Jones|Carter worked alongside the City of College Station to replace and upgrade existing motor control centers and their associated feeders at the Carter’s Creek Wastewater Treatment Plant. These improvements allow for greater reliability and easier procurement of spare parts.
The team designed electrical upgrades, which consisted of replacing the existing main switchgear (MS) south and Motor Control Center (MCC)-A and MCC-C with smart Switchgear and MCCs. The team also designed a proposed distribution system to communicate with the existing plant SCADA system. The replacement MCCs were installed with canopies over them for protection from the sun and to reduce internal heat, which will extend the life of the components. Local blower control panels were also added to the blowers fed from MCC-A and MCC-C.
The J|C team replaced 4,500 linear feet of duct bank and conductors associated with MS-North, MS-South, MCC-A, MCC-B, MCC-C, MCC-D, and MCC-E. This required working around existing underground utilities. The team also replaced the existing centrifuge control panel and back drive to update the centrifuge and extend its life.
During design, J|C performed duct bank mapping to limit conflicts that could delay construction. J|C developed a detailed sequencing plan to ensure continued operation of the plant while the MCCs, ductbank, and wire is being replaced.
