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

Develop a software tool to design water distribution systems 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

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

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.

Background Insufficient funding Key Obstacles 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

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

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 Dale’s Talking Notes…. Ok let’s see. Background has been presented, semester goals have been outlined, team has been introduced and the organization we are working with has been identified. I’m going to present the details of what the engineers in APP are currently using to design these systems (slide 7), outline what was accomplished last semester (slide 8) and then give the details of how we are breaking up the problem (work plan – 9,10 and 11), project schedule (12) and then picture again(13)? Possible script: Now that you all have a general understanding of the current situation of water supply in Honduras, I’d like to give you a brief overview of the current design tools used by Agua Para el Pueblo engineers. Survey data is usually taken via a theodolite and a stadia rod and then the data are analyzed and the design completed using Microsoft excel. This approach is functional, but several improvements can be made. (The current spreadsheets are not very flexible and there are some technical design improvements that can improve the robustness of the designs and extend the life of the project.

Spring 2003 EWF Last semester team goals: Accomplishments: 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 Our work this year is a continuation of the work done by last Spring’s EWF water supply group and a brief overview of what was done last semester is necessary before outlining what we intend to complete this semester. Last semester’s goal was to “blah blah blah blah” with the focus on user-friendly, easily adaptable and to standardize the design. The group made significant progress in these areas but there is still work to be done on the spreadsheet. The skeleton tool they created still has some algorithms that need polishing and/or fixing and the tool needs to be translated into Spanish.

Fall 2003 Work Plan Research Review spreadsheets GPS and altimeter 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

Project Schedule

Gravity Fed Water Supply Design Fall 2003 Work Plan Inputs Survey data Altimeter data Population data Outputs Pipeline dimensions Locations of pressure breaks and air release valve Tank size Spring box Air release valves Distribution Tank Does this picture need to be in here again? Any ideas on what I’m supposed to be sayin’ here?

Local High Points Elevation vs. Hydraulic Grade Line

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

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

Team Organization Rural Water Supply Team Organization Project Leader Dr. Monroe Weber-Shirk Team Leader *Kendra Skopp Technical Assignments Non-Technical Assignments EPANET *Peter Burns General Spreadsheet Update and Improvement Christopher Boone Peter Burns Amy Grove Andrea Gruber *Dale Meck GPS Incorporation *Christopher Boone Secretary *Amy Grove Project Documentation *Andrea Gruber Sima Thakkar City-Planner (Geographical/Political Context) *Sima Thakkar Liaison to Partner Org. *Dr. Monroe Weber-Shirk *Group Leaders To accomplish this task we have divided our project into two areas technical and non-technical assignments. Our hope is that this will encourage progress while maintaining our goal of appropriate technology. We voted on a group leader, but the rest of the organization developed out of our team member’s natural interests and strengths.

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)

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

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
