The South Carolina Department of Transportation is issuing an Invitation for Bid for a two-year polyethylene brine tank purchase agreement for District 1, with the procurement managed by Richland County on behalf of multiple jurisdictions including Kershaw, Lee, Lexington, Richland, and Sumter counties. The solicitation seeks a supplier to provide and deliver 5,500-gallon CAPTOR Containment System tanks designed for brine or calcium chloride storage at various county maintenance locations. The primary tanks must be constructed from high-density polyethylene (HDPE) using rotationally molded, one-piece seamless design with a hydrostatic design stress of 660 psi at 73 degrees Fahrenheit, compliant with ASTM D 1998-21 standards, and must include secondary containment tanks with a minimum capacity of 115 percent of the primary tank in compliance with 40 CFR-264.193. Each tank assembly includes an 18-inch threaded manway with vented center cap, 2-inch PVC bulkhead fittings, an 18-inch polyethylene mushroom vent with bug screen, and associated stainless steel hardware. The contract requires the supplier to provide comprehensive engineering services including pre-installation site visits within 24 hours of notification, post-installation compliance verification, and emergency on-site support within 24 hours of notification, with all field service costs included in the base tank price. The bidding schedule identifies two line items: twenty tanks at a unit price to be determined and ten delivery fees representing two tanks per county maintenance office, with all deliveries required within four months of purchase order receipt and approximately 12 weeks from purchase order receipt to tank delivery. The bid opening date is March 19, 2026, at 2:30 p.m., with questions from offerors required by March 11, 2026, at 12:00 p.m., and award notification scheduled for April 1, 2026. No pre-bid conference or site visit is required, and the contract period runs from March 30, 2026, to March 29, 2028, with an initial one-year term and automatic renewal for an additional one-year period unless the State provides thirty days' notice of non-renewal.

The solicitation does not identify any set-aside designations or restrictions limiting the types of organizations that can respond, nor does it reference any disadvantaged enterprise requirements or incumbent vendors. No current contractor or existing infrastructure integration requirements are specified in the available documentation. Prospective bidders must submit one online copy of their signed offer through the South Carolina procurement website at http://www.procurement.sc.gov and acknowledge receipt of Amendments 1 and 2 through one of four specified methods.
