An apparatus for controlling a flow of a liquid into a sewer drain comprising a catch basin having a catch basin drain coupled with the sewer drain. In addition, a housing element that is positioned within the catch basin, whereby the housing element is coupled with the catch basin drain in a first fluid-tight manner. The housing element having a porous surface positioned below a predetermined level. A column having a proximal end and a distal end, whereby the column is positioned within the housing element and the proximal end is coupled with the catch basin drain in a second fluid tight manner. The distal end is positioned above the predetermined level and an actuator mechanism is coupled with the column and configured to selectively open and close the column to the flow of the liquid that is entering the catch basin drain.

An apparatus for controlling a flow of a liquid into a sewer drain comprising a catch basin having a catch basin drain coupled with the sewer drain. In addition, a housing element that is positioned within the catch basin, whereby the housing element is coupled with the catch basin drain in a first fluid-tight manner. The housing element having a porous surface positioned below a predetermined level.

The collision safety device as claimed in claim 5, characterized in that the lower edge of the rear wall (36) is located on a lower level than the rear end (39) of the lower wall (35). 7. The collision safety device as claimed in claim 4, characterized in that the configurationally stable walls include a rear wall (36) which is located at the exit end of the forming device (7) and has a lower end (37) on a lower level than the crash barrier girder (3, 4; 28), the crash barrier girder which, in its longitudinal direction, is positionally fixed by the drawing member (23, 24), being disposed to be bent to a position with its longitudinal direction approximately along the ground. 8. The collision safety device as claimed in claim 1, characterized in that the forming device (7) has two entry ends (17, 18) placed for cooperation with two mutually superposed crash barrier girders (3, 4; 28) and two exit ends (19, 20) located side-by-side at ground level (1). 9. The collision safety device as claimed in claim 1, characterized in that the forming device (7) has an entry end of tall, narrow configuration for accommodating a crash barrier girder (3, 4; 28) of tall, narrow cross section, the crash barrier girder having, between an upper (40) and a lower (42) portion, a longitudinal fracture indication (43); and that in the region of the entry end, there is disposed a splitter device (44) which, when it, together with the forming device (7) is displaced along the crash barrier girder, is disposed to separate the upper and lower portions of the crash barrier girder from each other. 10. A collision safety device at an end section of a crash barrier (2), and comprising at least one crash barrier girder (3, 4; 28) or profile extending approximately parallel to and above the ground at a first level, a safety member (6) in the area of the end portion of the crash barrier, the safety member being disposed to be hit by a colliding vehicle, and, under the action thereof, to be displaced along the crash barrier (2), the safety member having a forming device (7) engaging with the crash barrier girder (3, 4; 28) for realising an energy-absorbing configurational change in the crash barrier girder (3, 4; 28) on the displacement of the safety member along the crash barrier, characterized in that the forming device (7) has an entry end (8) at said first level of the undeformed crash barrier girder (3, 4; 28) and an exit end on a second level than said first level in order that the deformed crash barrier girder can be driven over by the colliding vehicle, characterized in that the forming device (7) includes a number of configurationally stable walls or surfaces which, on displacement of the safety member (6) along the crash barrier, are disposed to deform the crash barrier girder (3, 4; 28), further characterized in that the forming device (7) has, at its entry end (8) a tube (11, 12) for accommodating the crash barrier girder (3, 4; 28), a first curved section (13, 14) for oblique downward curving of the crash barrier girder, and a second curved section (15, 16) for bending the crash barrier girder along the ground (1). 11. A method of preventing or reducing damage to a vehicle and injury to its passengers if the vehicle collides with an end section of a crash barrier (2), comprising the steps that a crash barrier girder or profile (3, 4; 28) included in the crash barrier is provided with a forming device (7) which, under the action of a colliding vehicle, is displaced along the
