Scott, C. A.; Zarazâ€¢a, J. A.; Levine, G. (Comp.) 2000. Urban wastewater reuse for crop production in the water-short Guanajuato River Basin, Mexico. Colombo, Sri Lanka: IWMI. v, 34p. (IWMI Research Report 41) [doi: 10.3910/2009.047]
From a river-basin perspective, wastewater irrigation is an important form of water and nutrient reuse; however, there are important water quality, environmental, and public health considerations. This report explores the advantages and risks of urban wastewater reuse for crop production in the water-short Guanajuato river-basin in west-central Mexico, and then by a selective literature review demonstrates how common this practice is worldwide. It also evaluates several alternative water-management scenarios through application of the Interactive River Aquifer Simulation (IRAS) model, developed by Cornell University and Resource Planning Associates.
