Reuse of treated waste water for agriculture enables fresh water to be exchanged for more economically and socially valuable purposes, while providing farmers with reliable and nutrient-rich water. This exchange also has potential environmental benefits, reducing the release of waste water effluent downstream and allowing the assimilation of its nutrients into the soil. If wastewater reuse was rejecting, the option could be costly in such situations. The aim of this study is to identify the suitability of primary treated sewage water alone or mixed with different rates of Nile water and their effects on soil properties and grown plants. So, field experiments with Randomized complete Block design were conducted in winter seasons of 2011/2012 for flax crop, to study the effect of different water irrigation quality on the fiber yield and characters of sakha 2 flax cultivar at Balaks sewage water station,El-Qalioubia Governorate, Egypt. Results revealed that 100% sewage water recorded highest mean values of most flax characters such as total length, technical length, , No. of capsule / plant, No. of seeds / capsule, No. of benches / plant, fiber length and Iodine values, fiber yield per Fadden, fiber length, long fiber percentage and fiber fineness. On contrary, using 100 % swage water caused significant decrease on fiber strength compared with those irrigated with 100% Nile water. The highest values of seeds yield, straw yield, fiber yield, weight of 1000 seeds, oil yield, fiber (%) and seed oil (%) were observed with irrigation 100% sewage water.
