Paper Details

Mankind is currently confronted with one of the greatest challenges in its history, thus how to adequatelyuse its limited freshwater resources. In this context, the challenge is the shortage of water sources, which led to the use ofwastewater for agriculture purposes. The reuse of treated wastewater for irrigation is a practical solution to overcomewater scarcity, especially in arid and semiarid regions. However, there are several potential environmental and healthrisks associated with this practices. Many cities and districts are struggling to balance water use among municipal,industrial, agricultural, and recreational users. The population increase has not only increased the fresh water demandbut also increased the volume of waste water generated. Sewage, often untreated, is used to irrigate 10% of the world’scrops, according to the first ever global survey of waste water irrigation. However, many farmers, especially those inurban areas, use sewage because it is free and abundant, even during droughts, and, being full of nitrates andphosphates, acts as an effective fertilizer. In addition, wastewater is a valuable source for plant nutrients and organicmatter needed for maintaining fertility and productivity of arid soils. Domestic wastewater contains essential plantnutrients such as N, P, K and micronutrients which are beneficial for plants growth. The objectives of this study were toevaluate the changes in soil parameters after discharging domestic wastewater on soil.The paper aims to investigate the impact of domestic waste water for irrigation purpose on soil fertility. Now-a-days dueto the increasing the population, the demand of water has increased considerably resulting in the generation of moredomestic wastewater. The use of the domestic wastewater improves the physicochemical properties of the soil ascompared to the application of ground water. Domestic wastewater helps in better crop growth with increased fertilitystatus of the soil. Application of domestic water increases total N, P, K and organic carbon content of soil & therebyincreases the yield of crops compared to irrigation with ground water.
