Lebanon Water Treatment Plant

Slayden replaced the aging Water Treatment Plant (WTP) for the City of Lebanon, Oregon. This replacement includes the construction of a new intake on the South Santiam River; a new raw water pump station; a new water treatment plant; and raw water transmission, sewer, and stormwater pipelines. The new facility now has a capacity of 4.5 MGD, with the capacity to upgrade to 8 MGD.

The project’s facilities include a 14,000-SF water treatment plant pre-engineered metal building. The water treatment plant building enclosed the membrane filtration system, water treatment and chemical systems, electrical room, process equipment, feed and finished water pumps, and administrative offices. Other prominent site features included a new concrete settling basin and two glass fused to steel bolted water storage tanks for 25,000 gallons of raw water and 434,400 gallons of finished water storage.
