Metropolitan St. Louis Sewer District Selects Foxboro Control System for State-of-the-Art Wastewater

Foxboro Automation Systems, a unit of Invensys Process Systems, has been awarded a $1.1 million contract by the Metropolitan St. Louis Sewer District (MSD). Under this contract, Foxboro will provide an advanced I/A Series automation system for the new, state-of-the-art Lower Meramec River Wastewater Treatment Plant under construction on a 200-acre facility located near the confluence of the Mississippi and Meramec Rivers. Designed to initially treat 15 million gal. per day of influent, the District has designed the new plant so that it could be expanded to ultimately handle up to 56 million gal. per day.

The new Lower Meramec River plant will incorporate the latest I/A Series automation technology to enhance operations, reduce costs, and help ensure governmental compliance. This includes state-of-the-art Switched Ethernet networking in highly reliable "mesh" network configurations, new field-mounted I/A Series control processors, and remote input/output (I/O) devices with digital communications to the field instrumentation.

Plans are also in place to ultimately network the I/A Series control system being installed in the new plant with the Foxboro systems already installed in existing District treatment plants. The objective is to create a District-wide control network that will help to further improve operations and reduce costs, while meeting all governmental regulations for discharge standards.
