Water Efficiency and Reuse Project Southern California Regional Planning Initiative Participating Counties: Los Angeles, Riverside, San Bernadino, San Diego and Tia Juana September 2010

Outline Existing Root Cause Issue Solutions New Regional Concept Solutions –Efficiency –Treatment Technology

Existing Cities and Counties Southern California Population Boom Same Drinking Water and Sewage Water Concept for Localized Treatment –Limited by old world technologies –Lots of energy required! –Large green house gas footprint

Root Cause Issue Rocky Mountain Institute Study –Energy cost 2 cents per kilo-watt hour A LONG TIME AGO –Most systems today optimized around this cost –This includes engineering handbooks for traffic and all civil infrastructure; and mechanical engineering!!! –This is a major find and this has not been corrected –This is a ROOT CAUSE of the problems we face today! –All the science and engineering professional are optimizing systems using charts that are not developed with todays energy costs! –Some engineers are developing there own charts using Life Cycle Analysis with the current costs of energy and creating sustainable designs

Solution RECOMMENDED ACTION –Check with City of San Diego, Los Angeles and Riverside and San Bernadino and Tia Juana Mexico –Engineering charts to DESIGN for right energy cost! –Include GREEN HOUSE GAS (CO2(e)) Footprint –Include cost of other air, water and soil pollution in the Life Cycle Assessment Cost Analysis –Show how traffic lessens the economy –Show how excessive home with no jobs and quaility of life is a BAD economic model! –Present this information and correct this situation with real data – is available and has been!

New Regional Concept Rocky Mountain Institute –Using correct energy costs –The current engineering models work for cities up to 200,000 people in size –And, with large cities the cost to pump both drinking water and sewage does not justify the existing designs

Solution Efficiency –No water urinals –Home toilets with two flushes No to low for urine Low with pressure for other –Low water appliances EPA Water Sense EPA Energy Star

Solution New technology –Drinking Water New chlorine standards less because of health issues created Electro-Cogulation Plate Technology Lowest Cost and very effective –EXAMPLE Denver Colorado Area – (Call them for a tour!) Use Nano Ozone 10x oxidation reduction potential meaning 10x less cost –EXAMPLE –Both Above Technologies Save Energy, Cost –Supplement Chlorine for Pipe Travel to Homes –With money saved and improved quality, subsidize water efficiency devices for sale in Southern California

Solution Sewage Treatment –Both prior technolgies mentioned can be applied –Electro-coagulation applied to Denver Colorado Area River Water input from sewage plant better then river water input –Nano-ozone may also be used with electro- coagulation to futher save monies Money savings applied to water efficiency projects Output water can be used for irrigation!!!

Solution New technologies are PORTABLE! Develop neighborhood, community, smaller regional drinking water and sewage treatment plants SAVE ENERGY COST Use treated sewage water for localized irrigation! New infrastructure paid for with ENERGY SAVINGS and OTHER COST SAVINGS!
