  • 2. Got Sustainability? “…development that fulfills  the needs of the present  Graphic – broad concept Environmental generation without  efficient resource use compromising the abilities of  adaptation to climate change minimization of waste future generations to meet  preservation of biodiversity their own needs.”(1) Focus on long‐term  performance Social Economic public health full‐cost pricing of water Environmental, Social and  reliability & level of  reinvestment in  infrastructure Economic performance – service ability to attract capital employees Triple Bottom Line (2) community goals &  affordability of service priorities economic development 2009 © American Water Works Association 2009 Utility Managemnt Conference Proceedings All Rights Reserved 2
  • 3. Sustainability and the Water Industry The water industry is naturally  concerned with sustainability public health protection of natural  resources long asset lives requiring long  term view EPA Four Pillars (3) Utility Management “Sustainable water resource systems  Full Cost Pricing are those designed and managed to  fully contribute to the objectives of  Efficient Water Use society, now and in the future, while  Watershed Approaches to  maintaining their ecological,  Source Protection environmental, and hydrological  integrity” (4) 2009 © American Water Works Association 2009 Utility Managemnt Conference Proceedings All Rights Reserved 3
  • 4. What Does Sustainability Mean  to People? In a practical sense ‐ is it  immediately clear to people  how sustainability relates to  their own work? How many different perspectives are there in your utility  organization? Operations, Engineering, Water Quality, Finance, Human  Resources……. What does it mean to different stakeholders? Customers, Employees, Regulators, Investors, Taxpayers, NGO’s,  Other Users of Water Resources……. 2009 © American Water Works Association 2009 Utility Managemnt Conference Proceedings All Rights Reserved 4

  • 6. Bringing Sustainability Into Focus  American Water – A Case Study In late 2005, American Water embarked on an  initiative to pursue LEED certification for four new  water treatment facilities to be built in Illinois and  Indiana. Structured framework and goals of LEED provided  playing field for wrestling with concepts of  sustainability Sustainability into Focus Connection of sustainability to their jobs Existing sustainable practices were “discovered” Search for new opportunities began 2009 © American Water Works Association 2009 Utility Managemnt Conference Proceedings All Rights Reserved 6

  • 12. Initial Challenges American Water – A Case Study Skepticism of real value, viewed as an “extra” thing, a distraction Common assumption that it would increase costs, could present risk to  recovery of investment in rates Required stretching beyond familiar designs LEED‐NC was not designed for water treatment facilities, many  measures are not practical Challenges overcome when: It was clear that decision making would not be distorted by  certification goal It was appreciated that sustainability goals are well aligned with  fundamental priorities and not a change of direction Enthusiasm of project team members made stretching beyond  familiar approaches fun 2009 © American Water Works Association 2009 Utility Managemnt Conference Proceedings All Rights Reserved 12
