Reenergize

The document discusses the close links between water and energy. It outlines how EPWU uses energy for water treatment and how water is used in energy production. EPWU has implemented successful water conservation programs that have saved over 231 billion gallons of water and 924 million KWH of electricity. EPWU is also working to increase use of renewable resources like solar power, reclaimed water, and converting wastewater digester gas to electricity to reduce costs and environmental impacts. EPWU partners with universities to conduct research on sustainable water technologies and solutions for the desert southwest region.

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 Water Source: Paul Reiter / International Water Association
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

desalination
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
Sustainable Solar Power Background  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
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
reclaimed water
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
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

wastewater
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
Advanced Reciprocating Engine Systems Generator
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
research
CHIWAWA Consortium 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
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
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
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
