Partnership files a pre-application for pipeline to cross the river to WL

The Lake Oswego-Tigard Water Partnership has filed a pre-application to the city of West Linn for the installation of a new pipeline to run from Gladstone through Mary S. Young Park and into the existing plant in West Linn.

A pre-application conference will be held with city staff Jan. 5 at 10 a.m. to go over the application, according to Assistant City Manager Chris Kerr. Notices will be sent to affected neighbors.

Lake Oswego has operated a water treatment plant since 1968 in the Robinwood neighborhood between Kenthorpe Way and Mapleton Drive. In cooperation with the city of Tigard, Lake Oswego wants to expand the plant and run a new pipeline to address the future water needs of both cities. The construction is expected to take 28 months.

To get the water to the plant, the partnership needs to run a new upsized pipe from the Clackamas River. The current pipeline runs through Mary S. Young Park, which is a stated-own park.

According to the pre-application form, 'The applicant proposes to construct a water pipeline from Mary S. Young park to its water treatment plant in the Robinwood Neighborhood and up Highway 43 to the Lake Oswego city limits.'

Except for Mary S. Young, the pipes will be contained within public right of way using open-trench techniques.

The proposed plant site includes several buildings clustered together near Kenthorpe Way, a walking path along one side of the site, landscaping and fencing options. The expansion will increase the plant's capacity from 16 million gallons of water day to up to 38 million gallons a day.

The plant, which will hold up to three million stored gallons of water underground, also serves as an emergency backup water supply for West Linn. Under an existing agreement with Lake Oswego, West Linn has an intertie at Old River Road and Kenthorpe Way that the city can tap into in an emergency, such as a major fire. West Linn hopes this access to emergency water will continue with the new Lake Oswego/Tigard partnership, thus relieving West Linn from building its own.
