A hard job, and extremely energy-intensive: here in the pumping station is where
the most power is supplied to the wastewater treatment plant. For Festo, this was
reason enough to develop its own solution. It was a roaring success:
power consumption in the entire plant in Sindelfingen/Germany was

The figures
In the pumping station, the wastewater from the primary sedimentation tank to
the biological treatment.
• Treatment capacity: equivalent to population of 250,000
• Operating specifications: 6 pumps, up to 5 pumps constantly in operation,
1 redundant. Pipe diameter: DN 350
• Pump specifications: rated output 90 kW, pump capacity 500 l/s with
8 – 9 m discharge head
• Energy savings: 89,469 kWh per year
• Cost savings: 11,594 Euro per year
The solution
Automated slide gate valves with quarter turn actuators DLP and directly
mounted Namur valves NFV3 replace the conventional non-return valve with
flap. The automated unit can be controlled via a centralised or decentralised PLC.
