UNSPSC 47100000: Water and wastewater treatment supply and disposal

UNSPSC 47100000 Water and wastewater treatment supply and disposal, a Family code, encompasses chemicals, equipment, and services that state and local governments procure to treat, test, and dispose of drinking water and wastewater. Recent solicitations show active procurement of chemical reagents (sodium hypochlorite, aluminum sulfate, polymers, chlorine, sodium bisulfite, liquid oxygen), specialized treatment equipment (PFAS remediation systems, filter backwash treatment facilities, lift stations), laboratory testing services, equipment repair and maintenance (pump stations, rotating biological contactors), construction of treatment infrastructure (piping, valves, sewer interceptors), and sludge and waste hauling and disposal. Issuing bodies span water utilities, municipal water departments, county water authorities, sewer districts, municipal authorities, county public schools, and special-purpose state park and environmental agencies. Repeat buyers include Pennsylvania municipal authorities (Capital Region Water, Lake Winola Municipal Authority, Lemoyne Municipal Authority, Waterford Municipal Authority, Plum Creek Municipal Authority, Chadds Ford Township Sewer Authority), Georgia water departments (Cartersville, Cobb County-Marietta Water Authority, City of Valdosta), Florida cities (Cocoa, DeLand, Tallahassee area), and state environmental service agencies in Maryland and Utah.

The geographic spread of recent activity includes heavy concentration in the Mid-Atlantic states—Pennsylvania, Maryland, Delaware—coupled with significant activity in the Southeast (Georgia, Florida), West (Utah, Oregon, Arizona), and isolated Midwest and Northeast opportunities. Representative recent procurements include Rockland County Sewer District #1 (New York) ITB for chemical degreaser (bids due November 12, 2026); Pike County Water & Sewerage Authority (Georgia) ITB for filter backwash water treatment facility construction (bids due November 13, 2026); Collier County (Florida) ITB for countywide water and wastewater chemicals covering 29 line items with estimated annual volume reaching $4,000,000 (bids due November 13, 2026); Charles County Board of Commissioners (Maryland) ITB for utility water piping and valve replacement at Mattawoman Wastewater Treatment Plant with 30% MWBE requirement (bids due July 8, 2026); Gainesville Regional Utilities Authority (Florida) ITN for acquisition and operation of Cross Creek Mobile Home Park water and wastewater systems (proposals due November 3, 2026); and Capital Region Water (Pennsylvania) ITB for 2027 sewer system improvements on unit-price basis (bids due October 27, 2026). Prevailing wage requirements, bond posting (5–10% bid bonds, 100% performance and payment bonds), site visits, and questions cycles are standard. Set-asides and preferences vary—MBE/DBE participation requirements appear in Maryland and federal-funded EPA projects; local-vendor preferences apply in Florida and Georgia; SBE goals are active in Texas school districts.
