Supervisory Control and Data Acquisition
SCADA is the system that controls the various operating processes at our facilities. It is also the system that collects and stores real-time data from sensors and other devices for reporting, analysis and
processes.
Superv rvisory Control and Data Acquisition
You encounter SCADA-like systems almost every day. Most of today’s vehicles are equipped with systems similar to SCADA.
Rivanna’s SCADA system is utilized by its operators and managers to monitor and supervise the production and treatment processes at the water and wastewater facilities.

trending parameters are continuously monitored and adjusted as needed using real- time raw data. This allows the SCADA “system” to make adjustments as conditions change.

The PLC, much like a computer, serves as the central processing unit. It houses most of the major programming and communicates with devices and servers via the network. The bulk of PLCs used by Rivanna are manufactured by GE and controlled by GE proprietary software. The PLCs require periodic software updates.

Human Machine Interface
HMI is a program that runs on a standard desktop or laptop workstation. The operator interacts with the SCADA system using the Dashboard/HMI screen. With the use of PLCs, the network and connected devices, the operator has the ability to:

SCADA technology is essential to meet modern day needs of the municipal water and wastewater industry. Complicated treatment processes – Nutrient reduction goals for the ENR project would be difficult to achieve without the precision of SCADA. Vital data that was once thought to be unattainable is now available instantly. Real time data (Efficient resolution of line break and distribution issue.) Efficiencies: Sampling changes, staffing efficiencies, remote monitoring
Ensuring that our SCADA system is secure at all times is a number one priority.

Data is the heart of SCADA. All of the information collected is stored in databases and can be accessed at any time.
Data is used for:
