Friday Photo (43) - Latrine

TANZANIA: LATRINE
This newly constructed latrine at a school in Tanzania means that school children can  use a safe, clean sanitary facility - and waste can be prevented from entering drinking water.

Friday Photo (24) - Rural Water Supply in Tanzania

TANZANIA: UNPROTECTED WATER SOURCE
This photo, taken in the Kagera Region of Tanzania, highlights a case where communities had been given limited support to protect their water supply - resulting in a large pool of stagnant water, attracting flies and animals.

TANZANIA: Ol Doinyo Lengai From the EGU Open Access Image Repository, the Ol Doinyo Lengai volcano in Tanzania is special and unique due it being the only active volcano to produce natrocarbonatite lava, rather than the common silicate lavas.

Friday Photo (14) - Fancy Drinking This?

TANZANIA: POOR QUALITY WATER SOURCE 
Fancy drinking this? How about washing in it, or cooking with it? For some communities in the Kagera Region of Tanzania, and many other places, they have very little choice. GfGD founder, Joel Gill, was involved in supervising the initial surveying for a clean water source in this locality.

GfGD Archive: Photos from Tanzania

This time last year I'd just got back from Tanzania, where I was working on a small-scale water programme. Over the past year we've published a number of photos relating to the geology and water resources in the Kagera Region of Tanzania, where I was based.

Friday Photo (10) - Small-Scale Mining (Tanzania)

We are well into our Friday Photo series, highlighting the work of geologists and the impacts of their work. Don't forget - if you have a photo you want to share - contact GfGD.

Friday Photo (5) - Spring Protection Schemes

TANZANIA: SPRING PROTECTION SCHEMES
A series of spring protection schemes, highlighting some of the good and bad aspects of construction:
TOP: Main spring is covered however there is poor drainage of surface water.
MIDDLE: Failure to cover the water means this is not really a spring 'protection' scheme. Poor drainage also.
BOTTOM: Main spring is covered and there is good drainage. This is a high quality construction.

TANZANIA: SUCCESSFUL & SUSTAINABLE DEEP BOREHOLE -
This water supply was built at least 30 years ago and is still working well, thanks to good management and maintenance by the local community and caretaker (pictured).

Photos: Surveying for a Shallow Well

Initial Reconnaisance - examining the general location of the village, soil & rock exposures, existing water sources etc   



Discussion - An important part of the surveying process is to talk with people in the village to get their views and opinions, learn from them, ask for their help, support and contributions to the project.



Hand Auger - Augering down through the ground, to examine the soil structure.



Examination of the soil to assess its properties (such as permeability etc),



1.5m of soil, into low permeability clays. In this location the clay persisted for several metres making the site unsuitable for a shallow well.
