NIGP 69029: Controls, Electro Hydraulic (Ehc)

NIGP 69029 Controls, Electro Hydraulic (EHC), an Item code, encompasses electro-hydraulic control systems and components that state and local governments procure for infrastructure equipment rebuild and maintenance—particularly gravity thickeners, clarifiers, and related water treatment mechanisms. The code captures replacement control hardware, actuation systems, and integrated controls for mechanized equipment in municipal water reclamation and treatment facilities. Issuing bodies soliciting under this code include municipal water authorities and county departments managing utility infrastructure and municipal facilities. The Macon Water Authority and DeKalb County—both Georgia jurisdictions—have posted recent opportunities involving electro-hydraulic component replacement as part of larger capital rehabilitation projects.

Recent activity centers on Georgia, where two major solicitations posted between June and September 2026 involve electro-hydraulic controls as components of broader infrastructure upgrades. The Macon Water Authority issued an IFB (Solicitation PE33561NONST2027000000073) for the rebuild of gravity thickeners 1, 2, and 3 and clarifier #6 at Rocky Creek Water Reclamation Facility, with bids due October 20, 2026, requiring replacement of thickener mechanisms and associated components on a lump-sum, general-contractor-performed basis. DeKalb County issued an ITB (PE64400NONST2026000000260) for reconstruction of the DeKalb Tennis Center with IT and low-voltage infrastructure components due July 13, 2026. Both solicitations required mandatory pre-bid meetings and established bonding and licensing thresholds typical of municipal construction and infrastructure work.
