Wastewater lifting station

A wastewater lifting station, comprising:

• at least one bulky-material collection container;
• and
• at least one separating screen arranged in an interior of the at least one bulky-material collection container, the at least one separating screen being configured to guide wastewater therethrough while separating bulky materials from the wastewater,
• wherein the at least one separating screen
• subdivides the at least one bulky-material collection container into a bulky-material loaded region and a bulky-material free region,
• is pivotable via a hinge to a flange of the bulky-material collection container,
• at least in a peripheral region remote from the hinge—has at least one cut-out which is open toward an outside edge adjacent to a side wall of the at least one bulky-material collection container,
• the at least one separating screen bears obliquely on a sealing region of the bulky-material collection container, and
• the at least one separating screen is arranged in the bulky material collection container such that in a reverse flow cleaning operation, the at least one separating screen is raised by the reverse flow from the sealing region to form a flow passage through a gap between the raised at least one separating screen and the sealing region of the bulky-material collection container.
