Land Drainage
Our solutions also enable reliable calculations of site drainage based on the standards DIN 1986-100, DIN EN 752, and DIN EN 12056.
Holistic Land Use Assessment
In addition to ensuring compliance with standards, our solutions also calculate a surface area balance based on all runoff-generating areas of the property. They determine the surface drainage for the entire property, taking into account the respective runoff coefficients and rainfall intensities according to the KOSTRA-DWD 2020 Atlas. These calculations are part of the documentation submitted to the municipality to demonstrate that the property’s drainage system complies with the provisions of the ordinance and can be approved. Available for Dendrit CALHYDRA and Dendrit STUDIO.

- Validation of Standards
- 2D Frost Resistance Check
RAINWATER
Controlled discharge
When designing a building’s drainage system, you must consider not only the wastewater generated but also the discharge of stormwater into the public sewer system. The loads on the pipe network are primarily determined by the design rainfall intensity, which can be calculated in Dendrit CALHYDRA and Dendrit STUDIO using the property’s ZIP code and the catalog based on KOSTRA-2010R (Coordinated Regionalization and Evaluation of Heavy Precipitation by the DWD). Alternatively, the design rainfall intensities can also be entered manually in our solutions.
In Dendrit CALHYDRA and Dendrit STUDIO, roof drains for rainwater or emergency drainage are automatically designed based on the area to be drained, and the pipe network is sized in accordance with Section 14.2 of DIN 1986-100.
For roof drains, in addition to sizing in Dendrit CALHYDRA and Dendrit STUDIO, the backwater height is also determined based on the specified design rainfall intensity. If exceptional protection is required for buildings, you can also configure this in the calculation options. In this case, the full 100-year return period (ra (5,100)) is taken into account when sizing the emergency drainage system.
