摘要

The waste water collection system uses a leak-free water collection shaft (1), sunk into the ground, provided with an opening (19) in its vertical wall, for passage of a horizontal line (31) connecting a vertical line section (32) extending towards the bottom of the collection shaft with a vertical line section (33) on the outside of the collection shaft, leading to a connection fitting (5) for a water collection vehicle suction line, positioned above the ground.
