SCADA and GIS/GPS

SCADA

COMB utilizes a Supervisory Control and Data Acquisition (SCADA) system to monitor remote facilities from a central location. SCADA is a control system architecture that uses computers, networked data communications and graphical user interfaces for high-level process supervisory management.  SCADA uses other peripheral devices such as programmable logic controller (PLC) and discrete PID controllers to interface with the system. 

GIS/GPS

Although the South Coast Conduit (SCC) typically needs minimal maintenance, it remains COMB's primary asset and responsibility. The 26 mile conduit lies underground which makes it imperative to have the capability of accurately locating the pipeline without excavation. For this reason, COMB transitioned from reliance on original profile and alignment drawings to a more advanced and up to date method of locating the pipeline. The original drawings display topography traits which are vastly different from current contours due to changes in structures, roads and the natural environment. In many cases, homes, communities and modern roads exist today that were not represented in earlier records. Visual cues are less reliable today and require additional research to accurately locate a given point. COMB utilizes a GPS location system to help modernize the process. 

COMB participates in the Dig Alert system. With modern utilities installing transmission lines underground, it is necessary to assist homeowners and contractors to safely discover existing utility components beneath potential work sites.  The Dig Alert system notifies any utility of a possible conflict with other utilities. It is potential for COMB to receive up to 20 dig alerts per day. Along with increased efficiency, the Dig Alert system provides a cross communication of information given to outside agencies and contractors. To aid in that effort, a navigable map using a color coded pipeline and existing roads/topography is the most logical medium of communication.
