  1. International Workshop on Sewage and Waste Management River Basin Management and Waste Water Treatment Models – Experiences from Germany and other parts of the World Delhi. September 22-23, 2011

  2. Outline1. The Challenges2. The German Experience3. Innovative Approaches4. The Future5. Conclusion

  3. GIZworldwide • GIZ operates in morethan 130 countries worldwide. • In Germany wemaintain a presence in nearly all thefederalstates. • GIZ employsapproximately 17,000 staffmembersworldwide,

  4. GIZ Water Portfolio • Waste water treatment and management • Support to water sector reforms, including regulation • Support to sustainable water supply and sanitation • Tools and processes for water resources management • Support to transboundary water management • Adaptation and mitigation to climate change and it´s impacts

  5. 1. The Challenges

  6. Shortcomings of the traditional system

  7. 2. Experience of riverbasinmanagement and wastewatertreatmentfrom Germany

  8. • Industrialization • Mining • Population explosion … … • Floods • Cholera, typhus, malaria • Problem for the economic development Foundation in 1899

  9. Know-how since over 100 years

  10. Technological solutions for diverse waste water problems

  11. The RhineRiver length: 1,230 km watershed: 185,000 km2 draining off: 2,290 m3/s politicalstructure: 9 countries population: ~ 55 M drinkingwater: for 5.5 M shipping: > 200 M tons ~ 20 % hazardous 50 % of the entire chemical industry of Europe riverused for:hydropowerwastewatercoolingwatertourism ...

  12. River Monitoring and ManagementConventionsandLegal Acts International and National Monitoring and Management Programmes • 1950 International Commission for the Protection of the Rhine (ICPR) 1950 • 1963 German Commission for the Protection of the Rhine (DK) 1963 • 1963 Federal Water Act • 1978 WasteWaterCharges Act

  13. The Rhinebasinis anInternational RiverBasinDistrict (IRBD) Organisation International Co-ordinationisessential  International Commisssion for the Protection of the Rhine (ICPR)

  14. 57monitoringsites Monitoring Programme 2007-2012 About 200 parameters

  15. Trend MonitoringParameters National and international monitoringprogrammes: approx. 200 parameters • Guide parameters(watertemperature, oxygen, pH, electr. conductivity) • Nutrients(phosphorous und nitrogencompounds) • Mineralicsubstances(kations, anions) • Heavy metals • Hazardousorganicmicrocompounds, esp. “prioritysubstances“(pesticides, PCB, PAC etc.) in water, suspended matter, sediment.

  16. Alarm Monitoring Network = major chemical industry = directintake for major watersupply 16

  17. Alarm Monitoring Rhine Elements of Alarm Monitoring: At 6 monitoringstations „Alarm Monitoring“ with extra effort 1.Online monitoring of chemical-physicalparameters 2.Search for hazardous industrial compounds and pesticides(„Screening“) 3. Continuousregistration of toxicitywithcontinuousbiotestmethods („Biomonitoring“)

  18. EmscherGenossenschaft and LippeVerband, West Germany 4,145 km² Total area Wastewater treatment of: 60 WWTPs 60.000 LD - 300 MLD 230 Pumping stations Catchment Area Emscher / Lippe

  19. Wastewater Treatment in Germany • Number of wastewater plants 10.000 (mostly private) • Length of public sewer system 0.54 million km • Length of private pipeline network 1 million km • Sewage sludge disposal 2 million tonnes dry solids per year • Level connection sewer system 96% Use of sewage sludge

  20. 1950 No wastewatertreatment Withwastewatertreatment 2000 Pollution in the Rhine River 1970

  21. 3. Innovative Approaches

  22. Subsumption of Reuse of WasteWater • Socio-culturalAspects and Acceptance • Requirement on Technology • Requirements on Plant Management and Operational Competence • Health Aspects • Legal Regulations and State Controls • Market Potentials for Projects for Water Reuse • Pricing and Financing Software Tool for Selection of state-of-the-art Treatment Technology

  23. Project Pimpri-Chinchwad (Wastewater treatment) • Develop Wastewater treatment plant of capacity 120 MLD under PPP • Construction, running of plant and distribution of treated water to local industry shall be done by SPV • No discharge of existing STP output into the river • Sell the water at competitive Market price to the end users MORYA GOSAVI TEMPLE JULELAL TEMPLE PIMPRI WAGHERA

  24. Project Pimpri-Chinchwad (Wastewater treatment) Process: • Appropriate Ultra Filtration technology will be adopted according to the parameters of the outlet water supply of existing STP. Water use is limited to Industrial use. 2. Ultra filtration technology is used to satisfy required quality of water. Reverse Osmosis technology is used in special cases. Output: • Supply of 120 MLD water per day to the surrounding Industries. • No disposal of water back to river. • Less consumption of fresh river water in the industry.

  25. Project Pimpri-Chinchwad (Wastewater treatment) Treated waste water for industrial use Typical investment cost: Rs.120 Crore

  26. Ultrafiltration

  27. Project Pimpri-Chinchwad (Wastewater treatment) Intake Secondary Water Parameters • Effluent Tertiary Treated Water Parameters

  28. Project Pimpri-Chinchwad (Wastewater treatment) PPP Model to be adopted Lease Rights for 25 years Project SPV (Built and Operate) Water supply Development rights on land PCMC Industry Fee Charged Design support, Formation of SPV, Selection of Developer, Monitoring and reporting GTZ-IS Smooth running of project

  29. Economic Viability – Model 1 • Finance and Operation • Cost for design, construction, operation and Maintenance by SPV through sale of water • Supply of raw waste water by municipality • Sale of treated waste water by SPV • Current market price of the water – • INR 28 per cubic meter • Regulatory support • 30 percent usage treated of waste water by industry • No usage of ground water by industry through own well

  30. Economic Viability – Model 2 • Finance and Operation • Cost for design and construction by Municipality • Operation and maintenance by Municipality • Sale of treated waste water by Municipality • Municipality is selling on market price • Regulatory support • 30 percent usage of treated waste water by industry • No usage of ground water by industry through own well.

  31. 4. The Future

  32. Challenge 1: World Population Growth Source:IWAR,TUD

  33. Challenge 2: Urbanization

  34. Challenge 2: Urbanization

  35. Challenge 2: Urbanization

  36. Challenge 3: Limited resources • Water • Population Growth • Increasing living standards • Higher personal water consumption • Higher water consumption in agriculture • Energy • Energy and Water are linked • Fuel Abstraction, Power Production, Cooling • Energy for extracting, treating and distributing water • Energy for (domestic) water heating/cooling • Nutrients/Materials • Nitrogen, unlimited but energy intensive • Phosphorus, a limited resource...
