About this file
These are engineering drawings for the Town of Oxford Water System Improvement SCADA Rehabilitation project located in Talbot County, Maryland. The project encompasses the installation of new sensors in existing water storage tanks at two locations (Tilghman Street and JL Thompson Drive), the integration of new SCADA software, and the connection of signals into the Town's existing SCADA system. The drawings detail electrical system modifications including the removal and replacement of existing load centers with new Square D QO load centers, installation of new tank level pressure transducers with 3-conductor shielded cabling, new SCADA antennas mounted to tank antenna corrals, and the coordination of signal transmission to existing remote terminal units (RTUs). The project involves upgrades to the control room electrical infrastructure at both the water tank site and the wastewater treatment plant facility, with work including conduit installation, wiring modifications, and equipment replacement to accept new input signals from the upgraded sensors.
The technical specifications indicate that all workstation equipment shall be replaced with current manufacturer model equipment, with detailed coordination required with equipment manufacturers and suppliers for signal re-transmission capabilities. The drawings reference specification section 16900 for scope details and Division 13, sections 13900, 13950, and 13990 for specific implementation details. Construction details are included for erosion and sediment control measures, including stabilized construction entrance, silt fence, and super silt fence installations. The project documentation was prepared by an engineering firm with offices in Baltimore and Easton, Maryland, with drawing dates of April 10, 2026, and revision dates of June 23, 2026.
