  • Automation and control systems upgraded to more robust, modern systems
  • Higher quality water, reduced chemical use, and operational cost savings.

The Raritan Millstone Water Treatment Plant, in conjunction with the New Jersey American Water Canal Road Water Treatment Plant, delivers high-quality water to 1.3 million people in eight New Jersey counties. Located at the confluence of the Raritan and Millstone Rivers, the plant produces 165 million gallons of finished water per day. As part of a $40 million improvement plant, Gannett Fleming is designing upgrades to the plant’s instrumentation and controls systems, ensuring that water continues to flow efficiently to area residents.

What We Did

For the automation study, Gannett Fleming surveyed the existing automation and control systems, which included several generations of Allen Bradley SLC controllers that were partially interconnected with ad-hoc legacy networks. Gannett Fleming’s instrumentation engineers developed several possible system architectures that allowed the client to select between preserving their existing controls investment or upgrading to a more robust, modern, and future-proof system. The firm assisted the client in selecting an option that best met their funding and operational goals and delivered a plan for implementation. The far-reaching SCADA upgrades involved 65 remote distribution system sites.
