The aim of this study was the evaluation of Karoun west agro-industries water quality with attitude of their reuse. The annual water quality parameters included average of four drains in periods of 2014-2015 were evaluated. Wilcox principles, used to evaluate each drain water quality to reuse. According to the results, Dehkhoda agro-industry with 25000 ha area had the most drainage EC between all plans. After that, the agro-industries of Amirkabir with 15000 ha area and Mirza-kouchak-khan with 14000 ha area had the most drainage EC, respectively. Based on Wilcox principles, the drainage of all studied drains had unsuitable quality (between 6.8 to 10.6 dS/m) based on EC evaluation and placed on the C4 group. Then, based on EC and SAR evaluations, the sugarcane drains quality of (Amirkabir and Dehkhoda agro-industries) was 6846.67 ds/m and SAR range was 1.03. The average EC obtained 15015 mhos/cm in the railway bridge and also the average SAR was 2.18 in this drain. EC and SAR obtained 10620 mhos/cm and 1.66 in Shahid Maleki drainage in 2014. Also in Shahid Ahmadian drainage there are 8000 mhos/cm and 1.88, respectively. . Therefore, in terms of salinity (EC) and (SAR), sugarcane canal drainage quality (Amirkabir Agro-industry and Dehkhoda Agro-industry) and Shahid Ahmadian fish farming drain in C4S2 classification. The drains quality of Shahid Maleki fish farming and Railway Bridge had C4S3 rank. Finally, the suggested practical technique for use of Karoun west regions drainage was their combination with the fresh water such as Karoun River water or the water of other Rivers in Khuzestan province to obtain better quality.
