Collaborative Approach to Systems Integration Transforms Plant Operation

Wastewater Treatment Plant Expansion, Power Supply, SCADA & Technology Integration

Sangamon County Water Reclamation District - Spring Creek Plant | Springfield, IL

A key feature of the $125 million expansion and modernization of the Spring Creek plant design was to usher in the advantages of digital age technology. Crawford, Murphy & Tilly (CMT) led a technology integration approach through the design process that transformed plant operations resulting in higher level of optimization, efficiency and flexibility.

CMT led the systems integration design for what is essentially a fully-automated facility. The project included a new supervisory control and data acquisition (SCADA) to integrate with a computerized maintenance management system (CMMS). Other technical features include data and communications network with a new fiber service, digital security, proximity cards and a VOIP telephone system. CMT also led the electrical system design which included new dual medium voltage service entrances, medium voltage loop distribution for redundancy, power distribution, lighting, and motor control layout.

CMT with support of consulting partner SCADAware drove the design process resulting in a complete SCADA system consisting of over 45 PLC’s, 30 HMI’s, and several different SCADA computers along with network communications infrastructure. A highly collaborative approach with the client was used to allow input in the design process as well as the final integration of the SCADA system.

Time and consideration was taken in the controls description as well as the functionality of these units, the reporting with laboratory testing inputs, trending of systems and finally remote alarm annunciation of the facilities. Due to the number of inputs and output for the operation of pumps, gates, valves, instrumentations a Profibus system was utilized as the main form of communication. CMT, along with SCADAware, provided input in the new computing system platform, computer historian, and a disaster recovery plan.

The project team recognized that adjusting to the technologies in the modernized facility would be a significant change compared to the manual operations of the old facility. Training support was provided to help the plant staff in that process and ensure a smooth transition. With the new technology in place staff is now able to make more data-driven decisions to continue optimization of the plant’s operations.
