Description

The Town of Cary is seeking proposals from qualified control system integrators to design, furnish, program, install, test, and commission improvements to the supervisory and control system at the Swift Creek Pump Station. The project will replace and reprogram the existing control and monitoring system as the pumping system is converted from 575-volt to 480-volt power. The work aims to upgrade controls and integrate existing pump station equipment while increasing operational redundancy. Proposals are due November 5, 2026, at 10:00 AM; only vendors registered with North Carolina's Electronic Vendor Portal can submit a response.
