ABSTRACT Surface irrigation is used to apply food processing wastewater. A newly developed flow-through infiltrometer was developed to measure the influence of wastewater quality on intiltration and irrigation performance. Steady infiltration rate decreased with increased loading of BOD and TS of tomato processing wastewater. Using a hydraulic model to simulate irrigation performance, it was shown that ignoring the decline in intiltration with increased loading and using the unadjusted infiltration function reduced predicted application efficiency 23%. Surface irrigation system design should therefore include the effect of wastewater quality.
