A description of the market challenges and opportunities in water supply in Tanzania and our services to make your project a successful reality.

1. Water Development Opportunities in
Tanzania and East Africa
Quality and services to get the job done
Ground+Water Tanzania, Ltd.

2. A comparison of Scale
• Scale
comparison:
• 2 Californias
side by side

3. Tanzania has
water challenges…
Dodoma: High and dry –
• Savanna-like landscape
• Highly oxidized, weathered soil over East
African shield rocks, south end of a branch
of the Great Rift System

4. Challenging: Half the country receives
<800 mm (31 in) of rainfall per year,
with central and western Tanzania dry
up to 7 months per year. The rains are
increasingly erratic.

5. Tanzania is a land of
contrasts…
Kilimanjaro region is high, with
volcanic soils, and has
generally abundant water

6. But the source is at risk:
climate and deforestation
UNEP and NASA

7. Fluorosis • Common in mountainous
Arusha due to geology
• A big risk to teeth and
bones, and avoiding it is
hard
• Requires technical water
treatment to remove

8. Underutilized (but hardly infinite)
ground water resources
Takes expertise to
find and optimize

9. Remote and
Rural and also
Urban and
Cosmopolitan

10. Land of contrasts: Great, cheap
cell service where there is no
water

11. In places: Aging
infrastructure, poor
management, donor
dependency

12. The work of daily life is hard…

13. Digging for water

14. Pressure:
Deforestation, degrading
grasslands, resource
development

15. You may be working to supply
people with water, but you
wonder “How to do this
effectively?”

16. How to do water development:
One thing – not a place for little
drills & amateur drillers
Dodoma: Ground water is 100 m
deep and the aquifer is a jumble
of shield rock, ancient volcanic
ejecta, and alluvial deposits

17. The hydrogeology can
be difficult:
Weathered granite in Singida

18. Distance, remoteness are
features of working in rural,
inland Tanzania

19. So where to start? What to do?
Who is
familiar
with the
situation?
Get help…

20. Tanzania has an energetic
and cosmopolitan business
and professional class

21. Ndiyo!
Yup!
And long, strong Tanzanian-
American ties: Which leads to
deeper collaboration
I have my
credentials,
we should
work
together
We have expertise
and needs: We
should work
together

22. • Stuart Smith, long-experienced
American hydrogeologist and
microbiologist and businessman
• Naftal J. Mandi, MPH and MBA,
Tanzanian teacher and entrepreneur
So we are working together:
The G+WT partners:

23. Some needs we serve ….
• Finding finances/grant-writing, project
coordination, financial responsibility
• Training
• Inspection: See it’s done right
• Professional services: The geophysics,
specifications, well testing, borehole
inspection
• “Turn-key” – we’ll make sure the
project is completed
• Supplying better water equipment

24. We consult with and support
our colleagues in country
• Water Ministry
• Area professionals such as these
• Improving university capacity
• Local well drilling and water system
operation training
• Centers of excellence to build on

25. G+WT employs local
professionals and
technical resources,
such as
hydrogeologists and
geophysicists

26. Borehole Surveys Reveal…

27. Some projects we are involved in
Partnering together with all
sorts of sincere and skilled
people…

28. Water for hospital, bottling plant (income
generation), and surrounding community
Dodoma Christian Medical Centre

29. • Pumped clay in the
rainy season
• Excessive nitrates
• Not enough grout
Consulting on
Bottling Plant Well

30. Locating better well
equipment and advising on
choices for better service

31. Mlenga well-
siting study
(Dodoma)

32. A fracture zone, enhanced erosion
creates a small canyon, and …

33. … the fractures are a source of water

34. Mlenga well-
siting study
(Dodoma)
• Performed by
Dodoma hydro E.B.
Mcharo
• Found options at
site previously
called “hopeless”

35. Drilling was commisioned

36. No pressure at all …

37. Major water
strike at 125-
128 meters
And it was
good

38. Completed with a 25 m3 tank,
pump and control house and
solar powered well pump

39. Dedicated in February 2016

40. Nothing is easy …

41. Mzogole, Bahi District, Dodoma
• Advising donors on best technical
options
• Collecting information
• Advising village on water
management

42. A failed wind pump means
people are back to digging
for water

43. Borehole inspection and
capacity testing to size a
modern pump

44. Aya Secondary School
• Existing (2004)
borehole has never
been right
• Frequent pump
burnout due to poor
choices and use
• Documentation of
existing borehole,
adjustment of pumping

45. Siting a new borehole
to be drilled

46. Moshi East –
Area of
interest
Uchira Parish
St. James
Mbokomu

47. St James Seminary, Karangu:
High quality secondary
education for boys

48. St. James had a well…

49. Out of service since mid-1990s,
pump out… unprotected
Water supply was overwhelmed
regional piped water system.

50. Money raised and drilling begins
Advising donors,
seeking technical
solutions

51. Elevated tanks and power
connection finish the job supplying
plenty of water, securely

52. Uchira village,
near Moshi
Advising donors:
able to restore a
destroyed well

53. A good result
She has good
water again in
the dispensary
and can
improve the
sanitation

54. Kilatiti Secondary School

55. Training: Introduction to Well
and Wellfield Performance
Maintenance and Improvement
• First-ever seminar
of its type in
Tanzania
• Planned repeat in
interior location
• “Well”-received!

56. KondoaKaribuni!
