NIGP 96825: Corrosion Control Services

NIGP 96825 Corrosion Control Services, an Item code, covers chemical treatment and engineering services to mitigate corrosion and odor in water and wastewater infrastructure—work state and local governments are actively procuring for municipal water systems, drinking water plants, and sewer collection networks. Recent solicitations show municipalities and state agencies buying services ranging from injection of ferrous iron salt and ferrous chloride into wastewater pipelines to comprehensive corrosion control studies evaluating pH adjustment, calcium hardness modification, and corrosion inhibitor effectiveness through laboratory and field testing. Issuing bodies include city utilities departments (Dallas Water Utilities, Atascadero State Hospital public water system), state environmental or public health agencies (California Department of State Hospitals), and specialized facilities with corrosion-prone water infrastructure; activity spans municipalities of varied size and specialized state institutions.

Recent opportunities reflect geographic spread across Texas, California, and Georgia.

The California Department of State Hospitals solicited sealed bids under IFB 25-10042-000 in May 2026 for a Corrosion Control Study at Atascadero State Hospital mandated by the State Water Resources Control Board due to drinking water copper levels exceeding the regulatory limit; the contractor was required to evaluate corrosion control treatment options through pipe rig and metal coupon testing, with sealed bids due June 3, 2026, and performance required through February 1, 2027, under a five percent small business preference and incentive programs for Disabled Veteran Business Enterprises.
