Sole Source: Teledyne ISCO Flow and Rainfall Monitor Parts, Equipment, Training and Associated Services and Licenses.

DeKalb County Department of Watershed Management is seeking a sole source procurement from Teledyne ISCO to provide parts, equipment, training, support, software, and licenses for its System-wide Flow and Rainfall Monitoring Program. This program, which operates under a Consent Decree with the EPA and Georgia Environmental Protection Division, utilizes approximately 300 flow monitors and 40 rain gauges to quantify sanitary sewer overflow volumes, identify high inflow and infiltration areas, and provide critical data for model calibration and construction. The contract is designed for a three-year term, with the sole source justification based on Teledyne ISCO being the only manufacturer capable of providing compatible parts for the existing 2400 Series and DuraTracker equipment. The scope of work specifically includes the provision of manufacturer-certified components such as area-velocity and ultrasonic sensors, battery node assemblies, tipping bucket rain gauges, and preventative maintenance kits. All equipment must be factory-tested and rated for submersible, corrosive, and high-moisture sanitary sewer environments. Notably, the contract excludes installation, calibration, field services, and data services. Payment will be made on an hourly or per-item basis for actual materials furnished, subject to county verification. Responses were due by September 30, 2026, via the OpenGov portal, requiring a capability statement and, for resellers, manufacturer authorization.
