NIGP 89004: Bar and Trash Screen Equipment and Parts

NIGP 89004 Bar and Trash Screen Equipment and Parts, an Item code, covers mechanical wastewater bar screens, trash traps, and related infrastructure that state and local governments install and maintain at water treatment and wastewater facilities, landfills, and stormwater systems. Typical procurements include the installation of mechanical bar screen systems with compactor conveyor assemblies, slide gates, and ancillary piping; rebuild and replacement of gravity thickeners and clarifiers; floating-barrier trash trap systems for creeks and waterways; and spare parts for existing equipment. Issuing bodies range across water authorities, county boards of commissioners, city public works departments, and county purchasing offices, with recent Georgia activity notably prominent—Macon Water Authority, Henry County, Paulding County, City of South Fulton, and City of Fairburn have all posted solicitations in the past four months.

Recent opportunities span IFB, RFP, and ITB notices with response dates between late June and late October 2026. The Macon Water Authority issued an IFB for rebuild of three 75-foot diameter gravity thickeners and clarifier #6 at Rocky Creek WRF (due October 20, 2026), requiring a Georgia Utility Contractor License and mandatory pre-bid attendance on October 6, 2026. Paulding County Board of Commissioners solicited sealed bids for installation of a mechanical wastewater bar screen with compactor conveyor system and related infrastructure at the county jail (due July 31, 2026). The City of South Fulton issued an ITB for installation and maintenance of floating-barrier trash trap systems at three creek sites plus maintenance-only at an existing site (due July 2, 2026), with an IDIQ structure offering up to four years of renewal options and a guaranteed minimum of $5,000 annually. Henry County posted an RFP for groundwater and methane gas monitoring services at two closed landfills (due September 10, 2026), which though focused on sampling and testing rather than equipment, reflects the broader environmental-compliance work tied to bar and trash screen regulations. Geographic activity concentrates in Georgia, with no recent opportunities identified outside that state in the source material.
