About this file
This is a bulk and mini-bulk chemical requirements document for the Onslow Water & Sewer Authority (ONWASA) in North Carolina, detailing treatment facility chemical specifications across multiple water treatment plants and wastewater treatment facilities. ONWASA requires delivery of various chemicals including Aluminum Sulfate (Commercial Alum), Liquid Sodium Hypochlorite 12.5%, Sodium Permanganate 20%, Peracetic Acid, Citric Acid Salt, Non-Methanol Carbon, Liquified Hydro Fluorosilicic Acid, Zinc Ortho-Phosphate, and mini-bulk chemicals such as Granular Calcium Hypochlorite, Tablet/Stix Calcium Hypochlorite, Liquid Lime, and Hydrated Lime. The chemicals are distributed across eight primary facilities: Hubert WTP, Dixon WTP, Northwest Regional WWTP, Southeast Regional WWTP, Summerhouse WWTP, Webb Creek WWTP, and multiple Black Creek Wells. Estimated FY 25/26 total usage ranges from zero gallons at facilities under construction to over 100,000 gallons for certain chemicals at established facilities, with delivery frequencies varying from weekly to yearly depending on chemical type and facility requirements.
The solicitation is being conducted as a multistep competitive sealed bid consisting of Phase 1 unpriced technical proposals due prior to 2:00 pm on Monday, August 31, 2026, followed by Phase 2 price proposals and a reverse auction. ONWASA has partnered with EasiBuy, LLC to host the reverse auction event on its web-based bidding platform. Storage capacities at facilities vary significantly, from 40 gallons at individual wells to 120 tons at water treatment plants, with delivery frequencies typically ranging from two weeks to monthly for liquid chemicals and longer intervals for bulk solids. The document does not specify contract term, renewal options, pricing structure, or set-aside provisions, as this requirements document serves as the technical foundation for the forthcoming competitive solicitation process.
