NIGP 18002: Abrasives: Feldspar, Pumice, Silica, etc.

NIGP 18002 Abrasives: Feldspar, Pumice, Silica, Etc. is an Item code under which state and local governments procure filter media and related materials for water and wastewater treatment operations on an as-needed basis. The recent solicitation activity under this code reflects municipal demand for specialized filter materials that meet regulatory compliance standards and quality control documentation requirements, typically sourced under single-lot, single-source supply agreements. Issuing bodies include mid-size and large cities with established water and wastewater infrastructure; repeat buyers and geographic concentration are not evident from the current opportunity set.

The City of Fort Worth posted RFP 26-0173 on April 13, 2026, seeking filter media proposals due May 7, 2026, with a requirement for three years of prior municipal water and wastewater treatment supply experience, firm pricing on FOB Destination Freight Prepaid and Allowed terms, a one-year initial contract renewable for up to four additional one-year periods, and a 30 percent small business utilization goal for Tarrant, Wise, Johnson, Parker, or Denton County–certified firms. The City of Lubbock concurrently solicited hazardous waste collection and disposal services through ITB 26-19408-SR due March 26, 2026, representing a related but distinct procurement stream focused on waste management rather than filter supply. Geographic activity is concentrated in Texas, with Fort Worth and Lubbock representing the two largest recent opportunities; broader state or regional pattern data is not supported by the current opportunity set.
