The backwater pumping station for non-faecal wastewater is equipped with two submersible pumps and a motor-driven as well as a mechanical closure system. The collection tank made of permanently resistant polymer (PE) has an enclosed pump tank. Quick-release closures enable the integrated components to be removed easily. Normally, draining takes place via the natural fall to the sewer. Backwater is detected by an optical probe, which causes the motor-driven closure system to close automatically and there is no longer free passage to the sewer. During the backwater phase, the water drains directly into the sewer via the pumps. The station is controlled by a user-friendly control unit, which can be optionally integrated in the building control system via a potential-free contact or optional alarm and collective fault messages can be output via a GSM interface. The KESSEL modular system provides different upper sections and engineering chamber options as accessories.
