To investigate the beneficial impacts of wastewater on soil properties, we conducted an experiment
in the lysimeter by measuring certain features essentially related to soil characteristics. Our objectives in this
study were (i) the wastewater infiltration by soil and (ii) the effect of wastewater on soil properties. In this
experiment, 9 lysimeter were used, 1, 2 and 3 lysimeters irrigated by domestic wastewater. Then, first drainage
water accumulated from these lysimeters and 4, 5 and 6 lysimeters irrigated by this water and secondary
drainage water accumulated from upon lysimeters. In order to comparison soil properties, 7, 8 and 9 lysimeters
irrigated by normal water and finally, soil and water properties analyzed in each stage. The results showed that
soil could filtering the wastewater and reduced BOD5 and COD of wastewater sorely. Also, irrigation with
wastewater increased nutritive elements in soil that can be source of nutrition for plants. Our findings may give
applicable advice to commercial farmers and agricultural researchers for management and proper use of water.
