Description
In this project there was a 7 l/s discharge restriction as a condition. On the basis of a flooding proof, a retention volume of at least 180 m³ was calculated. Due to limited height conditions, the retention body had to be designed very flat. The DRAINMAX tunnel system was chosen. As a partial infiltration of rainwater was not permitted, the complete system was welded into a 2 mm thick PE-HD foil.
