Optimize pump engagement and minimize number of pump startups. Increase overall efficiency of wastewater pumping station.

In wastewater pumping stations (WWPS) it is of great importance to equally engage all pumps so clogging can be prevented. Also, it is very important to ensure automatic replacement of working pump in case of pump error.

Number of pumps in wastewater pumping station can vary depending on the size of the wet well. Wastewater pumping station controller by INDAS Automation is created to cover wastewater pumping stations with up to 16 pumps. Pumps can be organized into three groups to ensure priority during starting and stopping of the pumps. Beside priority, starting and stopping of the pumps is further determined by pump’s ID number or rest time.

It is very rare occurrence that two of wastewater pumping stations are exactly the same in terms of signals in the field. Wastewater pumping station controller has configurable PLC inputs and outputs with a wide range of predefined functionalities so it can be easily adapted to specific wastewater pumping stations.

Monitoring and parametrization of wastewater pumping stations is done over 7” touch panel. Parameters of wastewater pumping station controller can also be accessed over RS232/485 Modbus RTU communication. By adding GPRS modem, wastewater pumping station controller can be integrated in inVIEW Cloud SCADA system by our sister company INIT Technologies.

Wastewater pumping station controller by INDAS Automation was developed using Siemens S7-1200 series PLC and Weintek HMI. While the PLC and HMI application remains the same, number and type of signal modules in the PLC configuration is determined according to the number of signals in wastewater pumping stations.
