    1. 1. October 26 – 27, 2011 Ed Archuleta, P.E. President/CEO
    2. 2. Water and Energy Are Closely Linked Water for Energy Extraction & Refining Hydropower Fuel Production Thermo Electric Cooling (Ethanol, hydrogen) Extraction and Wastewater Treatment Transmission Energy Associated Drinking Water with Uses of Water Treatment Energy for WaterSource: Paul Reiter / International Water Association
    3. 3. Energy for Water/Wastewater Over 90% of energy used by EPWU is for water and wastewater processing In 2010, EPWU used more than 178 million KWH, or enough to supply 30,000 homes In 2010, EPWU spent approximately $15 million on energy

    6. 6. water
    7. 7. Water ManagementMeeting demand and long-term sustainablegoals through:  Planning  Diversified water resources  Strong conservation program  Growing reclaimed water system
    8. 8. Diversified Resources Conservation Reclaimed Water Groundwater (Bolsons stable) Surface Water (Rio Grande) Desalination Water Rights (East of El Paso)
    9. 9. Water Conservation ProgramReduced potable water use through: 1991 Conservation Ordinance – establishes landscape watering schedule – prohibits water-waste – provides for enforcement Tiered rate structure Rebates and incentives Education
    10. 10. Water Conservation Results Water & Wastewater In the past 20 years, EPWU has: Power Costs  Saved 231 billion gallons of water; $20 Increased Fuel Costs and enough water to fill the Sun Bowl 6,392 Desalination Facilities times  Avoided the generation of 924 million $15 KWH of electricityMillion  Avoided pumping more than 277 millions gallons of water to produce this $10 electricity $5 2006 2007 2008 2009 2010

    14. 14. desalination
    15. 15. Solar Power at the KBH Desalination Plant EPWU is interested in developing alternatives that are renewable, sustainable and reduce EPWUs carbon footprint El Paso is an ideal location for solar power EPWU has retained an engineering firm to evaluate the different types of technologies available and the economic feasibility of this project
    16. 16. Sustainable Solar PowerBackground  Demand is minimum 500kw for 1 skid operation up to 2300kw demand for 5 skids or full production capacity  Desalination Plant places peak demand burden on El Paso Electric grid
    17. 17. Benefits of Solar Power Reduces peak demands on EPE system grid Frees up EPE system capacity Reduces critical peak demand charges paid by EPWU for the plant Sustainable, renewable energy source Reduction of greenhouse gases
    18. 18. reclaimed water
    19. 19. Reclaimed Water Recycled wastewater that has received advanced treatment to improve its quality Uses include landscape irrigation, industrial processes including cooling, and construction projects Reduces use of potable water during peak It takes 12-14% less energy to produce reclaimed water than potable water for irrigation
    20. 20. Reclaimed Water  Over 47 miles of pipeline installed  2.62 billion gallons produced in 2010-11  9.3 million gallons for construction in 2010-11  System expansion underway

    22. 22. wastewater
    23. 23. Digester Gas Co-Generation Wastewater plants generate solids (sludge) that are digested to produce biosolids and gas The gas is primarily methane Historically EPWU used the gas to generate electricity Due to emerging contaminants, that practice stopped about 20 years ago (also, natural gas in recent years has been relatively inexpensive) The gas is currently flared Available new equipment is vastly improved
    24. 24. Advanced Reciprocating Engine Systems Generator
    25. 25. Digester Gas Co-Generation While treating wastewater, EPWU produces an average of 229.1 million cubic feet of methane gas per year By scrubbing this gas and using high efficiency co-generators, EPWU will generate 12.93 million KWH per year This will result in gross electricity savings of $772,260
    26. 26. research
    27. 27. CHIWAWAConsortium for Hi-Technology Investigations in Water and Wastewater• EPWU, UTEP, Texas A&M Agri-Life Research Center, NMSU, City of Alamogordo• Promote research and training programs in salinity management, inland desalination technology, concentrate disposal, and water resources management• Goal: development of new technologies and processes to assist the Southwest region and other parts of the world in developing reliable and sustainable sources of water
    28. 28. Center for Inland Desalination Systems (CIDS)• UTEP and EPWU to establish nation’s premier center of excellence for inland desalination and engineering research and education• Non-exclusive 5 year Memorandum of Understanding• Includes strategic plan: business plan, research plan, education service plan
    29. 29. Continuing Research El Paso is a living laboratory for water/energy research Problems of being situated in a desert present enormous opportunities for not only research but also manufacturing EPWU’s contract with the Regional Economic Development Corporation seeks to recruit industries to locate here
    30. 30. Summary Conservation not only conserves water but also energy EPWU will power the desalination plant (the largest inland plant in the world) with solar energy EPWU is a national leader in sustainable research
