  11. 11. A Look at Success: WATERGY makes the best use of two valuable, limited resources: water & energy WHY IS THIS IMPORTANT?  Every liter of water that passes through a system has a significant energy cost .  Water sector efficiency leaves more funds for crucial and often underfunded public services .  In most developing countries, 1/3 to 1/2 of water produced is lost. AND IT’S COST EFFECTIVE …  Rapid Payback : generally from a few months to 3 years  Huge Savings : at least 20% in energy costs; much higher possible  Makes the most of existing infrastructure ; reduces the need for new supplies RESULTS: 20.8 million kWh and $5.3 million (100 cities)
  12. 12. WHY WATERGY in the U.S.? WHY IS THIS IMPORTANT?  3% of U.S. energy consumption goes to deliver potable/waste water services = $4 billion in energy costs = 45 Million tons of GHGs AND IT’S COST EFFECTIVE…  Rapid Payback: generally from a few months to 3 years  Huge Savings: at least 20% in energy costs  EPA estimates 10% reduction in energy use would save $400 million annually
  13. 13. PROBLEM • 80% of water flowing to homes lost through leaking plumbing fixtures! • Enough to fill two Olympic-size swimming pools every hour CASE STUDY: EMFULENI, South Africa
  14. 14. TECHNICAL SOLUTION: Pressure Management • Automated pressure management valves on each supply line • Reduced high bulk pressure; further reductions @ night • $800,000 construction commissioned Sept 2005 FINANCING SOLUTION: Performance Contracting • Water pressure management firm acting as ESCO • Build-Operate-Train-Transfer to municipality after 5 years • Fees: firm gets 20% of savings EMFULENI, cont.
  15. 15. RESULTS • Payback period: <3 months • Annual Savings: Money : US $ 3.8 million Water : 8 million kiloliters (kL) a reduction of >30% Energy : >14 million kWh • CO2 Reductions: 12,000 tonnes/year EMFULENI, cont.
