NIGP 17578: Screening and Sieving Apparatus and Accessories: Riffle Samplers, Sieve Shakers, etc.

NIGP 17578 Screening And Sieving Apparatus And Accessories: Riffle Samplers, Sieve Shakers, Etc., an Item code, encompasses mechanical screening and sieving equipment and services that state and local governments procure for environmental sampling, waste processing, and laboratory operations. The code captures both the supply of screening apparatus — including pumps and instruments for groundwater quality monitoring — and the provision of screening services for municipal waste streams. Issuing bodies span city public works departments, regional water management districts, state environmental and natural resource agencies, county fire-rescue operations, and departments of agriculture. These jurisdictions treat screening both as a capital equipment acquisition and as an outsourced operational service bundled with equipment ownership, maintenance, and disposal management.

Recent activity spans Kansas, Florida, Georgia, and Missouri. The City of Wichita Public Works & Utilities Department posted IFB 260203 (due August 14, 2026) seeking mechanical screening of street sweepings and finished compost at Brooks Landfill — approximately 16,000 cubic yards annually through 1.5-inch and half-inch screens, with vendor-owned equipment, all on a cost-per-cubic-yard and cost-per-ton pricing model and one-year contract with four optional one-year renewals. The St. Johns River Water Management District posted ITB 16494 (due July 31, 2026) for Grundfos submersible groundwater pumps (GeoFlo 3 and Redi-Flo2 models) in environmental sampling across its 18-county service area in Florida, with an estimated budget of $199,990 and approximately 48 pump units required on an as-needed basis. Additional recent solicitations in the broader equipment and services space include Fulton County, Georgia's IFB for fire and rescue equipment and SCBA maintenance (due July 28, 2026) and Missouri's RFP for laboratory relocation services encompassing analytical instruments and hazardous-chemical transport (due August 11, 2026).
