Stayton Wastewater Treatment Plant Improvements

Slayden was selected for this $9 MM plant expansion project for the City of Stayton. The project included construction of a new selector cell, filter structure, sludge drying and storage building, sludge storage tank, UV building over existing open channels and a shop. Specific new equipment included a sludge dryer, three-belt belt filter press, odor control unit, cooling tower, floating aerator, submersible mixer, three bays of cloth filters, screw conveyor and belt conveyor. Existing equipment that was removed and replaced included two channels of a UV system, two 11,000 GPM SBR mixing pumps, two turbo blowers, eight 24” valves with electric actuators, and two rotary lobe pumps. All of the equipment was removed and replaced under strict shutdown requirements in order to keep the existing plant’s processes operational.

All of the underground piping and connections were completed by Slayden. This included multiple connections to active waste activated sludge and secondary influent lines. Slayden also managed the complex process of integration of all electrical, instrument, and control packages with the existing system, along with start-up of the facilities. Close coordination with the existing plant operation, plant operators, and design engineer made this a successful project that was completed on time and with no interruptions to service.

Total Project Value: $8,979,613
