Presentation Outline: 

Presentation Outline Introduction to EWB-USA Tanzania Project Background Project Implementation Next Steps

Slide3: 

Engineers Without Borders-USA

The Beginning: 

The Beginning EWB-USA started in 2000 with professor Bernard Amadei and a group of students from CU Boulder on a trip to Belize They recognized the role engineers need to play in addressing the world’s needs

EWB-USA Vision: 

EWB-USA Vision A world where all people have access to adequate sanitation, safe drinking water, and the resources to meet their needs

EWB-USA’s Mission: 

EWB-USA’s Mission Low Tech, High Impact Partner with disadvantaged communities and empower them to improve their quality of life Implement environmentally sustainable, equitable, and economical engineering projects Develop internationally responsible engineers and engineering students

Slide7: 

Our Projects: Projects in 2006 – 120 (95 in 2005) Demand exceeds delivery capacity Projects in 40 Countries Our Sponsors: Philanthropic Groups, inc Rotary (10%) Energy and Engineering organizations, ASCE, ASME, ASFE US EPA, United Nations, USAID, State CH2M Hill, Chevron, others Our Organization: Nine Administrative Staff Based in Longmont, CO Large Volunteer Tech Advisory Committee

EWB-San Francisco Professionals: 

EWB-San Francisco Professionals SF Professional Chapter of EWB-USA Carry out the mission of the organization 4 Projects and one R&D Team Tanzania, Haiti, Sri Lanka, India, Sudan Hold events and fundraisers to interact with and bring awareness to community Partner with other local organizations

Slide9: 

Water and Health Improvement Project Ngelenge, Tanzania EWB-SFP and NGEDEA

Southwestern Corner of Tanzania: 

NGELENGE Southwestern Corner of Tanzania

An Area w/ Natural Resources: 

An Area w/ Natural Resources

Ngelenge Background: 

Ngelenge Background Ngelenge is in SW Tanzania, where the Ruhuhu River meets Lake Nyasa Population of ~2,500 people in ~350 households Lacks basic services including: Adequate and safe water supply Health and higher education services Transportation Electricity Challenges with agriculture, food security, and income generation

Slide13: 

Nearest health facility 7km (by foot) Not enough medicine Limited services Almost no irrigation At the mercy of droughts and floods Small cash crop harvests Fish populations decreasing

Slide14: 

Ngelenge Development Association (NGEDEA) NGEDEA started by villagers in 2003 Mission is village development in Ngelenge and surrounding area Officially registered as Tanzanian NGO Main office in Ngelenge with a branch in Dar es Salaam

Slide15: 

Project History 2004 – Project Begins January 2005, Visit by Lorrie Johnson Water quality testing May 2005, Visit by Maggie Montgomery Assessment and prioritization of village needs September 2005, Official Site Assessment, 5 member team Surveys of agriculture, economics and water quality Hydrogeologic study Brought materials for health dispensary Participatory methods workshops

Slide16: 

An Organized Community Grassroots development organization Even a student chapter Water committees for each well Three women's groups Fishing group Farmers group However… Most villagers only have primary school education Have very limited access to tools or materials Very limited income generation

Slide17: 

Village Priorities Short Term: Complete health dispensary Deep well with clean water Irrigation Longer Term: Water distribution system Solar on health dispensary Health education Expanded irrigation

Slide18: 

Implementation Trip August, 2006

Slide19: 

Volunteer Teams Team 1 - 6 Volunteers: 2 Mechanical Engineers 1 Environmental Engineer 2 Peace Corps Volunteers (recently completed) 1 UC Berkeley Grad Student Team 2 - 6 Volunteers: 2 Environmental Engineers 1 Chemical Engineer 2 Software Engineers 1 Yale Engineering Grad Student Each team spent 10 days in the village

Slide20: 

Implementation Trip Goals Health dispensary follow up Drill 50m well Build slow sand filter Administer health survey Provide solar power training Survey agricultural land Lay out next steps

Slide21: 

