South Fork’s current water system includes the water intake just off of Clackamas River Road, a pipeline up the hill from the river to the site of the water treatment plant, a transmission pipeline from the treatment plant to Oregon City and West Linn distribution connections, and a pump station to boost treated water to higher elevation of both Oregon City and West Linn.

The purpose of water treatment is to purify the surface water of the Clackamas River and to remove objectionable or detrimental materials and to produce a high quality safe water for domestic consumption.  The treatment plant capacity is approximately 20 million gallons a day (MGD) and the peak day to date was 19.8 mgd in summer of 2003.
