  "abstract": "Water pollution and water stress is tremendous problem in the pastoral area of Somali region \nincluding Kebribeyah  Woreda. This study was made to assess the performance of  traditional\nrain  water  harvesting  Birkas  as  a  source  of  domestic  and  livestock  water  supply  at \nKebribeyah Woreda. For this study a total of 150 household questionnaires conducted and 15\nwater  samples  from  15  Birkas for water quality test were  analyzed from  selected  Lebeshek, \nGerbe and Meregacho Kebeles.  The design and physical capacity  of the Birkas were  studied \nwith  site  visits  and  documents.  Temperature,  electric  conductivity,  pH,  turbidity,  total \nhardness,  total  dissolved  solid,  alkalinity,  nitrate  and  total  coliform  was  analyzed  to \ncharacterize the water. \n80%  of  the  Lebeshek,  80%  of  the  Gerbe  and  100%  of  the  Meregacho  of  the  measured \nsamples  pH  values  satisfies  WHO  standards.  40%,  20%  and  20%  of  the  sample  turbidity \nfrom  Lebeshek,  Gerbe  and  Meregacho  respectively  satisfied  the  WHO  standards  however, \nnone  of  the  samples  were  qualified  the  WHO  standard  for  total  coliform.  The  rest  of  the \nparameters are  within  the permissible limit of WHO  standards for drinking water  standard.\nThe  conducted  survey  indicated  the  highest  proportion  of  water  supply  consumed  by  the \nlivestock.    Little  sense  of  ownership  and  responsibility  among  the  community  towards  the \nBirka,  luck  of  frequent  maintenance  and  water  treatment  were  the  major  problem.  With \nregard to the quantity of water and quality loss, water loss due to evaporation, sedimentation, \ncrack (seepage)  and poor management condition was aggravating the problem of the water \nshortage in the area.\nThese  preliminary  results  can  be  useful  for  relevant  stakeholders  to  take  the  necessary\nmeasures  when designing, rehabilitating, managing Birkas  in the area. The involvement of \ncommunity is of paramount importance for sustainability.",
