Chesnee, NC

 R.B. Simms and Lake Blalock are the largest water treatment facilities for Spartanburg Water (SW), providing service to nearly 200,000 residents. SW selected Crowder as Design-Builder to design and construct the needed improvements to their aging plants. The major goal was to improve reliability and maintainability of the electrical system while minimizing impacts to ongoing operations during construction. Crowder coordinated with Duke Energy on all activities associated with establishing a new utility substation for the delivery of 4160V 3-phase electrical power to the WTP, as well as coordinating with local authorities to ensure the new installation was in accordance with all applicable codes. This was a large-scale D-B project on a 19-acre site.
