NIGP 33509: Ammonium Phosphate

NIGP 33509 Ammonium Phosphate, an Item code, describes chemical inputs state and local governments procure for water treatment, wastewater nutrient management, and turf or grounds maintenance. Recent solicitations show that purchasing under this code splits between specialized process chemicals for municipal wastewater systems and bulk fertilizer supplies for maintenance operations. The City of Orem is soliciting a complete phosphorus control system for its water reclamation facility that will use chemical feed and storage systems—likely including ammonium phosphate or phosphate-based compounds—to treat anaerobically digested sludge through controlled struvite precipitation; Pasco County, Florida, is seeking herbicides, fertilizers, and pesticides on an as-needed basis for delivery to two county maintenance facilities. Issuing bodies purchasing under this code include municipalities (city water utilities) and county government departments managing wastewater treatment and grounds maintenance.

The code shows activity across the Southwest and Southeast. The City of Orem, Utah, posted RFP PROJECTNO230904 for the phosphorus control system with proposals due October 16, 2026; Pasco County, Florida, issued IFB IFBSP26074 for herbicides, fertilizers, and pesticides with bids due June 16, 2026, with a contract term running through September 30, 2029 and potential extension. The Orem solicitation is federally funded through an EPA grant and emphasizes integrated system design and performance, with the selected supplier responsible for equipment design, fabrication, factory testing, delivery, installation support, operator training, and one-year warranty. The Pasco County procurement is structured as an as-needed supply contract with deliveries required Monday through Friday between 6:00 a.m. and 2:00 p.m., with all granular products packaged in bags no larger than 50 pounds.
