More detailed design of smaller underground retention basins with filters, larger underground retention basins without filters and macadam basins.
The dimensioning of larger underground retention basins without filters and macadam basins now takes direct account of the calculated required flow detention, integrated in the box, with the option of specifying maximum outflow in the box. The length, width and depth of the basins are dimensioned and these are presented in the picture below the box indicating if the depth becomes too large. You may then need to increase the volume or outflow of the basin. Warning triangles appear if you go beyond normal recommendations.
The dimensioning of smaller underground retention basins with filters has basically no flow detention (such as drain inlet filters and oil separators which can also be specified in the box), but now the dimensions in the picture below the box are shown.
