UNSPSC 47101579 Fresh/sea water treatment plant is a Commodity code that spans water and wastewater treatment infrastructure, operations, and rehabilitation work currently being solicited by municipal water authorities, county utilities, regional water districts, and state corrections and environmental management agencies. State and local buyers under this code are procuring comprehensive treatment plant services including plant operations and maintenance, chemical treatment and testing, facility rehabilitation and upgrades, lift station installation and replacement, mechanical integrity testing, sludge handling, and laboratory compliance testing. Recent solicitations show a diverse issuing-body mix: municipalities (Cities of Tampa, Phoenix, Palm Bay, Port Orange, DeBary, Macon, Tallahassee, Casselberry, Meriden, Fort Myers), counties (Collier, Orange, Pinellas, Wayne, Bergen, Clackamas, Fulton), water authorities (Great Lakes Water Authority, Macon Water Authority, Sacramento County Water Agency, Commonwealth of Kentucky), school districts (Hillsborough County Public Schools, Pinellas County School District), state agencies (Texas Department of Criminal Justice, Illinois Department of Corrections, Michigan Department of Natural Resources, Texas Division of Emergency Management), and regional transit/utility authorities (Port Authority of New York and New Jersey, Solid Waste Authority of Palm Beach County).

Geographic concentration is heavy in Florida (City of DeBary, Orange County, Collier County, Hillsborough County Public Schools, Pinellas County School District, Cities of Palm Bay, Port Orange, Tampa, Casselberry, Fort Myers), with significant recent activity in Michigan (Wayne County, Great Lakes Water Authority), Georgia (Fulton County, Macon Water Authority), Texas (TDCJ, TDEM), Ohio (City of Columbus Light and Water Department), and Oregon (Clackamas County). Representative current opportunities include Collier County's ITB for countywide chemicals for water and wastewater treatment across three treatment facilities with estimated annual spending of $4,000,000 and a four-year contract term due November 13, 2026; Clackamas County's sealed-bid solicitation for aeration basin refurbishment at the Tri-City Water Resource Recovery Facility with an engineer's estimate of $3.7 million and bids due November 10, 2026; the City of Phoenix's RFQ for 91st Avenue Wastewater Treatment Plant engineering services for process control pipeline rehabilitation due September 18, 2026; and Hillsborough County Public Schools' ITB for water and wastewater laboratory services due August 18, 2026 under the Small Business Encouragement Program. The code also captures significant capital projects such as Collier County's blend-tank construction at South County Regional Water Treatment Plant (estimated $4.27 million, due September 21, 2026), Orange County's $14.3 million SCADA and PLC upgrades at East Water Reclamation Facility (bid deadline August 31, 2026), and the City of Casselberry's water main replacement project (estimated $9.36 million). Operations and maintenance contracts dominate activity, with multiple Kentucky Commonwealth facilities, Texas Department of Criminal Justice, and Great Lakes Water Authority soliciting ongoing management of treatment systems. Set-aside and preference programs appear frequently—small business encouragement in Florida school districts, minority and women's business participation in Georgia and Oregon, VetHub subcontracting goals in Texas, and local-vendor preferences in Collier County and Palm Bay.
