Abstract :
The increase in the population and industrialize live on the one hand and shortage of the drinkable water source and also need to much water and foods on the other hand has interested expert and specialist attentions in using of uncommon waters such as sewage and wastewater for agric water. It is evident that before irrigation carried out to sewages, we should to informed in respect of effects of the these waters on the plants by means of study and research, that we have operated a special management for optimum usage. for doing this, at one comparison design, where average gropes compared to control sample, we have studied effect of the irrigating to the domestic sewage and it is drain in the lies waiter method on final penetration rate in the farmland soil with the intention of this applied 15 numbers of the plastic lies miter to cylindrical shape that in them planted basil, Alfalfa and colza. After a measure final penetration rate in soils irrigated domestic wastewater and first and second rain, we found that average for final penetration in the colza lyesmiter soils irrigated by domestic sewage reduced to about -41%, it did reduce to -18% in the alfalfa limiter soils that were irrigating by first drainage and also it did reduce to -7% in the basil lyesmiter soils that it is irrigated second drain all of these results were as compared with control sample that irrigated by pit water.
