UNSPSC 70170000: Water resources development and oversight

UNSPSC 70170000 Water resources development and oversight is a Family code under which state and local governments procure engineering, design, construction, and professional services for water infrastructure projects including treatment plants, distribution systems, stormwater management, wastewater facilities, and related environmental compliance work. Recent solicitations show the code captures wetland and stream assessments, water mainline replacements, pump station rehabilitation, treatment plant modifications, and stormwater diversion systems—work that spans civil engineering, construction management, specialized consulting, and capital improvement delivery across multiple project phases and funding sources.

Activity under this code is geographically dispersed across California, Florida, Washington, Colorado, Pennsylvania, Texas, Arizona, and Utah, with notable recent opportunities from Sacramento County, the City of Thousand Oaks, Lewis County (Washington), Hillsborough County (Florida), Broward County (Florida), the City of North Miami Beach, Heber Valley Special Service District (Utah), and several smaller municipal and county water authorities. Lewis County appears as a repeat buyer, issuing multiple concurrent solicitations for wetland and stream services, structural engineering, and roadway safety projects. Representative recent opportunities include Lewis County's RFQ for wetland and stream services supporting federal safety projects (CRP2212A/B, proposals due October 14, 2026, approximately $48,000 combined value), Sacramento County's competitive bid for a 350,000-gallon potable water prestressed concrete tank at Rio Consumnes Correctional Center (Contract 4689, sealed bids due October 15, 2026, estimated $4.9 million), and the City of Thousand Oaks' sealed-bid solicitation for water mainline replacements at five city locations (CI 5493, bids due July 1, 2026, engineer's estimate $650,000). A significant portion of recent work carries federal funding (FHWA, FTA, EPA, BOR) and triggers prevailing wage, Davis-Bacon, DBE, Section 3, and Title VI compliance obligations. Design-phase work under this code frequently uses RFP or RFQ procurement structures with hourly rate or fixed-fee compensation, while construction typically follows sealed competitive bidding with engineer's estimates ranging from under $100,000 for equipment repairs and tank maintenance to $29 million for landfill liner systems and over $10 million for stormwater and signal upgrades. Water infrastructure opportunities remain active but show concentrated regional demand in California's interior and coastal counties and South Florida metropolitan areas.
