UNSPSC 39122328: Mercury relay

UNSPSC 39122328 Mercury relay is a Commodity code that in practice encompasses electrical control and switching equipment for water and wastewater infrastructure, though recent state and local solicitations show little activity directly under this narrow code designation. Instead, buying activity clusters around related motor control and electrical equipment procurement—Motor Control Centers (MCCs), control panels, programmable logic controllers, and soft-start replacement units—that state and local water and utility agencies are acquiring to upgrade aging infrastructure and maintain operational continuity. Issuing bodies include county water districts (Hillsborough County Board of County Commissioners, West Basin Municipal Water District, Bay County Board of County Commissioners), municipal water and wastewater departments (City of Tampa Wastewater Department, City of Santa Fe on behalf of Buckman Direct Diversion), and independent school districts (Northside Independent School District). One cooperative purchasing vehicle, Sourcewell on behalf of multiple Washington state counties, recently advertised law enforcement equipment but represents a procurement model available to state and local buyers seeking standardized contracting frameworks across jurisdictions.

Recent representative opportunities include Hillsborough County's ITB for pump station control panels and enclosures (ITB2600393, bids due September 29, 2026, $3.66 million estimated over two years, with ten contractors bidding and unit prices ranging $21,000 to $112,000), the City of Tampa Wastewater Department's intent to single-source Solcon Soft-Start replacement parts and services (solicitation 26X01899, due October 2, 2026), and West Basin Municipal Water District's Request for Bids for TRWRP 93 Motor Control Center Replacement (RFBTH0120, bids due April 23, 2026, mandatory pre-bid on March 12, 2026). Geographic concentration appears strongest in Florida (Hillsborough, Bay, and Polk counties; Tampa and Orlando municipal utilities) and California (West Basin in Los Angeles County), with additional activity in New Mexico (City of Santa Fe) and Texas (Northside ISD in San Antonio). The code shows sporadic rather than sustained recent solicitation volume; many recent opportunities nominally tagged under related electrical equipment codes involve motor control centers, SCADA systems, and PLC replacements for water treatment and wastewater pump stations rather than mercury relays specifically.
