Clearing the obstacles



Jeffery’s Energy Wetlands

This project took over 150,000 man-hours to complete, and it was completed on time without any safety incidents. It consisted of constructing five cells that included two equalization ponds, two flow bed cells and a single vegetated submerged bed cell. The project included 38,000 CY of topsoil stripping, 42,000 CY of rock excavation and 335,000 CY of gypsum that was imported from an onsite landfill.

The cells required a 145,000 CY of clay liner, then 1,000,000 SF of HDPE Liner and 25,000 LF of HDPE piping within the cells. The cells were then filled with 150,000 CY of a sand/soil mix, 85,000 tons of aggregate, 41,500 CY of topsoil and 16,000 CY of sand, all part of a natural filtering system to clean the cooling water. The project won EEI The project won EEI’s 2014 Edison Award, Power Plant Magazine’s 2014 Water Award and ENR’s 2015 Best Projects Award.
