The Metropolitan Water District of Southern California (MWDSC) maintains and
operates a number of diverse, pilot-scale water treatment platforms to support
the research efforts of the Water Quality Division. Until recently, each research
platform used a unique supervisory control and data acquisition (SCADA) system.
The original systems were either supplied by the research platform vendors or
custom-built by MWDSC staff. Because each system utilized a different user
interface, application development tool, or communication protocol, only a
limited number of personnel possessed the familiarity and ability to make rapid
changes in the systems. Many of the systems had been assembled and programmed
years earlier and could no longer be efficiently maintained because of
accelerated technological evolution and a lack of adequate documentation. This
paper describes MWDSC's efforts to upgrade and standardize the SCADA systems
associated with the research platforms. Issues concerning system planning,
design, implementation, ease of use, and cost are discussed. Includes tables.
