Redundant Water Supply Project
Summary
The City has over 56 miles of potable water piping in the water distribution system. The average daily water demand is about 2.4 million gallons per day (mgd) and the maximum day demand is approximately 4.5 mgd in summertime. The City’s current water supply is drawn from groundwater production wells located in the City’s well field on the south side of the Willamette River in Marion County. The well field is accessible from Riverside Road, off Champoeg Road and Highway 219.
The Water Master Plan notes that the City’s system is vulnerable to flooding, ground movement, seismic activity or other natural disasters. It was recommended that the City assess redundant supply options on the north side of the Willamette River. The redundant source, piping and treatment system should supply a capacity of one day of wintertime average daily demand. The current wintertime average daily demand is approximately 2 mgd. The Master Plan evaluated the expansion of a ground water source in Appendix C of the plan. Other options may include a surface water source, and interties to other nearby potable water supply systems.
