NIGP 69033: Controls, Single Loop

NIGP 69033 Controls, Single Loop (Item) covers the supply and installation of single-loop control systems and associated instrumentation that state and local governments procure for water treatment, wastewater facilities, and building infrastructure. Recent solicitations show purchasing concentrated in wastewater and water authority capital projects where single-loop controls regulate thickener mechanisms, clarifiers, gates, and related process equipment as part of facility reconstruction or upgrade scopes. Water and wastewater authorities dominate the issuing-body mix, with county governments appearing in supporting roles for infrastructure coordination and IT systems integration related to control-system deployment.

Georgia has driven recent activity under the code, with the Macon Water Authority posting an IFB for Rebuild Gravity Thickeners 1, 2 and 3 and Clarifier #6 at Rocky Creek WRF (due October 20, 2026), requiring replacement of thickener mechanisms and clarifier components on a lump-sum basis with mandatory pre-bid attendance on October 6, 2026, and a Georgia Utility Contractor License as a prerequisite; and DeKalb County posting an ITB for reconstruction of the DeKalb Tennis Center (due July 13, 2026) that includes furnishing and installing IT and Low Voltage Infrastructure systems with associated cabling, raceways, and terminations in accordance with county standards. Both opportunities reflect capital-renewal cycles at public facilities where control systems and instrumentation are embedded in larger construction or infrastructure modernization contracts rather than procured as standalone equipment.
