摘要：Background and Objective:The dairy industry consumes great amounts of water and generates large quantities of wastewater. The study problem is the lack of available water resources which reflected in decreased average per capita water. The main objective of this study was to study the efficiency of water use in the production units, estimate the cash yield of the water unit and finally study the factors that affect them. Materials and Methods:Data were analyzed using Statistical Package for Social Sciences (SPSS) version 16. Quantitative data were presented as Means±SD. The independent sample- ANOVA was used with two-way analysis of variance, with Post-hoc (LSD) test was used to analyze mean difference. Probability values (P) of less than 0.05 were regarded as statistically significant. Results:The most important results of the study suggested to the low average per capita average annual attrition rate of about 1.29% and rising share of water resources industry with a growth rate of approximately 15.1% during the study period have been measuring the significance differences between the sample in the water-use efficiency, proven statistical model significant at level p<0.05. Also, suggest the disparity in the percentage of the cost of employing and run water to an average of about 5% of total operating costs, as well as indicate low efficiency rate. Conclusion:The study concluded that a clear plan Inspection Department on how to deal with these facilities over the long term and anaerobic biological treatment in processing the high organic content industrial pollutants.
