Enterprise Supervisory Control and Data Acquisition Project

Challenge 

There was a need for a standardized SCADA architecture in Caltrans that could remotely access, monitor, gather, and process data from geographically disparate facilities such as rest areas, truck inspection facilities, and maintenance stations. Caltrans IT aimed to provide a solution that would apply to numerous industrial applications for water and wastewater treatment systems, storm water pumping plants, and tunnel monitoring systems at statewide transportation-related facilities.

Solution

The SCADA system can identify equipment performance, send notifications of potential equipment failure, and automate the daily check-in process for statewide maintenance staff by collecting water and wastewater data for mandated monthly local Water Board reports. This process eliminated the need for Caltrans staff to conduct regular field surveys and limited the closure of facilities to the traveling public. 

Result  

The new application: 

• Includes enterprise SCADA architecture

• Centralizes statewide data sharing for historical trends  

• Reduces waste and improves efficiency at statewide facilities

• Provides flexibility for each district to architect their own SCADA system for each industrial application

• Allows for implementation of preventive measures for unforeseen weather conditions and equipment failures 

• Automates inspection and monitoring process for increased public safety
