UNSPSC 30111604: Hydrated lime

UNSPSC 30111604 Hydrated lime is a Commodity code covering bulk hydrated lime supply for water, wastewater, and infrastructure projects. State and local governments procure hydrated lime primarily for water resource recovery facilities, sewer infrastructure work, and construction applications where pH adjustment, stabilization, or soil treatment is required. Recent solicitations show hydrated lime appearing as a supply component within larger infrastructure rehabilitation and construction projects rather than as a standalone procurement.

Issuing bodies soliciting under this code include water resource recovery districts, county sanitation agencies, and municipalities engaged in infrastructure construction. Clean Water Services, a water resource recovery district in Oregon, issued an ITB on September 17, 2026 for bulk hydrated lime delivery to three facilities (Rock Creek, Durham, and Forest Grove Water Resource Recovery Facilities) under a twelve-month contract commencing November 1, 2026, with bids due September 30, 2026 via Equity Hub's Bid Locker portal. The City of Cedar Park, Texas identified white hydrated lime as a commodity available through its vendor availability lists for the Northern Walnut Creek Trail construction project, an IFB issued August 24, 2026 with response due September 17, 2026. Santa Clara County and Bleckley County, Georgia also posted infrastructure projects in August–September 2026 that may incorporate hydrated lime as a material component, though neither explicitly named lime in their primary scope summaries. Recent activity concentrates in Oregon, California, Texas, and Georgia, with water utilities and transportation/infrastructure agencies as primary buyers.
