The impact of a storm water storage tank outflow construction on its required volume is discussed. A dimensioning of the tank by a rational method applied for small sewerage systems is presented. For large systems, subroutines should be developed to take into consideration the construction details of complex storage tanks in the software enabling real time modelling of sewerage systems. Such subroutines can be tested under simple conditions using rational methods of sewerage modelling, including the approach described in the paper. In the example discussed here for two different positions of the sewer delivering to and collecting stormwater out of the tank both the tank required volume and the outflow as a function of time visibly depended on the sewer position. This was proofed for a rectangular chamber storage tank of the same bottom surface area. However, if the bottom surface area and the storage tank height were calculated in such a way to enable the same maximum value of an outflow from the tank for two different positions of the sewer both the tank volume and the outflow as a function of time were proved to be very similar. Concluding the tank volume depends visibly on the construction of outflow, but the height of the tank can be adjusted in such a way to keep the same maximum outflow for different details of the outflow construction. After this adjustment, the volume of the tank was proved to be almost independent of the construction of outflow from the tank.

讨论了雨水蓄水池流出结构对其所需容积的影响。介绍了一种适用于小型污水处理系统的合理方法确定水箱尺寸。对于大型系统，应开发子程序以考虑软件中复杂储罐的构造细节，从而实现污水系统的实时建模。这些子程序可以在简单的条件下使用合理的污水建模方法进行测试，包括本文中描述的方法。在此处讨论的示例中，下水道的两个不同位置将雨水输送到水箱并从水箱收集雨水，水箱所需的体积和作为时间函数的流出量明显取决于下水道位置。这适用于具有相同底表面积的矩形腔式储罐。然而，如果底表面积和储罐高度的计算方式能够使下水道的两个不同位置的储罐流出量的最大值相同，则储罐容积和流出量作为时间的函数都是事实证明非常相似。得出水箱容积明显取决于出水口的结构，但可以调整水箱的高度，以针对不同的出水口结构细节保持相同的最大出水量。经过这次调整，水箱的容积被证明几乎与水箱的流出结构无关。如果底表面积和储罐高度的计算方式使得下水道的两个不同位置的储罐流出量的最大值相同，则储罐容积和流出量都被证明是时间的函数非常相似。得出水箱容积明显取决于出水口的结构，但可以调整水箱的高度，以针对不同的出水口结构细节保持相同的最大出水量。经过这次调整，水箱的容积被证明几乎与水箱的流出结构无关。如果底表面积和储罐高度的计算方式使得下水道的两个不同位置的储罐流出量的最大值相同，则储罐容积和流出量都被证明是时间的函数非常相似。得出水箱容积明显取决于出水口的结构，但可以调整水箱的高度，以针对不同的出水口结构细节保持相同的最大出水量。经过这次调整，水箱的容积被证明几乎与水箱的流出结构无关。但是可以调整水箱的高度，以使流出结构的不同细节保持相同的最大流出量。经过这次调整，水箱的容积被证明几乎与水箱的流出结构无关。但是可以调整水箱的高度，以使流出结构的不同细节保持相同的最大流出量。经过这次调整，水箱的容积被证明几乎与水箱的流出结构无关。
