Notes de l'éditeur
- India and Tuscon http://thinkchangeindia.wordpress.com/2008/06/06/putting-laws-into-practice-the-case-of-rainwater-harvesting/, http://www.awwa.org/Resources/WaterWiserNewsDetail.cfm?ItemNumber=42023 vs Colorado and Utah -http://www.ksl.com/?nid=148&sid=4001252, http://www.rainwatercollecting.com/blog/?p=56-In Bolivia, 2000, a 17 year old boy killed and many injuries as wellhttp://www.foodandwaterwatch.org/water/private-vs-public/corporations/Bechtel
- These aren’t always the case, but often are. Have the audience populate this list.What is different between the water that falls and the water that runs off?
- Most images from http://www.appropedia.org/Rainwater

- Here is a spreadsheet for sizing - https://spreadsheets.google.com/ccc?key=0AjTvqXcCy42EcFVhbWxnY2s2VDdjV0lsNzVvbnRVTEE&hl=en
- Feel free to then multiply by a roof efficiency factor. This rule of thumb gives us 3000 gallons without the efficiency factor and 2400 gallons with the efficiency factor… pretty darn close to 2500 gallons.
- Someone wants it
- A partnership
- Research
- A student builds it…. Student is found through Appropedia
- Omar is pursuing a bachelor's degree in environmental resource engineering at HSU, concentrating in water quality issues. Omar is interested in graywater systems for the recycling ability they offer for water, an increasingly limited resource.
- Steven J. Addison has worked in the environmental conservation field work since he first feel in love with the Klamath River in the mid 90s. As an Environmental Resource Engineering major at Humboldt State University Steven has had a chance to continue his learning and understanding of natural processes, and hopes to one day contribute to writing future policies effecting water use on a national level.
