UNSPSC 47101503: Carbon filtration equipment

UNSPSC 47101503 Carbon filtration equipment (Commodity) covers water treatment filtration systems and components—sand filters, cartridge housings, blend tanks, chemical injection piping, membrane modules, and replacement media—that state and local water systems procure to treat potable water, reclaimed water, and wastewater to regulatory standards. Recent state and local solicitations show municipalities and special districts buying equipment across three main workflows: replacement of worn or obsolete systems in operating treatment plants (lime softening improvements, drive shaft assemblies for softening equipment, pool and recreational water filters); retrofit and refurbishment of existing filter galleries and pressure piping; and procurement of replacement consumables (filter media, cartridges, microfiltration membranes) as part of ongoing maintenance contracts. Issuing bodies include water treatment utilities (Collier County, Riverside County RFQ activity), municipal water departments (City of Holly Hill, City of Plant City, West Basin Municipal Water District), and school districts (Yale Public School District, Dallas Independent School District). The code also captures water treatment services contracts where equipment supply and installation are bundled with labor, as seen in the Florida-based sole-source procurements and the California Department of Water Resources' multi-facility service solicitations.

Geographic activity concentrates in Florida (Holly Hill, Plant City, St. Petersburg, Collier County, Hillsborough County), California (Riverside County, West Basin, DWR multi-division contracts), and Texas (Dallas ISD, Bell County, Southlake). Recent representative opportunities include Collier County's $4.27 million sealed bid for lime softening improvements and a blend tank at its South County Regional Water Treatment Plant (IFB Bid No. 26-8683R, response deadline September 21, 2026); the California Department of Water Resources' invitation for bid on comprehensive water treatment system services across four field divisions (IFB #10220465, due August 18, 2026); Bell County, Texas's bid for conventional water treatment plant filter gallery modifications with an engineer's estimate of $2.25 million (due August 25, 2026); and Dallas Independent School District's RFP for district-wide water treatment services with a three-year base term and two one-year renewal options, carrying a mandatory Small Business Enterprise participation goal of 30 percent and evaluation weight up to 20 points (due October 15, 2026). Sole-source procurements appear frequently in the recent block, particularly for OEM-certified parts and manufacturer-exclusive equipment where operational continuity and permit compliance drive non-competitive awards.
