UNSPSC 23152108: Punch plate vibratory separation screen

Separation equipment screen based on punch plate action

UNSPSC 23152108 Punch plate vibratory separation screen (Commodity) describes equipment used in water and wastewater treatment to remove solids and residuals, though recent state and local solicitations show limited activity directly tied to punch-plate screening. The three most recent opportunities in the block address water treatment residuals removal and disposal (Clayton and Columbia counties in Georgia), mechanically cleaned wastewater screening (Maryland Environmental Service at Dorsey Run Wastewater Treatment Plant), and a replacement drive shaft for water treatment equipment (City of Holly Hill, Florida). Of these, only the Maryland solicitation explicitly requests a mechanically cleaned wastewater screen with defined specifications (6-millimeter opening, 4.8 million gallon-per-day peak flow capacity, heavy debris handling). The Georgia opportunities focus on removal and disposal of settled residuals rather than screening equipment procurement. Issuing bodies include county water authorities, state environmental agencies, and municipal water treatment operations — the mix typical of municipal water and wastewater infrastructure procurement.

Geographic activity centers on the Southeast: Georgia (Clayton and Columbia counties) and Maryland (Anne Arundel County) posted solicitations in mid-2026, while Florida's Holly Hill procurement closed in 2020 and is outside current activity. The Maryland Environmental Service's IFB for mechanically cleaned wastewater screening (Solicitation 1262595, due May 28, 2026) remains the most relevant recent opportunity under the code's nominal scope, requiring bidders to attend mandatory site visits on May 6 or May 8, 2026, submit shop drawings and equipment references, and deliver equipment meeting precise flow and debris-handling specifications. The Clayton County RFP 2026025-RFP5105 (due July 30, 2026) and Columbia County RFP PE63600NONST2026000000099 (due July 30, 2026) address residuals removal and disposal operations rather than screening-equipment supply. Overall procurement volume and repeat issuing bodies under this specific code are not evident from the recent opportunity block; screening and separation equipment solicitations appear episodic rather than a consistent procurement stream.
