  3. Abstract:
  4. The hydraulic performances of drain pipes are very important in drainage projects and systems. Usually these pipes are used in a saturated soil to decrease the water table to a favorable level or, drain the excess water. However, drain pipes can be used in a water or wastewater tank for different purposes such as selective withdrawal. There are not much published documents on the performance of drain pipes in submerged situations. Therefore, the aim of this study was to examine the performance of drain pipe in a submerged tank. For this, a horizontal pipe of 26.5 mm inner diameter, 5 meter long with 48 circular drain inlets of 10 mm diameter at equal distances along the pipe have been tested in a submerged situation. The drain inlet holes have been used as different combination of opening under four different water head. The pressure variations along the drain pipe have been recorded using piezometers. The results show that not only the number of the inlet holes influence the discharge into the pipe, the position of the holes are influential and very important for selective withdrawal. Finally the results of the influence of these variables on the discharge into the drain pipe are presented as graphs and design suggestions
