EWB by the Numbers 2001: EWB-USA founded 300 chapters 12,000 members 280 Projects in over 40 countries 2004: EWB-NEU founded 2005: EWB-NEU travels on first trip 5 successful trips 118: Population of Los Planes
6
Los Planes: Spring 2006 The Assessment Main water source from a stream 15 min. away A few houses receive a trickle for about 1 hour each day Both sources contaminated with coliforms
7
Los Planes: Spring 2006 The Assessment Water sample testing Traditional surveying works well for elevations –Establish benchmark Sub-meter accurate GPS is quick –Don’t rely on elevations
8
Los Planes: Spring 2006 The Assessment On average 6 people live in each home Villagers report going without food 2-3 days a week Very little variety in diet Malnutrition is a major problem
9
Los Planes: Winter 2007 ACTS Assessment Follow-up Keily Marisela Vieda 19mo female 14lbs. –Diagnosed with severe malnutrition, poor growth, language delay and lower extremity flaccidity Many Villagers in poor health Report if they had more reliable water source they could grow a variety of vegetables

Important Lessons Learned Consider arriving on a Thursday to allow shopping on Friday. Allow twice as much time as you think you'll need for everything. Allow more if the task involves conversation or other human interactions. Have another person check your work or calculations, especially if it is after 10:00 pm or before 6:00 AM. Bring large format pictures and drawings to show at the “kick off” meetings. Make lists of things to do and bring the night before. The most focused and productive meetings can occur while driving on bumpy roads before sunrise. The villagers are resourceful. And don’t need to be micromanaged. Use designs that feature easy construction. Always bring the PVC saw, duct tape, string and rope. The tree vice was crucial for working with GI
25
Do Not Touch Animals
26
Work With What You Have
27
Additional Lessons Learned Don’t touch geckos, they may be scorpions. Avoid eye damage – wear sunglasses when riding in the back of the truck. Insects hurt at high velocities. Bolt cutters cut bolts, not cable. Buy more vegetables and canned fruit. Eat more vegetables and canned fruit. Always bring toilet paper in the field – Lempiras are not as absorbent.
28
Paying For It All All trips are paid for through fundraising Average cost is $10,000-15,000 depending on size and type of trip 50% is usually dedicated to airfare
29
Fundraising Donations –Engineering Companies –Grants –Family and Friends CIVILized Solutions Smurfit-Stone Container Co.
