  1. Suez Environnement experience in Water Management: Options for Indian Cities The 6th Euro India Summit Hyderabad October 21-22, 2013

  2. Suez Environnement – Over 140 Years of Experience Serving Local Authorities and Companies 1869 1880 1919 1971 1974 1869Inauguration of the Suez Canal1880Creationof Lyonnaise des Eaux et de L’ Éclairage1971Lyonnaise des Eauxbecomes the majority shareholder inDegrémont 1974Suez Finance Company becomes the main shareholder in Lyonnaise des Eaux 1997Mergerbetween Lyonnaise des Eaux and the Suez Finance Company, formingSuez Lyonnaise des Eaux 1999Majority shareholding in United Water (founded in 1869) 2002Combination of water, waste, and energy activities within Suez 2010 SUEZ ENVIRONNEMENT acquires AGBAR

  3. A Rs. 1 lakhCroreGLOBAL COMPANY: WORLD LEADER IN WATER & SOLID WASTE EUROPE 78% NORTH AMERICA 6% ASIA 4% AFRICA & MIDDLE EAST 7% SOUTHAMERICA 2% OCEANIA 3% WATER SOLID WASTE • 91 million people provided with drinking water and customer services • 240,000 kms water network managed • 1 billion inhabitants served by 10,000 Degrémont treatment plants • 61 million people served by1,643 wastewater treatment sites • 51 million people benefiting from waste collection • Over 464,985 industrial and commercial clients • 41 million tonnes of waste treated • 49 incinerators worldwide(46 of which provide energy recovery)

  4. SUEZ ENVIRONNEMENT MANAGEs SIX OF THE Largest FOURTEEN PPP contracts GLOBALLY…

  5. Suez has experience with all types of PPP Structures Concession Affermage BOT DBO 3 5 Years 25 Forever 10 Degree of Private Involvement Private Ownership Privatisation or USA, UK, Chile Delegated Management New Delhi-Malviya Nagar France, Macao, Jakarta, Casablanca , Barcelona… Infrastructure Contract Sydney , San Luis Potosi Perth , Los Angeles USA (75 contracts) Johannesburg, Amman, Algiers, … O&M Contracts Management Contract Mexico City, Durban Bangalore Technical Assistance Pimpri - Chinchwad Flexibility in managing all types of contractual offers

  6. But, PPP is not only about large investments or development of large project facilities….

  7. It’s about Prioritizing Objectives…. • Most Indian cities aim for: • Service improvement: 24/7 supply, good quality water, equitable distribution in the city • Increase the revenue (independent of tariff increases) and improve the local employees’ skills to achieve self-sustainability To achieve these objectives, a multi-process approach is essential 7

  8. Alternative PPP Structures Concession Affermage BOT DBO 3 5 Years 25 Forever 10 Degree of Private Involvement Private Ownership Privatisation or Delegated Management Infrastructure Contract O&M Contracts Management Contract Services Contract Technical Assistance Integrated Services Contract

  9. Such PPP Structures can help in customizing offer to meet City’s Objectives…

  10. Systematic Diagnosis: 38 IndividualProcesses A City can prioritize specific actions according to their objectives

  11. Illustration 1: Processes to improve water distribution Construction of new network is often required but it is never enough to achieve distribution improvement

  12. Illustration 2: Processes involved in increasing revenue by decreasing Physical and Commercial losses Decrease Physical losses Decrease commercial losses

  13. Cities can choose Services individually or in an integrated manner…

  14. Individual and Integrated Services These can be offered as individual services or combination of services depending on city’s needs and objectives

  15. Network Modeling & Equitable Distribution Objective: Build and calibrate Hydraulic Numerical Model (HNM) to achieve Equitable distribution across hydraulic zones • Analyse the existing hydraulic zones, including their network configuration and water demand • Defining the Service Levels • Building the Hydraulic Model for the Primary Network (from the MBRs to Service Reservoirs) • To suggest measures for pressure management in the existing hydraulic zones or redefined hydraulic zones. • Develop management rules for Operating staff to achieve equitable supply in the various hydraulic zones

  16. Invisible Leak Detection • Conventional Method - Acoustic Detection (Based on three basic Principles/ Requirements) • Requires water in the system to create noise at leak point • Requires high pressure in the systemto detect leak noise • No Background noise Interference: Preferable to be carried out during Night Time, as detection is affected by background noise • Advanced Method – Helium Gas based Detection (Suitable for Indian Conditions of Intermittent Supply) • Leaks can be detected even during period of ‘No Supply’ • Leak detection possible even in low Pressure • Detection can be carried out any time of the day • Accurate pin-pointing of leak is possible

  17. Invisible Leak Detection – Helium Technique Helium detector Operator 2 HeliumInjection Drills 3 Helium bottle Mass flow meter Flow meter Insertion He 1 Pit Pavement Sub-base Difussionzone Base 4 Main Natural terrain NV Leak NV Leak

  18. Helium Leak Detection – Results Worldwide • Helium based water leak detection • Regular practice in Suez Group for last 6 years. • Technique is also used in France, Middle East, South East Asia, Central America, and now started in Delhi, and Pimpri-Chinchwad • Leak Strike Rate is above 85% (Best compared to other techniques)

  19. Smart Metering Solutions & Online Network Management Objective: Smart network management using combination of AMR , Network meters & SCADA • Monitoring of Network performance • Online Information to the customer • Leak and fraud detection • Leak Alert • Billing accuracy (removing human error)

  20. We recommend Fixed Network AMR System • This is a management tool and not just substitute to meterreaders • Optimized Network Management • Large network management analysis • Real billing and no more estimation, avoidingbilling disputes • Allows a fastest leakage detection, frauds and default meters • Monitoring with AMR drives a better individual consumption • AMR system can save 5 to 10% water volume produced

  21. To Summarize… • Cities should prioritize their objectives and opt for specific ‘Services’ Projects in PPP mode • Leak Detection and Repair (Reducing Physical losses) • Metering and Customer Services (Reducing Commercial Losses) • Primary Network Management (Equitable distribution across city) • Smart Metering and Online Network Management • Reducing NRW • Contract Period: 6 months – 3 Years

  22. PPP is not only about large investments or development of large project facilities …PPP frameworks can also be adopted for efficient and cost-effective solutions

  23. Suez Environnement MAKING THE PLANET SUSTAINABLE IS THE BEST JOB ON EARTH Thank you for your attention
