Liquid Ammonium Sulfate

The North Texas Municipal Water District (NTMWD) is soliciting sealed bids for an annual contract to purchase Liquid Ammonium Sulfate for water treatment disinfection processes. The procurement seeks approximately 9,000 total tons of liquid ammonium sulfate to be distributed across five delivery locations: Bonham WTP (30 tons), Leonard WTP (725 tons), Tawakoni WTP (245 tons), and Wylie Complex (8,000 tons). The product must meet stringent specifications, including ANSI/NSF Standard 60 certification, AWWA Standard B302-05 requirements, and contain 9.8 to 10.3 percent NH3. Bidders are required to submit comprehensive documentation including Safety Data Sheets, laboratory analysis, disaster recovery plans, and three client references. A mandatory pre-bid meeting is scheduled for Tuesday, September 2, 2025, at 10:00 AM Central via Webex, with bid questions due by 4:00 PM Central on Wednesday, September 3, 2025. Bid submittals are due by Friday, September 12, 2025, at 10:00 AM Central, with submissions accepted electronically through ntmwd.bonfirehub.com or physically delivered to NTMWD's procurement department in Wylie, Texas.

The contract will be awarded to the lowest responsive, responsible bidder meeting all specifications, with NTMWD reserving the right for multiple awards and secondary vendor arrangements. The initial contract term is one year, with potential for four additional one-year renewal options, extending the total contract period to five years. Pricing will be structured as unit pricing per wet ton delivered FOB destination to specified NTMWD treatment facilities, with prices firm for the initial contract period and subject to annual adjustments based on the Argus North American Fertilizer Index during renewal periods. Deliveries must be made within one working day of order receipt via bulk tanker truck with self-pressurized pneumatic systems, and must include certified scale weight tickets. While no specific set-aside designations are mentioned, bidders will be evaluated on their ability to meet technical specifications, provide comprehensive documentation, and demonstrate reliability in product delivery and quality. The procurement does not explicitly state a total contract value, but the annual quantity of 9,000 tons suggests a significant procurement volume for the water treatment facilities.
