Backwater protection for waste water

inside the building

Backwater protection inside buildings with a gradient towards the sewer

Schematic diagram of a building with a backwater valve and a drainage pipe leading to the mains.

Solution 1:

with a backwater valve

A backwater valve protects the vulnerable area against backwater and, during normal operation, drains water via the natural gradient.

Solution 2:

with a backwater pumping station or a hybrid lifting station

A backflow pump or hybrid lifting station with a bypass protects the vulnerable area against backwater and drains the area during normal operation without the pump running.

Solution 3:

with a backwater lifting station

A backwater lifting station or hybrid lifting station protects the vulnerable area against backwater and performs drainage during normal operation without the need for pumping. In the event of backwater, drainage takes place via the backwater loop to the sewer.

RSE = backwater level, RSS = backwater loop

Solution 4:

using a lifting station

Wastewater disposal via a lifting station with a pressure pipe through the backwater loop, even in the event of backwater from the sewer.
