STRATEGIC ALIGNMENT
This action supports Key Focus Area: Enhance Infrastructure and Mobility.
INFORMATION/BACKGROUND
The Ray Roberts Water Treatment Plant (WTP) utilizes ozone gas as a primary disinfectant during the water
treatment process. The ozone is produced by generators that are original to the facility, which was
constructed 23 years ago. These generators are controlled by a Master Ozone Control Panel (MOCP), which
functions as a Programmable Logic Controller (PLC) by communicating with the generators and regulating
their operation based on setpoints provided by plant operators.
The communication hardware and interface cards that support this system are now obsolete, and
replacement parts are no longer available. In the event of a component or communication failure, the ozone
generation process would fail, resulting in the plant's inability to treat water until repairs are completed.
Given the critical role of ozone in the disinfection process, the aging PLC system represents a significant
operational risk.
This project will upgrade the obsolete PLC hardware and communication systems with modern components
that are supported by current technology and for which replacement parts and technical support are readily
available. This investment will ensure continued reliability and regulatory compliance until a future plant
expansion is completed.
