  • • Expert Consultation Wastewater Management in the Arab World 22-24 May 2011- Dubai-UAE• Second Arab Forum Cairo Egypt November 2011 Session on Non-Conventional water resources

  • • The annual volume of wastewater discharged in untreated form in Arab region is 7.5 km3, which is 43% of the total wastewater produced in the region.• 57% of the wastewater generated in Arab region is treated, which is higher than Asia (35%), Latin American/Caribbean (14%) and Africa (1%)• 83% of treated wastewater used in agriculture,• most of the partly treated, diluted or untreated wastewater is used by urban and peri-urban farmers to grow a range of crops.
  • Financial• Institutiona Policy & l set-up & political personnel commitmen capacity t Health & Awareness environment - & Enforcement acceptance of standards - Monitoring Technical
  • High construction costs of treatment systems(esp. for small and medium size communities)High O&M costs, e.g. for electricity, equipmentmaintenance, investments in trained personnel –often not recovered by user feesCosts (and lack of funds) to build sewagecollection systemsHigh price of reclaimed WW vs. lowerfreshwater pricesPrice that farmers are willing to pay for reclaimedWW hardly covers O&M costs for WWconveyance and distribution <--> Croprestrictions
  • Reduce treatment operation costs, e.g. checkresearch on alternative operating conditions to saveelectricity; broader use of solar energy Focus on making reuse more profitable tofarmers (to ultimately recover more costs for reuse oftreated WW via user fees): Research ways to extend list of crops irrigated with WW, e.g. upgrade treatment or apply drip irrigation to avoid contact of crop with WW
  • Reclamation and reuse of Marrakech wastewater •Project cost : 15 Million EurosCapacity: 100 000 m3/dayProduction (electricity) 16 MWh/day33 Million m3/year are reused to irrigate 17 golfecourses60 km of Pipes and 4 Pumping Stations
  • Methane gas generated in the anaerobicbasins is recovered and converted toenergyTreated wastewater is sold to farmersfor irrigation purposesReeds from reeds beds are harvested andsoldSewage sludge is dried and compostedwith other organic solid wastes in orderto produce compostCharging a wastewater fee forconnection to sewage
  • Economical Aspect• Concentrate on demand-driven planningof reuse projects• Cost benefit and cost recovery should beintegrated for sustainability of any reuseproject• Diversify the reuse• Encourage PPP in wastewater treatmentand reuse•
