Slayden served as the CM/GC for the City of Bend Water Reclamation Facility Solids Handling Improvements project, which was completed to improve the reliability, performance, safety, efficiency, and operability of the facility’s aging solids handling process. The work addressed deteriorated infrastructure within the existing solids handling building and replaced dewatering and polymer equipment that had ongoing maintenance and performance issues.
During preconstruction, Slayden worked closely with the City and design team to evaluate sequencing, constructability, cost, and operational impacts within the active treatment facility. A key outcome was a plan to install a temporary belt filter press outside the existing building, allowing the City to maintain full solids handling capacity while Slayden retrofitted the existing solids area and constructed the new polymer/electrical building. This approach shortened the schedule from 18 months to 12 months, reduced costs, and allowed construction to proceed without disrupting plant operations.
The constructed scope included selective demolition of the existing belt filter press, polymer system, piping, and electrical systems; installation of two new dewatering centrifuges, progressive-cavity cake pumps, grinders, polymer blending systems, and related process piping; relocation of the thickening polymer unit; construction of new polymer and electrical buildings; installation of transformers, MCCs, VFDs, controls, instrumentation, valves, strainers, and supports; yard and grading improvements; and recoating of existing structural steel. Throughout construction, Slayden maintained continuous solids processing, so the facility remained fully operational and compliant with discharge requirements.
Slayden earned First Place in the 2025 AGC Construction Safety Excellence Awards (CSEA) in the Utility Infrastructure Category — Under 500,000 Work Hours.

Slayden Constructors and Jacobs Engineering recently completed a $78 million expansion of the Robert A. Duff Water Treatment Plant for the Medford Water Commission. The project boosts capacity from 45 to 65 million gallons per day and adds advanced filtration, a new reservoir, a modern pump station, and seismic‑resilient redundancies. This upgrade strengthens long‑term water reliability for Medford and the greater Rogue Valley, supporting regional growth and public health.

Slayden’s Jeff Wall recently achieved a unique milestone. At the Pacific Northwest Clean Water Association (PNCWA) conference in Spokane, Washington, Jeff became the first contractor to be chosen under the PNCWA to join the Select Society of Sanitary Sludge Shovelers, also known as the 5S society. Members are selected based on “outstanding, meritorious service above and beyond the call of duty.” As recognition for this achievement, Jeff received a one-of-a-kind -5S gold shovel award.
