Calpine Broad River Energy Center Storm Pond Modification

Calpine contracted Keystone Constructors to build a new storm pond outfall structure that would help them contain any spills to the site and prevent them from getting to the Broad River. The team faced numerous challenges, which included scorching temperatures of 95+ degrees for almost the entire length of the project. There was also the challenge of getting the prefabricated sections to the site which was down a steep and narrow embankment. The team did an excellent job of constructing the structure while maintaining the environmental surroundings and working in a safe manner at all times. The project went off without a hitch and considering the obstacles faced it was a great team effort by Keystone!
