QUICKLIME

Board of County Commissioners · 2026-07-21 · resolution

Miami-Dade County Board of County Commissioners (BCC) is considering the approval of Contract No. EVN0013501, "QUICKLIME," for the Miami-Dade Water and Sewer Department (WASD). The contract is proposed to be awarded to Carmeuse Lime & Stone, Inc. for a five-year term at a total cost of $124,080,000.00. This contract is for the supply of quicklime, a critical chemical used in water treatment for softening, pH adjustment, and alkalinity control. WASD requires approximately 42,000 tons annually to supplement its own lime production and ensure continuous operations at its three regional water treatment plants: John E. Preston, Hialeah, and Alexander Orr. The contract requires quicklime to meet stringent quality and regulatory standards, including a minimum 90 percent calcium oxide (CaO) concentration, conformance to AWWA Standard B202-25, and certification under NSF/ANSI Standard 60. The contract will replace Contract No. FB-01772. The Infrastructure, Innovation & Technology Committee forwarded this item to the BCC with a favorable recommendation on June 10, 2026. The contract award is scheduled for the BCC Agenda on July 21, 2026.
