Project: Baton Rouge Wastewater Pump Station SCADA System July 25, 2005

July 25, 2005

The city’s non-renewal of the overall engineering consultant’s contract is looming as an obstacle to the engineering schedule. The city engineer’s prior time commitments are leaving little time available for him to serve in this capacity. This is resulting in our requests for information going unanswered.

The engineering team completed a site visit to the city’s existing SCADA system. The physical layout of the hardware and communication networks was examined as well as the current distribution of software functions among computers, which varied considerably from what was indicated in the request for proposal documents.

Although the current system employs one of the most popular graphical interface packages used in this industry, Indusoft 6.0 Web Studio was recommended for this application. It has the ability to duplicate the existing system’s functionality while publishing real-time dynamic and animated graphic screens, trends, alarms and reports to standard Web
browsers natively (without additional configuration). It can also be configured for complete data logging and Web interface redundancy, proven in earlier large scale applications.

A major design goal is to move away from the present system of central control room-centric data gathering toward a system where it is possible to grant full or partial SCADA access to any employee via their desktop PC, a cellular-enabled mobile workstation or a Web-enabled cell phone. This includes text critical alarm transmissions directly to cell phones and
pagers as well as automatic distribution of reports via email in Microsoft Excel format.
