Delaware Engineering provided planning, design and construction supervision services to the Town of Fishkill for the Rombout Wastewater Treatment Plant upgrade. The new plant utilizes Sequencing Batch Reactor (SBR) technology and replaces an aging packaged aeration plant that was built in the early 1970s. The plant was designed to meet current SPDES permit limits and the effluent is discharged directly to the Hudson River. The 7,300 SF masonry building includes office space, sludge processing, electric, blower and controls rooms.
The plant process train consists of primary separation via grinding and mechanical screening, primary clarification, Sequencing Batch Reactor, Gravity Belt Thickener and chlorination. A full facility SCADA (supervisory control and data acquisition) system monitors and controls plant operations. The plant has been on line since October 2009 and effluent has consistently met all SPDES permit parameters.
