Enhancing Focus on Sustainability - Water Utility

  1. 1. Daniel F. Haddock, P.E. Senior Project Manager Wittman Hydro, a Division of Layne 1
  2. 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 Economic Social full‐cost pricing of water public health Environmental, Social and  reinvestment in  reliability & level of  infrastructure Economic performance – service ability to attract capital employees Triple Bottom Line (2) affordability of service community goals &  priorities economic development 2
  3. 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) “Sustainable water resource systems  Utility Management are those designed and managed to  Full Cost Pricing 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) 3
  4. 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……. 4
  5. 5. Leadership in Energy & Environmental  Design (LEED) Leading measure of  sustainability in construction Water  Developed and administered by  Efficiency 5 US Green Building Council (5) Energy &  Atmosphere Adopted by 31 states, 12 fed  17 agencies, 172 localities (6) Sustainable  LEED‐NC for new construction Sites 14 Materials &  Resources LEED‐NC designed primarily  13 for office buildings, but applied  Indoor  to manufacturing, schools Environmental  Quality Multiple levels ‐ Certified,  15 Innovation &  Silver, Gold, Platinum Design Process 5
  6. 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 6
  7. 7. Initiating the Initiative American Water – A Case Study Recognized that many existing practices already  contributing to sustainability Water loss reduction through leak detection and obsolete  main replacement Meter replacement Preventative maintenance Full‐cost water rates, re‐investment in infrastructure LEED Certification appeared feasible without changes to  budget or schedule of project 7
  8. 8. Initiating the Initiative American Water – A Case Study Good fit with American Water expertise and  processes Design‐Build project delivery model facilitates  collaborative design and construction effort necessary  for achieving goal Life cycle cost analysis standard approach for evaluating  alternatives Expertise in full life cycle of facilities ‐ planning,  engineering, construction, operation enables thorough  evaluation of constructability, cost, and operability 8
  9. 9. Initiating the Initiative American Water – A Case Study Achieving Commitment Benefits demonstrate environmental  leadership motivating development  opportunity for employees Risks to be Mitigated Public utility commission support Schedule & Cost Implementation Plan Pilot projects Clear expectations and constraints Evaluation 9
  10. 10. LEED and the Water Utility American Water – A Case Study Moving Forward with Appropriate  Constraints Maintain focus on function, cost‐effectiveness,  value to rate paying customers. Decision making unchanged – alternatives  appropriately subjected to life cycle cost analysis Minimize risk by targeting lowest certification  level  Budget & schedule trump certification Communicate externally after feasibility assured 10
  11. 11. Implementation American Water – A Case Study LEED certification goal was identified in Requests for  Qualifications and Proposals for design build services Plans for achieving LEED certification were integral to the  proposals received from prospective design‐build teams Internal presentations at management and functional  group meetings Project team orientation – intent, concepts, goals,  constraints Project delivery unchanged 11
  12. 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 12

  23. 23. What was learned about LEED? American Water – A Case Study Design‐build project delivery  method is well suited to LEED No significant additional capital  cost at lower levels of LEED  certification Employees enthusiastic,  communities positive Established, structured program  helpful recognition of LEED “brand” process for project team to follow 23
  24. 24. What was learned about LEED? American Water – A Case Study Process “discovered” good  existing practices, new approach  stretched team to implement  others Practices broadly applicable to all  construction  variable speed drives to optimize  pumping  native vegetation energy efficient building materials site selection concrete specification – fly ash & slag recycle construction waste 24
  25. 25. And about sustainability? Learned that sustainability encompasses: Planning in a wider context and with a  long view Minimizing the environmental impact of  our activities Efficient management of water resources  – source water protection, treatment &  delivery, conservation, reuse Maintenance and upkeep of  infrastructure to maximize efficiency of  our assets & limited capital 25
  26. 26. And about sustainability? Learned that sustainability encompasses: Financial viability: full‐cost pricing of  water, rates that will sustain our  operations and support necessary  investment in infrastructure Development and retention of  qualified, motivated staff Climate change – prepare for drought  and flood, manage risks Communication with customers and  stakeholders about water issues 26
  27. 27. Sustainability is  integral to the core  Operations business of the  Maintenance Water Quality utility and involves  everyone Utility Management Engineering Human  Rates &  Resources Finance 27
  28. 28. Conclusion ‐ Benefits of  Implementing LEED Structured program is useful for  building awareness of issues of  sustainability affecting the business Demonstrate the environmental  leadership that our customers  expect Independent Recognition &  Publicity Energy efficiency and reduction in  greenhouse gas (GHG) intensity 28
