Kendra SkoppSima Thakkar
Advisor: Dr. Weber Shirk
Fall 2003
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
PipeStorage
Tank
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 Institutional incapacity to construct and maintain
rural water supply systems Shift towards decentralization of water resource
management to community levelKey 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
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
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

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
