Application is based on a drivers of Telemechanique TSX Premium series and WizFactory package.

The system is aimed at improvement of work in the treatment plant, makes the acquisition of processing and archiving of data on work and the status of individual devices.
The system is equipped with an alarm mode notifying service on exceeding the minimum and maximum values of the measurements, failures of motors and pumps and other equipment.

The main task of the system is visualization of pumps, motors, fans, analog measurement values (pressure, level, temperature, density of wastewater) along with their transgressions and control actuators, valves and mixing units.
Data archiving module is responsible for the archiving of measurements of daily and monthly hours of work of equipment and the amount of energy produced.
Biogas-fueled power generators produce 60% of the electricity needed for operation of the facility. The investment was completed with the use of EU funds under the Phare Programme.
