Project: Lake Texoma Pump Station Improvements
Date: July 2016
Since 2009, NTMWD hasn’t pumped raw water from Lake Texoma. Five Star Electric, working with T-Star Engineering and Northeast Power Solutions, has assisted with increasing pumping capacities from Lake Texoma thru the installation of a SVC-Static VAR Compensator. Medium Voltage Dynamic VAR Compensation Systems greatly improves substation or plant power quality. Their main goal is to resolve power issues such as voltage “Flicker” and “Sag” due to weak power supplies or motor starting.
An SVC (Static VAR Compensator) is placed on an entire bus, and compensates for all loads on that bus – including multiple motors of different sizes. Like a VFD, it remains online constantly, correcting for all load changes, not just motor starts. After installation of the pump station the motor or load curves were off, thus not allowing the motors to start. The solution Five Star Electric offered was to stiffen the system. Using the equipment that was currently installed and adding a 1500 kVAR capacitor banks to the system when starting to reduce the magnetizing current drawn from the Utility. The medium voltage metal enclosed SVC are an economic, compact and easy to maintain source of reactive power. The Static VAR Compensator are customer built to the requirements desired and shipped fully tested, assembled and ready for interconnections. They contain all switching, protection and all control.
Adding the SVC has assisted NTMWD in increasing pumping capacity from Lake Texoma to allow greater flexibility in the pipeline operation.
Project: VFD with VFD bypass
Date: June 2015
Five Star Electric (FSE) prides itself on being a turnkey integrator; we’re proud to work with mechanical contractors who represent many different VFD manufacturers. Since HVAC is critical business in Texas, it’s necessary to have reliable systems. Some VFD packages require a mechanical bypass to ensure the air handler continues to run and not all VFD manufacturers are capable of configuring a customer specific application. If a special enclosure is needed (NEMA 4X, 12, 3R, etc.), FSE is able to take a customer supplied VFD and integrate per the customer specification.
The following application was designed for a local high school, where the contractor had to supply VFD’s with a VFD bypass. This is an unusual request since most bypass systems are mechanical. The operation required FSE to engineer a solution for VFD #1 to automatically switch to VFD #2 when #1 fails. The project required redundant 3hp, 10hp, and 25hp. The 3hp required a 36”x36”16 NEMA 4X 304SS enclosure, 10hp 42”x36”x12” NEMA 12, and 25hp 60”x36”X16” NEMA 12. Additionally, a rush turnaround time for this particular project was needed in order to maintain extremely critical construction schedules. FSE utilized its FASTRAX program to take this custom project from inception to delivery in less than 6 weeks. Most large manufacturers fail to provide the flexibility to make something like this happen in such a limited amount of time; but FSE remains extremely flexible despite its growth, and will always take the extra steps to get the job done. Our customers always come first. This has been, and will remain to be, our business model.
Project: Irrigation Pump Skid
Date: February 2015
Five Star Electric (FSE) is proud to have an integral role in upgrading the irrigation pump control system for a local theme park in San Antonio, Texas. FSE is providing a turn-key solution to make the system more efficient in order to reduce overall operating expense. Due to the size of the process and proximity of the park, it is critical for this application to work seamlessly on its own. The system consists of five VFD’s (10HP, 25HP, 50HP, 75HP, 100HP) which will significantly reduce the energy costs required to operate the system compared to the original full voltage starters being replaced. In addition to the VFD’s, FSE will also be automating the process to be more self-containing.
Five Star Electric (FSE) manufactured all the VFD’s and PAC Control Panel at their San Antonio Texas Plant. FSE Service group will be providing all the installation and commissioning services, in addition to customer support for the entire system.

Project: Galveston Main Wastewater Treatment Plant
Date: June 2012
2011 Be Inspired Award Winner – Innovation in Water and Wastewater Treatment Plants Five Star is teaming up with Invensys/Foxboro to provide an integrated solution for the Plant Automation/Instrumentation control system.
Located on a barrier island off the Texas Gulf coast, Galveston was devastated by Hurricane Ike in 2008. The extended storm surge caused a major portion of the public wastewater facilities including the 10-million-gallon-per-day Main Wastewater Treatment Plant to fail to function. Design of the $75.4 million project to rebuild the plant was completed in less than a year to help ensure federal block grant funding eligibility.
The scope included modifying screening structures; rebuilding an influent lift station as a submersible pump station; rebuilding the grit-removal system; replacing aeration basins, air diffusers, and blowers with a sequencing batch reactor; converting the disinfection system to ultraviolet disinfection; constructing an intermediate pump station; and modifying the solids dewatering building.
CDM constructed a 3D/4D model of the seven facilities using original drawings and field surveys. Intelligent modeling drove the integrated design process from front-end engineering and design through phased construction. ProjectWise facilitated management of more than 8,800 documents for 162 team members in 22 offices. Using 3D/4D models shortened client and regulatory review time by 25 percent and reduced design time by 30 percent.
