The present study was conducted in the Al-Beida, AL-Gabal AL-Akhdar region, Libya and carried out during the period from April 2013 to March 2015, on open broiler houses. The objective of this study was to predict the water consumption for broiler house. Water consumption must be precisely predicted in order to extreme supply the water as a vital and important factor for the living. A large proportion to the bird weight consists of  bird's water consumption and also  as  a  measure  of  bird  health  and welfare. In this study feed type and broilers (Spanish) are constant during this study. The average daily water consumption of ten flocks of broiler chickens was measured (average = 8,000 birds/flock), and the weekly feed consumption and broiler live body weight  was measured. The results showed that the water consumption for one broiler (in grams) was the twice in comparison with feed consumption. The results show that also the mean water consumption for one bird during its flock duration (49 days) was (8.48 L.). On the other hand, it can be seen linear relationship between daily broiler water consumption (W.C) (ml) and its age (A) (days), and this relationship submitted to the following equation: W.C (ml) = 7.16 A (days)                    (R² =0.98)
