In order to evaluate drip zone configurations with respect to distribution uniformity, a field-scale experiment was set up and three drip tubing products were tested in different dosing and operation schemes. Three factors of wastewater drip system design were tested. System operation pressure (138 kPa and 276 kPa); different pressure control schemes (usage of pressure regulator/recirculation valve/continuous flushing/intermittent flushing); and supply line length (7.6 m, 15.2 m and 30.4 m) were evaluated to compare their influence on water application uniformity. It was concluded that, for Geoflow PC and NPC products, among all three factors, system operational pressure has the greatest effect on drip system application uniformity; supply line length has the least influence. For Netafim PC tubing, pressure control scheme has the greatest effect on drip system application uniformity; supply line length has the least influence. The optimal combination of the three factors could save more than 10 minutes of dosing time to meet the required distribution application uniformity. Drip zone dose time under required application uniformity was computed on the layout of different runs per lateral.
