UNSPSC 71131414: Scale inhibiting services

Inhibit scale formation

UNSPSC 71131414 Scale inhibiting services is a Commodity code that encompasses water infrastructure rehabilitation and maintenance work, including irrigation system upgrades, water service line replacements, pipeline cleaning and inspection, and water main installation and extension. State and local governments solicit under this code to maintain and upgrade potable and non-potable water distribution systems, stormwater infrastructure, and irrigation facilities. Recent activity involves cities, counties, and utility commissions issuing invitations for bids (IFB) and requests for proposals (RFP) for construction, rehabilitation, and on-call service contracts. Issuing bodies range from municipal water utilities and public works departments to county boards of commissioners and special-purpose water authorities. Representative work includes the Town of Waterford Utility Commission's sealed-bid procurements for plastic-to-copper water service line replacement (IFB #26-007 and IFB #26-014, Connecticut), the City of Alpharetta's RFP for trenchless pipe lining services covering storm drainage systems 12 to 120 inches in diameter (RFP 26-115, Georgia), the City of Phoenix's five-year requirements contract for vactor and hydro-blasting services across water and wastewater treatment plants (IFB-27-0462), and Paulding County's water main replacement project on Macland Road (sealed bid, Georgia, due September 18, 2026).

Geographic activity spans the Southeast and Southwest, with recent solicitations concentrated in Florida, Georgia, Connecticut, Arizona, and Texas. Paulding County and Jones County in Georgia, the Towns of Waterford and City of Lubbock are repeat buyers for water infrastructure work. The City of DeBary, Florida issued a competitive bid for Rob Sullivan Park irrigation system conversion (Bid 03-15, due April 10, 2015), the City of Fort Worth solicited prequalified bids for 24-inch PVC water line installation on Comancheria Way (City Project 106854, due August 13, 2026), and the Texas Water Development Board requested RFP proposals for mapping and line-locate services serving rural water utilities under 1,100 customers (RFP 58026RFP0015, due June 30, 2026, maximum $4.75 million). Many contracts carry prevailing wage requirements, bonding and insurance mandates, and minority or small-business subcontracting set-asides, particularly in Connecticut (25 percent DAS-certified SBE/MBE set-aside) and Phoenix (DBE-N compliance). Work-assignment structures range from competitive single-award IFBs to multi-award on-call contracts with task order issuance, with completion timelines typically spanning 30 to 120 calendar days.