Travel to Ngelenge Human-powered ferry over river Minibus from Songea to Ngelenge 15 hr bus ride from Dar es Salaam to Songea 32 hrs flying 32 hr flying SFO to DAR

Slide22: 

Health Dispensary

Slide23: 

Health Dispensary Dispensary building is nearing completion Visited district government to discuss staffing of dispensary Staff housing and latrines needed before staff can be assigned NGEDEA and EWB working together on financing Plan is to have dispensary running by July 2007

Slide24: 

Water and Well Drilling

Slide25: 

Average water use is 40L/day (you use approximately 400 L/day) Three shallow wells with hand pump built by NGO Concern International in 1997 Bad water quality in two wells One well runs dry in the dry season One clean well Villagers far from wells drink contaminated lake and river water

Well Drilling: 

Well Drilling Well site chosen by NGEDEA based on hydrogeologic study Hired Tanzanian well drilling contractor: Hydrotech Very competent Villagers contributed labor Dug pits for mud Gathered gravel and water

Well Drilling: 

Well Drilling Soil samples Mud Rotary Drilling Planned to drill one bore hole, 50m deep Drilled three holes with varying results Three sub-villages One hole “on the house” NGEDEA and Villagers did an amazing job wrapping up the project Cased third hole Repaired old hand pump

Final Well Results – Great News!: 

Final Well Results – Great News! Afridev handpump NIRA handpump All wells approximately 50m deep Water quality test will be done soon CCM well has capability to feed distribution system

Water Distribution System: 

Water Distribution System Looking into appropriate pumping technology options Solar Wind Manual Determining system installation and maintenance costs Village ownership and maintenance “Culture of Maintenance” Village raising estimated 10% of cost

Slide30: 

Slow Sand Water Filtration

Slow Sand Water Filter: 

Slow Sand Water Filter Residents of Faulklands sub-village 4 km from wells River and lake water are main drinking water sources Both are very contaminated Slow Sand Filtration selected as trial method of water filtration Can be made from local materials Economical (needs work) Scaleable

Slide32: 

Slow Sand Water Filter Drilling the Filter Body Washing Built demonstration unit in the Faulklands Provides clean water for 100 people Materials brought from USA, but equivalents sourced in TZ Goals See if materials available can build a working filter Get feedback from village to make filter more suitable

Slide33: 

Slow Sand Water Filter Sieving Gravel Sieving Sand

Slide34: 

Water Filter - The Inevitable Setbacks Cement filter foundation a little leaky Contaminated Barrels Resourceful Tubing Connections

Slow Sand Water Filter: 

Slow Sand Water Filter Product Tank Filter Feed Tank Settling Tank

Falklands Community: 

Falklands Community Sustainability: measured by long-term performance (in dry and wet seasons) and maintenance issues

Slide37: 

Education and Information Gathering

Slide38: 

Solar Power PV system planned for dispensary once it is staffed Held workshops to train villagers Working with local solar contractors, organizational and government Need to ensure system will be maintainable

Slide39: 

Health Survey Survey on health and water usage Administered to 147 women with children under 5 Developed by EWB Volunteer, PhD epidemiologist Purpose was to obtain detailed baseline information on current village practices Learned invaluable lessons regarding local customs and working with translators.

Women-Focused Health Workshops: 

Women-Focused Health Workshops Fecal coliform transmission routes Blocking mechanisms for contamination Workshop based on WHO PHAST Method

Agriculture: 

Agriculture Planning for pilot drip irrigation system in 2007 Partnering with International Development Enterprises (IDE) Surveyed and selected areas for agriculture pilot project Met with women’s groups Proposed irrigation system and received feedback Images courtesy of IDE

Next Steps: 

Next Steps Review drilling report and write implementation trip report Design and implement agricultural pilot study for drip irrigation system Monitor filter performance and receive villager feedback on design Develop cost estimates and preliminary design water distribution system Begin tender process with Tanzanian solar contractors Fundraising Grant writing Partnerships w/ Rotary Chapters and Rotary International

How Can Others Get Involved: 

How Can Others Get Involved Provide resources and expertise Training materials Mentorship Provide project funding Grants to EWB-SFP
