Using GIS model to investigate sustainable irrigation techniques from wastewater

This work was done to investigate the distinguishing features of the flow of wastewater and the possibility of using it for irrigation purposes as a sustainable method in the future. The wastewater utilized in this case study was obtained from six different areas in Baghdad, Iraq, and was collected for analysis. A large number of wastewater samples have been collected from six distinct locations: al-Karkh project, south Rustomiya project, north Rustomiya project, Al–Rustomiya project, Al–Shaab project, and Hay al–Mustansiryia project. Several tests have been done to ensure the grey water validity for agricultural uses; these tests are PH, Cl, NO3, PO4, SO4 and phenols. Geographic Information System (GIS) was used to locate and present the results of the wastewater properties from the six projects in Baghdad. The results indicated that the wastewater contains a significant amount of phosphate, sulfate and nitrate, which is the fertilizer of the soil. Although this water cannot be utilized for irrigation directly, it must be primarily treated and then it can be used for irrigation safely in the future.
