Calculate your Water Footprint at H2O Conserve

  1. 1. H 2 O Conserve’s Web-based Water Calculator Conserve Water, Protect Life
  2. 2. What is H 2 O Conserve? <ul><li>a developing nonprofit program promoting a community-based approach to water conservation and water supply protection </li></ul>
  3. 3. H 2 O Conserve’s Mission <ul><li>H2O Conserve encourages people to conserve and protect water as a vital natural resource by raising awareness about water use and threats to the water supply through educational tools including a web-based water calculator. </li></ul>
  4. 4. Water Footprint Calculator <ul><li>Web-based tool that gives you an estimate of the total amount of water you use, otherwise called your water footprint . </li></ul><ul><li>H 2 O Conserve currently focuses its calculations on water use in the United States. </li></ul>
  5. 5. Direct Water Use <ul><li>Water seen flowing from </li></ul><ul><li>the fixture down the drain </li></ul><ul><li>Shower : Regular = </li></ul><ul><li>3.8 gallons/min.; </li></ul><ul><li>Low-flow = 2.3 g/m </li></ul><ul><li>Toilet : Regular = </li></ul><ul><li>6 gallons/flush; 1.3 g/f </li></ul><ul><li>Faucet : Regular = 5 g/m; </li></ul><ul><li>Low-flow = 1.5 g/m </li></ul>
  6. 6. Direct Water Use (cont.) <ul><li>Another activity that uses a </li></ul><ul><li>tremendous amount of direct </li></ul><ul><li>water: lawn & garden watering </li></ul><ul><li>It takes 330 gallons of water </li></ul><ul><li>to irrigate a 1,000 sq. foot </li></ul><ul><li>tract of land with ½ inch </li></ul><ul><li>of water. </li></ul>
  7. 7. Virtual Water (Indirect Water Use) <ul><li>You may not drink, feel or see this water, but it makes up the great majority of your water footprint. </li></ul><ul><li>The Calculator takes into account not only the water used in your home, but also the water used to produce the food you eat and the products you buy. </li></ul>
  8. 8. Virtual Water (Indirect Water use) <ul><li>Your water footprint includes other factors, such as water used to cool power plants that provide your electricity, and water saved when you recycle. </li></ul>
  9. 9. Indirect Water Use (cont.) <ul><li>Water is used for cooling </li></ul><ul><li>purposes at thermoelectric </li></ul><ul><li>power plants (e.g., coal fired </li></ul><ul><li>and nuclear) </li></ul><ul><li>Water-Energy nexus for </li></ul><ul><li>thermoelectricity production </li></ul><ul><li>Sustainable energy </li></ul><ul><li>production like solar, wind, </li></ul><ul><li>and geothermal use virtually </li></ul><ul><li>no water. </li></ul>
  10. 10. Indirect Water Use (cont.) <ul><li>Not only is water used directly </li></ul><ul><li>to wash a car ( 150 g/wash), </li></ul><ul><li>But water is also necessary </li></ul><ul><li>to produce automobile </li></ul><ul><li>gasoline indirectly </li></ul><ul><li>(i.e., debris flush during drilling, </li></ul><ul><li>oil refining, machinery cooling). </li></ul>
  11. 11. Indirect Water Use (cont.) <ul><li>A person’s diet is generally </li></ul><ul><li>the greatest water use </li></ul><ul><li>component in his or her life </li></ul><ul><li>Avg. Am. (3-5 servings </li></ul><ul><li>meat/day) = </li></ul><ul><li>1,052 gallons/day </li></ul><ul><li>Vegetarian = 516 g/d </li></ul><ul><li>Vegan = 446 g/d </li></ul>
  12. 12. Breakdown of Water Use in USA <ul><li>Thermoelectric power : 48% </li></ul><ul><li>Irrigation : 34% </li></ul><ul><li>Public Supply : 11% </li></ul><ul><li>Industry : 5% </li></ul><ul><li>Domestic (self-supplied): </li></ul><ul><li>Less than 1% </li></ul><ul><li>Mining : Less than 1% </li></ul><ul><li>Livestock, Aquaculture : </li></ul><ul><li>Less than 1% </li></ul>Source: USGS; Estimated Use of Water in the United States in 2000
  13. 13. If our home water use is relatively small, why conserve? <ul><li>(Virtual) Water is contained in almost everything we use and buy, so we use more water than it seems. </li></ul><ul><li>By being conservative with water, we become more water conscious in our own lives. </li></ul><ul><li>This can lead to a Conservation Ethic in society </li></ul><ul><li>(local to global) </li></ul>
  14. 14. If our home water use is relatively small, why conserve? (cont.) <ul><li>Helps to build a Water Constituency that is concerned about water issues in the U.S. and the world and one that cares about how water is used and where it flows. </li></ul><ul><li>Water Constituents can show the need for water conservation as both a common good for society, the natural environment, and business. </li></ul><ul><li>In this way citizens can consider and collectively decide who has rights to water and how that water is used and distributed water in a responsible manner. </li></ul>
  15. 15. Where to begin? Building a Water Constituency <ul><li>Find out the water quality of your local supply; check water quality report </li></ul><ul><li>Get interested in decisions made by your water authority; Where is your water going? Is the water use sensible? </li></ul><ul><li>Lobby local, state, and national officials to make water a priority and its use wise and efficient. </li></ul><ul><li>Educate people, especially children, on the severity of water issues. </li></ul><ul><li>Educational Curriculum, geared towards students from Kindergarten through High School, will be launched on the H 2 O Conserve website this Fall. </li></ul>
  16. 16. Conclusion: Starting at Home <ul><li>After taking the water calculator </li></ul><ul><li>assessment, your water </li></ul><ul><li>footprint and series of water </li></ul><ul><li>conservation tips are given. </li></ul><ul><li>Your individual and household </li></ul><ul><li>water use is calculated and tips </li></ul><ul><li>specific to your water use habits </li></ul><ul><li>offered with the option for them </li></ul><ul><li>to be emailed. </li></ul><ul><li>A “Tips” section also exists. </li></ul>
