communities Seville – Spain 11 - 15 November 2007 National Office of Drinking Water (ONEP) THE ONEP EXPERIENCE FOR WASTEWATER TREATMENT IN SMALL COMMUNITIES:CURRENT SITUATION AND PROSPECTIVE Mahi Mustapha Direction of sanitation and environment Office National de l’Eau Potable (ONEP)1 OUTLINEOUTLINE OFOF THETHE PRESENTATIONPRESENTATION z Presentation of the National Office of Drinking Water (ONEP) : drinking water and sanitations activities z Wastewater characteristics: The concentration decreases when the population increase is due to the dilution of wastewater. z Wastewater treatment plan in small communities: The adoption of waste stabilization ponds allows the effluent quality to respect the WHO guidelines and the Moroccan standards z ONEP development Plan of sanitation z Master plan of Sanitation: launched in 2005 (PNA, 2005), in partnership between: Ministry of Interior and the Ministry of the Water and Environment. The major objectives of the Master Plan of Sanitation (MPS) z Some examples of wastewater treatment plant in Morocco z Reuse of wastewater and Farmers awareness 2 OfficeOffice NationalNational dede ll’’EauEau PotablePotable (ONEP)(ONEP) The National Office of Drinking Water (Office National de l’Eau Potable ONEP) is responsible for water supply in major part of the country especially in small and middle communities. It also is responsible for sewerage facilities in some cities. The ONEP is in charge of the following tasks : z Planning of the water supply at the national level z Studying, executing and managing potable water supply z Controlling water pollution z Studying with the concerned departments, the development of legal and regulatory texts. In September 2000, ONEP has been given an additional responsibility: sanitation in middle and small communities. This new responsibility will enable ONEP to transport, collect and treat wastewater if requested by the municipalities. 3 Water resources in Morocco m3/hab./year 2500 2000 1500 1000 Resources mobilized 500 Natural resources 0 1965 1970 1975 1980 1985 1990 1 Threshold of water stress RESOURCES MOBILISEES 995 2000 2005 2010 2015 2020 2025 4 The potential of Wastewaters in Morocco z The actual potential of wastewaters : 600 Mm3/year z Distribution of wastewater discharged according to the receiving natural environment: - 60% (360 Mm3) : Mediterranean Atlantic Coast - 40% (240 Mm3): Rivers and Talwegs z Only 8% of wastewater is treated z Some area is directly irrigated with wastewater without treatment. z Volume of wastewater will not exceed 4.2% of the water resources 5 WastewaterWastewater qualityquality inin MoroccoMorocco Parameters (less than 20.000-100.000 more than National 20,000 inhab inhab 100,000 inhab average BOD5 (mg/l) 400 350 300 350 COD (mg/l) 1000 950 850 900 TSS (mg/l) 500 400 300 400 Restitution 50 75 80 65 rates (%) Supply x 40 70 80 60 restitution rate(l/inhab) 6 BEN HMED PLANT EL AROUI PLANT 7 KELAAT M’ GOUNA PLANT OUARZAZATE GALLERY ONEPONEP developmentdevelopment programprogram ofof wastewaterwastewater treatmenttreatment 8 ONEP’s sanitation Program 2007-2010 In million of Dirhams (1 Euro = 11 DH) Total 2007- 2007 2008 2009 2010 2010 1 176 1 000 1 000 1.000 4 176 9 The performance indicators of ONEP’s sanitation program Désignation 2003 2010 connection Rate 69% 80% reduction Rate / 7% 60% Total pollution Elimination of the reuse by non treated wastewater on 38 cities 10 NationalNational MasterMaster PlanPlan ofof SanitationSanitation z The national master plan of sanitation is launched in 2005, in partnership between: Ministry of Interior and the Ministry of Water and Environment. The Major objectives of the National Master Plan of Sanitation (NMPS): z To increase the rate of total connection to the network of sanitation at 80% in urban area z To eliminate 60% of the pollution generated by wastewater z The program targets 260 cities sheltering 10 million inhabitants at 2020 z Possibility of wastewater reuse 11 EvolutionEvolution ofof wastewaterwastewater volumevolume EVOLUTION OF WASWATER DISCHARGE VOLUMES (Mm3/year) 1200 1000 800 600 Volume 400 200 0 1960 1975 1990 2005 2020 Year 12 Consistency of the National Master Plan of Sanitation The consistency of the national master plan of sanitation : z Rehabilitation and extension of the networks and connections z Reinforcing the rain network z 260 wastewater treatment units z Renewal of the equipments The program was estimated at approximately 4,3 billion € including 1,2 Billion € for the component treatment. This cost does not include the over cost related to the treatment for the reuse. 13 WastewatersWastewaters reusereuse 14 WastewaterWastewater reusereuse projectproject inin MoroccoMorocco Plant Ouarzazate Ben Sergao Ben Slimane Marrakech Drarga Processing Lagoon Filtration- Aerated Lagoon Filtration- System percolation Lagoon percolation Implementation ORMVAO DGCL ONEP/ MILD Marrakech Department of FAO-OMS- RAMSA Canadian Sciences- Environment PNUD (Department Contribution university and Community of IAVHII of interior) Municipality Marrakech Drarga of Ben municipality ERAC-Sud Slimane Beginning Date 1989 1990 1997 1985 2000 of O&M Design capacity 430 m³/d (5 750 m3/d 5.600 m3/d 380 m³/d 1.000 m³/d l/s) (4,4 l/s) Population- 4 300 15 000 37 000 3 000 8 000 equivalent (PE) 15 WastewaterWastewater reusereuse projectproject inin MoroccoMorocco There are many studies of wastewater reuse : • Study relating to the wastewater reuse project for Mogador’s golf • study relating to the wastewater reuse project for agriculture in the cities of Al Hoceima, Imzouren, Bni Bouayach and Targuist. • Other project is initiating on downstream of wastewater treatment plant built by ONEP such as Guelmim, Tiznit etc. 16 LegalLegal AspectsAspects z Law 10/95 : • Prohibition the discharge of wastewater or solid waste; • Application the penalty for discharge of wastewater and fixes the limited pollution value ; • Prohibition the reuse of wastewater without treatment in agriculture; • Sets the quality standards to the discharge of wastewater • Sets the quality standards for wastewater reuse in agriculture. 17 ConstraintsConstraints toto thethe developmentdevelopment ofof wastewaterwastewater reusereuse projectproject z Deficiency and/or no application of the low and regulation; z Coordination between the different Moroccans institutions; z Technical capacity concerning wastewater reuse ; z Weak financial capacity to recovering cost of the wastewater reuse project; z Limited capacity financial of the simple farmers. 18 Conclusion • Capitalize the national and international experiences of wastewater reuse • To sensitize the donors, in order to support the realization of the reuse and wastewater treatment projects, • Creation of a subsidy fund, for the wastewater and reuse projects to encourage the wastewater reuse 19.
