FIDCO, Inc., a subsidiary of Nestle Foods Corporation, operates a manufacturing plant and is host to a research laboratory in New Milford, Connecticut. The manufacturing plant produces a variety of food products and additives. The bulk of the manufacturing activities involve batch processes which generate a process wastewater stream highly variable in both flow and concentration. Operation of the research laboratory on an eight hour per day basis and the nature of the laboratory activities, contribute further to the variability of the combined (manufacturing plant plus research lab) wastewater stream. The waste stream is currently treated in an aerobic biological treatment system owned and operated by FIDCO.
