Slayden served as the CM/GC for the City of Salem’s Geren Island Water Treatment Plant Filter No. 2 Reconstruction project. Originally built in 1970, Filter No. 2 had reached the end of its useful life, and the project was completed to increase treatment capacity, improve reliability, and provide added flexibility for removing turbidity and filter-clogging algae.
During preconstruction, Slayden worked with the City and design team to evaluate constructability, sequencing, cost, schedule, and procurement strategies for completing major filter improvements within an active drinking water treatment facility. The team focused on maintaining plant operations, preserving treatment capacity, and coordinating the work around seasonal demands on the water system.
Construction included reconstruction of Filter No. 2 and related roughing filter improvements, with associated mechanical, piping, controls, and tie-in work required to integrate the upgraded filter into the existing treatment process. The completed improvements strengthened the City’s long-term water treatment reliability and improved operational flexibility at the Geren Island facility.
Slayden earned First Place in the 2025 AGC Construction Safety Excellence Awards (CSEA) in the Utility Infrastructure Category — Under 500,000 Work Hours.
