Area requirements for rainwater leakage in public roads — only separate seepage

The idealised area requirement for a leakage of rainwater generated in the public road country is shown proportionally to the drain-effective sealed area. The leakage is to be implemented separately due to the high traffic density for the areas of car traffic and cycling foot traffic. The declared pro rata area shall apply in each case to those modes of transport. In consultation with the Water Authority, the drainage of the area of the car traffic may be carried out as a sealed Mulden-Rigolen-System.
