Heber Pud Wastewater Treatment Plant Scada And Computers Upgrade

The Heber Public Utility District has issued a Request for Proposals for the SCADA and computer system upgrade at the Heber Wastewater Treatment Plant in Calexico, California. The primary objective of this project is to replace obsolete Windows 7 computers and legacy PLC hardware that are failing due to a corrosive, gassy environment. Key technical deliverables include migrating legacy Allen Bradley SLC-500 controllers to the newer CompactLogix 5380 family, importing RS Logix 500 applications into Studio 5000 Logix Designer, and upgrading Aveva Wonderware licenses to the Aveva System Platform 2020. Additionally, the project requires the procurement of two Dell Precision desktop computers running Windows 10 Professional within a VMWare Workstation Pro 16 virtualized environment to ensure system redundancy. The contract will be awarded to the lowest, responsive, and responsible bidder. To qualify, bidders must hold a valid California Class C-10 Electrical Contractor license and demonstrate experience in performing work of a similar nature, type, and magnitude over a period of at least 10 years. As this is a public works project, all work must strictly comply with California Labor Standards, California Labor Codes, and prevailing wage requirements. Successful bidders must also provide insurance documentation and a one-year warranty for the completed project. Proposals must be submitted via the official Proposal Form and include an Experience Statement, with a final response deadline of October 21, 2026, at 3:00 P.M. PST.
