Dewatered solids loading will now be contained within a new Dewatering Building, reducing associated noise. All chemical deliveries are internal to plant facilities,Where possible, all equipment screening associated visuals and noise. Delivery points are Existing basins will no longerthat is traditionally external to be used for solids drying.buildings (HVAC fans, mixer designed with spill containment measures. Current noise associated withmotors, etc.) will be located solids drying activitieswithin buildings to reduce (engines, “backup” beeping,external noise. etc.) will no longer be needed at the plant. The remaining two lagoons will only be used during emergency operations. Mapleton Dr.

  • 18. Benefits for West LinnWest 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.
