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
