Slayden installed two new owner-furnished centrifuge dewatering systems inside an existing building that required significant structural upgrades to support the suspended centrifuges and bridge crane. Demolition of four existing belt filter presses and screw conveyors created the space necessary for new work. Structural improvements included installation of new structural concrete tables on a micropile foundation system to stabilize the structure and minimize vibration, ensuring reliable centrifuge performance. The project also required integration with existing solids-handling systems inside a constrained utility corridor while maintaining continuous dewatering through the one remaining centrifuge in operation. In addition, the indoor polymer system was upgraded for redundancy and improved polymer blending, and included installation of two new conical bottomed indoor storage tanks carefully lowered into a tight space from an upper level.
Slayden earned First Place in the 2025 AGC Construction Safety Excellence Awards (CSEA) in the Utility Infrastructure Category — Under 500,000 Work Hours.
