19. Benefits for West Linn
West Linn’s Water Supply
Oregon City and West Linn jointly own South Fork Water Board (serves
s
54,000 people).
Drinking water source: Clackamas River
Treatment plant located in Oregon City in the Park Place
Neighborhood. (Recently extensively upgraded and expanded).
Water delivered through a 24-inch transmission main suspended on
the I-205 Bridge.
Benefits of Partnership
Lake Oswego’s water treatment plant serves as West Linn’s sole
emergency and backup water source.
The water treatment plant cannot deliver emergency supply year-round unless it is expanded through
the partnership with Tigard.
West Linn’s Water Master Plan (2008) explains West Linn does not currently have adequate storage to
meet system-wide needs under emergency conditions.
Improving the intertie with Lake Oswego is identified as the least expensive option to meet storage
supply needs.
West Linn ratepayers would save millions of dollars by avoiding construction of a new 8.4 million gallon
reservoir.
A larger underground reservoir for treated water (a clearwell) at the plant will allow water to be fully
treated before it leaves the treatment plant – a key to providing high quality potable water to West Linn
residents when needed.
