UNSPSC 20101603: Drain hole screen

UNSPSC 20101603 Drain hole screen (Commodity) covers mechanically cleaned wastewater treatment screens supplied to municipal water authorities and environmental service agencies. State and local governments procure these screens as discrete equipment components for wastewater treatment plants, specifying performance criteria such as flow capacity, screen opening size, debris handling, and head loss, along with associated mechanical assemblies, drive systems, spray wash components, startup support, and training. The Maryland Environmental Service, a state-level environmental agency, represents the primary recent buyer in this code.

The Maryland Environmental Service issued an IFB (Solicitation 1262595) on April 28, 2026, for supply and delivery of a six-millimeter wastewater screen for the Dorsey Run Wastewater Treatment Plant in Jessup, Anne Arundel County, with a response deadline of May 28, 2026. The solicitation required bidders to attend mandatory site visits on May 6 or May 8, 2026, and mandated submission of shop drawings, load calculations, product data sheets, and references from five existing treatment plants operating the proposed screen system. The contract award was to be made to the lowest responsive bid; no budget was disclosed, and no set-asides or subcontract participation goals applied. Addendum No. 2 was issued prior to bid opening, and 17 plan holders registered interest in the opportunity.
