  1. EWF- Rural Water Supply Proposal Group Members: Christopher Boone Peter Burns Amy Grove Andrea Gruber Dale Meck Kendra Skopp Sima Thakkar Advisor: Dr. Weber Shirk Fall 2003

  2. This Semester’s Goal: • Develop a software tool to design water distribution systems • Gravity-fed systems • Rural communities in Honduras • Excel-based • Incorporates GPS and altimeter data • Outputs data to EPANET • Translated into Spanish

  3. Gravity Fed Water Supply Design Rural Village in Honduras Stream Storage Tank Pipe

  4. Background • Of the 510 million people residing in Latin America and the Caribbean, 76 million do not have access to safe water 53% of Honduran population lives in a rural area.

  5. Background • Insufficient funding • Institutional incapacity to construct and maintain rural water supply systems • Shift towards decentralization of water resource management to community level • Key Obstacles • Inappropriate design • Lack of technical expertise • Inadequate maintenance

  6. Partner Organization • Agua Para el Pueblo (APP) - Honduran Non-Governmental Organization (NGO) • Help developing communities obtain drinking water and adequate sanitation • Aid in design and construction of water distribution systems • Focus on community involvement

  7. Current APP Design Tool • Survey collection method • Theodolite and rod • Excel spreadsheet design • Functional but.... • Numerous worksheets • Nonflexible • Technical improvements • More robust designs • Longer project life

  8. Spring 2003 EWF • Last semester team goals: • spreadsheets that “provide technical assistance for the design of public, gravity driven water supply systems in small, rural villages in developing nations” • user-friendly • easily adaptable • standardized design • Accomplishments: • Skeleton Spreadsheet Tool • some algorithms still need polishing • tool needs to be translated into Spanish

  9. Fall 2003 Work Plan • Research • Honduran Politics - water boards & NGO’s • Appropriate Technology • Details of Pipeline Design • Review spreadsheets • APP designs • Spring 2003 design • GPS and altimeter • incorporate into design • Finish design tool • Create a Spanish user manual • Workshop in Honduras

  10. Fall 2003 Work Plan • Spreadsheet Work • Polish/fix algorithms • Incorporate EPANET • Incorporate GPS and altimeter survey data • Test • Debug • Translate

  11. Survey Data Acquisition Transmission System and Tank Design Distribution System Design Garmin GPS Unit EPAnet Network Microsoft Excel Spreadsheet Flow Specifications and Junction Locations Survey Data Excel VBA Script Excel VBA Script EPAnet Import Command EPAnet INP File Altimeter Excel VBA Script EPAnet Export Command List of needed materials for pricing (Not this Semester) Fall 2003 Work Plan

  12. Project Schedule

  13. Gravity Fed Water Supply Design Distribution Tank Spring box Air release valves Fall 2003 Work Plan Inputs Survey data Altimeter data Population data Outputs Pipeline dimensions Locations of pressure breaks and air release valve Tank size

  14. Local High Points • Elevation vs. Hydraulic Grade Line

  15. Elevation Precision • Difficulties • Large error with GPS unit • More precise technology too expensive

  16. Proposed Trip to Honduras • Education • See how water supply systems are designed and built • Examine the social and political context • Feedback on design tool • Instructional • Presentation of design tool • GPS and EPANET workshops • Determine ways EWF could be helpful in the future

  17. Rural Water Supply Team Organization Project Leader Dr. Monroe Weber-Shirk Team Leader *Kendra Skopp Technical Assignments Non-Technical Assignments EPANET *Peter Burns Secretary *Amy Grove City-Planner (Geographical/Political Context) *Sima Thakkar General Spreadsheet Update and Improvement Christopher Boone Peter Burns Amy Grove Andrea Gruber *Dale Meck GPS Incorporation *Christopher Boone Liaison to Partner Org. *Dr. Monroe Weber-Shirk Project Documentation *Andrea Gruber Sima Thakkar *Group Leaders Team Organization

  18. Resources • What we have: • 7 motivated, dedicated Cornell students • Cornell resources including: • Cornell Library System • Faculty advisor – Dr. Monroe Weber-Shirk • Access to computers and software programs • Lab space • Open lines of communication with: • Agua Para el Pueblo (APP)

  19. Resources • What we need: • GPS and precision altimeter • leave with APP in Honduras • Funding for workshop/educational trip

  20. Anticipated Benefits • A universal design tool to aid NGO’s • Reduction in design costs of gravity systems • Improved quality of life for members of rural, less-developed communities • Personal Benefits • Exposure for EWF • Real-life engineering application • Deeper understanding of relationship between technology the social change
