  • First you should be sure of the flow and head requirements and then select the pump to operate in this point at maximum efficiency. The motor has to be selected so that the loading is maintained high. Energy efficient motor can be considered during new installations. Provide appropriate meters and log data so that analysis becomes easy. Where large variations are expected, multiple pumps have to be judiciously selected and operated for maximum efficiency.

    • 1. Energy Management in Water Supply Systems Pradeep Kumar 18 th October,2010 Bangalore Building Livable Cities,2010 EcoCities : Driving India towards age of sustainability
    • 2.
      • “ The Alliance to Save Energy promotes energy efficiency worldwide to achieve a healthier economy, a cleaner environment, and greater energy security”
      Mission Statement:
    • 3. Who is the Alliance to Save Energy?
      • Established in 1977
      • Non-Profit
      • A leader in energy efficiency in all relevant sectors:
      • • municipal • industry • buildings
      • • utilities • appliances • transportation
      • • research • policy • education
      • • federal government (e.g., FEMP)
      • Experience in over 30 countries
      • Recognized as municipal/cities energy efficiency expert
    • 4. The Alliance’s Municipal Experience - India
      • Tamil Nadu
      • Madhya Pradesh
      • Maharashtra
      • Andhra Pradesh
      • Gujarat
      • Delhi Jal Board (DJB)
      • Municipal Corporation of Greater Mumbai ( MCGM)
      • Vishakhapatnam MC
      • Pune MC

      • ~ Incorporating efficiency into water supply,
      • including the design of water infrastructure systems,
      • is a critical means of controlling costs while expanding access ~
      •  By 2020, over 50% of the population in developing countries
      • will live in urban areas  
      •  An increasing strain on governments to provide water AND energy
      •  The cost of using traditional approaches to water infrastructure
      • is well beyond the means of most communities.
      •  For financial viability of water provision over the long-term:
      • consumption-based pricing (politically sensitive!).
      Cities Can ’ t Afford to Follow an Inefficient Path
    • 6. Facts:
        • Every liter of water that passes through a system has a significant energy cost , compounded by the money invested to produce it.
        • In developing countries, the cost of energy for supply of water may easily consume up to half of a municipality’s budget.
        • Energy expenditure is the second largest cost after labour.
        • Cities spend an estimated 30-40% of their annual expenditure towards energy charges
        • 1/3 of India's urban population lacks direct access to clean, affordable and reliable water services
    • 7. Overview- Indian Municipal Sector
      • Second Largest Municipal System in the World
      • India’s Municipal sector consumes 4% of total electricity
      • Energy Consumption by Public Water Works
        • 2.57% relative to total Energy Consumption by all Sectors
        • 12,000 Million Units in absolute terms (2006‐07)
        • 19,200 Million Units ( projected for 2011-12)**
      • Energy Consumption by Public Lighting
        • 1.17% relative to total Energy Consumption by all Sectors
        • 5,500 Million Units in absolute terms (2006‐07)
        • Data source: BEE/CEA
    • 8. Energy Efficiency Challenges for Indian Cities
      • Cities lack technical, managerial and financial capacity to implement projects
      • Lack of metering & monitoring systems - difficult to establish baseline
      • Connected load estimated energy consumption doesn't match with the actual energy bills **
      • High rates of unaccounted for water; unreliable water services
      • No existing Government policy on reducing energy consumption in water delivery;
      • Low confidence in PPP- Fair deals take time to set-up
      • Procurement is based on ‘ first cost ’ ( L1) NOT on Life Cycle Cost
      • ** few cases
    • 9.
      • Why Municipal Energy Efficiency ?
    • 10. Benefits - Municipal Energy Efficiency
      • Extremely Cost Effective (20 to 40% saving potential)**
        • This translates to at least 4000 MUs of energy savings
        • Simple Payback 2 to 3 years
        • Reduces the need for new infrastructure
        • Avoid the need for an additional capacity of 600 MW
      • In National Interest
        • Reduced energy intensity will help climate change mitigation efforts
        • Reduce demand and supply gap at the national/state level
      • Improved Municipal Services
        • Time to incorporate best practices
        • Better and more reliable services to community
        • Enhanced service level
    • 11. Measures to Improve Efficiency and Typical Payback Periods
    • 12.
      • Manual for Development of
      • Municipal Energy Efficiency Projects
      • A Reference Guide
    • 13. Purpose of the Manual
      • “ Serves as a practical tool for anyone interested in being a part in the development, financing and/or implementation of municipal energy efficiency project through a performance contract”
    • 14. Manual for the Development of Municipal EE Projects in India
      • Manual for EE projects in India was developed jointly with IFC and BEE
        • BEE has endorsed the manual as a standard reference document for ULBs and other stakeholders interested in Municipal EE.
      • Includes guidelines on:
          • Self assessment
          • ESCOs
          • IGA
          • Procurement
          • Financing
