UNSPSC 12164101: In situ additives

UNSPSC 12164101 In situ additives is a Commodity code for chemical products and services that state and local water and wastewater treatment facilities use to clean, treat, and control systems in real-time — products injected or applied directly into pipelines, tanks, and treatment infrastructure to address corrosion, scaling, odor, microbial activity, and hydrogen sulfide. Recent solicitations across water departments, wastewater authorities, and utility districts show active procurement of pipeline-cleaning chemistries (proprietary blends for tuberculation and biofilm removal), treatment polymers for solids dewatering, odor and corrosion control additives (ferrous iron salts, ferrous chloride, magnesium hydroxide slurry), and specialized chemicals for leachate and landfill gas condensate systems. Issuing bodies span city and county water departments, regional water authorities, and municipal utilities in Florida, Georgia, Michigan, California, Texas, and Missouri; Sarasota County, the City of Tallahassee, Gwinnett County, the Tampa Convention Center, and the City of Dallas have posted recent solicitations under this code. Most opportunities are structured as annual or multi-year supply contracts with firm or fixed pricing, typically awarded on lowest responsive and responsible bidder basis, with mandatory NSF 60 or NSF 61 certification requirements and AWWA standard compliance standard across all chemical products.

Recent activity concentrates in the Southeast, particularly Florida and Georgia, with secondary clusters in Michigan and California. Representative recent solicitations include Sarasota County's sole-source procurement (ISS 2026-ISS-767, due July 15, 2026) for Pipe & Well Renew proprietary chemical products and cleaning services for leachate and landfill gas condensate systems; the City of Tallahassee's magnesium hydroxide slurry contract (IFB-067-26-CPW, due June 16, 2026) for hydrogen sulfide and odor control across 1,000 miles of sewer main and 114+ pump stations; the Dallas Water Utilities odor and corrosion control services contract (BR2600030262, due June 26, 2026) for liquid ferrous iron salt, ferrous chloride, and bioxide injection on a 36-month ID/IQ basis with an estimated $10 million value; and Gwinnett County's solids dewatering and thickening polymer contract (BL076-26, due July 30, 2026) for belt filter press and centrifugation applications across three regional water facilities. Most contracts require vendor performance testing, include quarterly or annual price adjustment caps (typically 3–5 percent), and mandate business continuity insurance including pollution liability and workers' compensation at $1–2 million coverage levels. Set-asides vary by jurisdiction; Dallas applies SBE participation goals under its DRIVE Policy, and GLWA applies mandatory Business Inclusion and Diversity scoring, but most Florida and Georgia solicitations carry no explicit set-asides beyond local-vendor preference provisions.
