UNSPSC 71131409: Chemical treatment monitoring services

Equipment for monitoring chemical treatments.

UNSPSC 71131409 Chemical treatment monitoring services is a Commodity code that state and local governments are using to tag water utility procurements focused on infrastructure inspection, cleaning, and rehabilitation work rather than chemical procurement or treatment monitoring in the traditional sense. Recent solicitations under this code span vacuum truck services, sewer-line and storm-drain cleaning, pipeline video inspection equipment, water main replacement, and water line installation—a mismatch between the code's nominal scope and what is actually being bought. The issuing bodies are municipalities and utility commissions, primarily in the Southeast and Southwest. The City of Phoenix requested vactor services (vacuum truck, jet rodding, hydro-blasting, and submersible pump work) across water treatment plants, wastewater treatment plants, and parks facilities under a five-year requirements contract (IFB-27-0462, due October 19, 2026), subject to DBE-N compliance and calling for a minimum of five years' business experience. The City of Alpharetta is soliciting on-call pipe lining services for storm drainage systems using CIPP or spincast methods, with proposals due May 28, 2026 via RFP 26-115. The Town of Waterford Utility Commission in Connecticut has posted two Invitation for Bids for plastic-to-copper water service replacement on FY26 and FY27 projects (IFB #26-007 due May 21, 2026, and IFB #26-014 due November 12, 2026), both subject to Connecticut prevailing wage requirements and 25% subcontractor set-asides for DAS-certified small and minority-owned businesses.

Recent activity concentrates in Florida, Georgia, Connecticut, Texas, and Arizona. Paulding County and Jones County in Georgia posted water main replacement and extension projects (bids due September 18, 2026 and July 7, 2026, respectively) calling for 16-inch, 12-inch, and 8-inch ductile iron or PVC water main installation with gate valves and appurtenances. The City of Fort Worth solicited installation of approximately 1,530 linear feet of 24-inch PVC water line on Comancheria Way (IFB due August 13, 2026), requiring prequalification for 24-inch water line work and MBE/SBE participation goals. The City of Meriden, Connecticut issued an Invitation for Bids on chemicals for water and wastewater treatment (ITB B026-55, due June 25, 2026)—calcium hypochlorite, caustic soda, aluminum sulfate, sodium permanganate, sodium fluoride, phosphate blend, and ferric chloride—with Build America Buy America Act sourcing restrictions on certain items and NSF and AWWA compliance required. The Texas Water Development Board requested proposals for mapping and line locates services for small rural water utilities (RFP due June 30, 2026, $4.75 million maximum, with VetHUB subcontracting plan requirements). No recent opportunities under this code show direct alignment with chemical treatment monitoring or laboratory services; the code's activity is driven by water infrastructure capital projects and utility operations support.
