The H.D. Taylor Water Treatment Plant (WTP) in Corvallis, Oregon, is a conventional plant located on the Willamette River. The original Willamette River WTP was designed in 1949 and had a nominal capacity of 4 million gallons per day (mgd). The plant was expanded to 8 mgd in 1960 and further expanded to 21 mgd in 1970 with the introduction of high-rate tube settlers and mixed media Microfloc filters. With the 1986 amendments to the Safe Drinking Water Act, the plant capacity was derated to approximately 14 mgd. Because of sedimentation limitations and the age of the filters, the plant capacity was further derated to 11.2 mgd to establish the current project design capacity. This paper discusses the upgrading and expansion of the H.D. Taylor WTP. Startup testing and optimization of the new plant are also addressed.
