    <subfield code="a">Water pollution and water stress is tremendous problem in the pastoral area of Somali region 
including Kebribeyah  Woreda. This study was made to assess the performance of  traditional
rain  water  harvesting  Birkas  as  a  source  of  domestic  and  livestock  water  supply  at 
Kebribeyah Woreda. For this study a total of 150 household questionnaires conducted and 15
water  samples  from  15  Birkas for water quality test were  analyzed from  selected  Lebeshek, 
Gerbe and Meregacho Kebeles.  The design and physical capacity  of the Birkas were  studied 
with  site  visits  and  documents.  Temperature,  electric  conductivity,  pH,  turbidity,  total 
hardness,  total  dissolved  solid,  alkalinity,  nitrate  and  total  coliform  was  analyzed  to 
characterize the water. 
80%  of  the  Lebeshek,  80%  of  the  Gerbe  and  100%  of  the  Meregacho  of  the  measured 
samples  pH  values  satisfies  WHO  standards.  40%,  20%  and  20%  of  the  sample  turbidity 
from  Lebeshek,  Gerbe  and  Meregacho  respectively  satisfied  the  WHO  standards  however, 
none  of  the  samples  were  qualified  the  WHO  standard  for  total  coliform.  The  rest  of  the 
parameters are  within  the permissible limit of WHO  standards for drinking water  standard.
The  conducted  survey  indicated  the  highest  proportion  of  water  supply  consumed  by  the 
livestock.    Little  sense  of  ownership  and  responsibility  among  the  community  towards  the 
Birka,  luck  of  frequent  maintenance  and  water  treatment  were  the  major  problem.  With 
regard to the quantity of water and quality loss, water loss due to evaporation, sedimentation, 
crack (seepage)  and poor management condition was aggravating the problem of the water 
shortage in the area.
These  preliminary  results  can  be  useful  for  relevant  stakeholders  to  take  the  necessary
measures  when designing, rehabilitating, managing Birkas  in the area. The involvement of 
community is of paramount importance for sustainability.</subfield>
