Midlothian High Service Pump Station and Clearwell
Client: City of Midlothian Public Works
Prime Engineer: Schrickel, Rollins & Associates, Inc.
In an effort to solve pressure and product deficiencies, the City of Midlothian financed improvements to its existing water system. The solution was an 8.0 million gallon per day (MGD) water treatment plant expansion consisting of a raw water pump station, a raw water pipeline and treatment water transmission pipelines.
Shrader Engineering teamed up with Schrickel, Rollins & Associates to design the electrical power, controls and instrumentation, SCADA, and security systems for a 13.5 MGD pump station (expandable to 18 MGD) for Phase 1 of the project, receiving water from the Tarrant Regional Water District conveyance lines.
The 5-megawatt electrical system provides power to the run variable frequency drive pumps. The SCADA system links to Water Plant No. 1, allowing complete control of the plant remotely via a 0.9-gigahertz radio system. Surveillance cameras and access control systems were also designed to allow cameras to be monitored at the remote water plant via a 5-gigahertz radio link.
To optimize operations management for the entire electrical, instrumentation and control system, Shrader designed a SCADA system with Ethernet PLC’s, linked to Invensys Wonderware HMI software – selected to provide high-quality graphic visualization. Programming of PLC’s and Wonderware was performed by Shrader’s Integration Engineers and Technicians.
