Collaborative Approach to Systems Integration Transforms Plant Operation

A key objective of the $125 million expansion and modernization of the Spring Creek Wastewater Treatment plant design was to usher in the advantages of today’s technology. Crawford, Murphy & Tilly (CMT) led a technology focused approach through the design process that transformed plant operations, resulting in a higher level of optimization, efficiency and flexibility.

CMT led the systems integration design for what is now 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 included a data and communications network with a new fiber service, digital security, proximity cards and a voice over IP telephone system. CMT also led the electrical system design which included dual medium voltage service entrances, medium voltage loop distribution for redundancy, power distribution, lighting as well as 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.

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 plant staff 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.
