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
