Slayden partnered with the City of Medford to significantly expand the wastewater treatment plant’s capacity and reliability, more than doubling its ability to manage secondary treatment flows. The project included the careful demolition and replacement of equipment across five 90‑foot clarifiers, along with the installation of five new vertical turbine pumps housed in 30‑foot pump cans. Slayden also built a new CMU chemical storage building equipped with two WAS pumps, installed roughly 1,200 feet of new RAS piping, added five sluice gates, and upgraded the mixed liquor channel with new air diffuser piping. Together, these improvements strengthened the plant’s performance and ensured the community’s wastewater system is ready to support future growth across the Rogue Valley.
Slayden earned First Place in the 2025 AGC Construction Safety Excellence Awards (CSEA) in the Utility Infrastructure Category — Under 500,000 Work Hours.
