2 Indianapolis Nation s largest partnership 20-Year partnership with incentive-based fee structure Comprehensive scope 1 million people 200 MGD water production 4,000 mile distribution network Operations & Maintenance Support capital improvements Customer service $5M R&D program with IUPUI on watershed management Community relations

3 Challenges in Indianapolis Nation s largest water partnership Approximately 1 million people served Good news Customer satisfaction now well exceeds national utility average Taste-and-odor complaints down from 501 in 2001 to <20 in 2008 Challenges Capacity of facilities and distribution is rated at 213 MGD design capacity Consumption ranges from peak demand of ~120 MGD in March to peak demand of 230 MGD in summer Lawn watering million gallons daily! Water treatment and distribution 3

4 Immediate steps to educate the public! Radio, TV and print campaigns in 2007, 2008 and 2009 June 29 August : 19 million impressions Community outreach to 60+ organizations Reinforced via media relations and Web site Water advisories issued in 2007 peak periods via odd/even addresses + several days where consumers were asked to voluntarily stop watering lawns

5 Customer survey data Customer report a very high level of voluntary compliance (85% modified lawn watering habits) Customers perceived the water use advisories were reasonable and justified (92% totally or mostly justified) 2009 ordinance adopted giving Mayor the authority to issue advisories

7 Aimed at largest water users both home and commercial use, turning sprinklers off when raining. Top-level unit is a moisture unit measuring soil.

8 Every drop does count! Awareness is the first step. Correlation between public education outreach and what people are reporting as their behavior Outreach required that every communication include a conservation message every meeting, every ad, every public communication Standard utilities will net increased profit during summer months 75 MGD of capacity is readily identifiable but substantial capital investments would be required to support behavior only occurring in peak months we re pushing sustainable solutions not capacity!

9 Tampa Bay Water Largest U.S. DBO underscores cost-avoidance possibilities TBW member governments Hillsborough, Pinellas, and Pasco Counties, St. Petersburg, Tampa, and New Port Ritchey TBW currently provides drinking water to 2.5 million citizens TBW is a special district and wholesale water provider 1998 Master Water Plan led to shift away from groundwater toward difficult-to-treat surface water TBW saw Design-Build-Operate as a possible fast-track solution that could still surpass state, federal and TBW water-quality standards Veolia selected in April 2000, team delivers 66-MGD facility at beginning of 2003 Helps save $80 million on a projected $200 million project 9

10 DBO model leverages diverse skill sets; allows staged approach and cost-avoidance Enabled single point of responsibility and accountability Partnership proved technological approach, established working relationship and operations knowledge Second phase expansion to 120 MGD awarded in fall of month construction schedule Cost-plus structure with incentives $127M in capital expansion costs Risks for performance and costs taken by private-sector partners DBOs combine engineering, construction and operations skills. Cost avoidance can be rich. Project is cornerstone of Master Water Plan and a model of efficiency Scaled approach: 1998 to 2010 delivery can be adapted as a model

11 Metering and demand management Demand management promotes efficient use of water, including load management and load reduction (conservation!) Leakage = inefficient use and inefficient waste of power, chemicals, labor and treatment facilities and system assets to treat and deliver water that is not being used costs that could be avoided! Two North American cities easily demonstrate inefficiency related to leakage Mexico City s unaccounted-for water estimated at 45% Montreal s unaccounted-for water estimated at 40%+ versus Paris, which accounts for all but 10% of its water and Indianapolis at approximately a respectable 15% level Leakage problems can t really be addressed without effective metering
