Hydraulic calculation for drainage systems

The functionality of a drainage system depends to a large extent on the hydraulic performance of the drainage channels installed. In order to make it easier for you we make your hydraulic calculation for your project. The software for checking the hydraulic performance of our drainage channels was developed from the university in Prague. We only need a few information such as size of area to be drainage, surface, rain intensity, channel type,... to make the calculation.

Please therefore just fill in the required data in the sheet below and send it to us.
