Operator training underway on the new ozone system

Water Treatment Plant Construction Update

On Thursday, the third and final crane that was used for construction was dismantled and removed off-site. As construction comes to a close, more equipment and materials will be leaving the site.

In mid-April, crews expect to remove the large construction trailers currently located on the western corner of the site. Removal is expected to take about a week. A small trailer will be present for the remaining work, near where the carpenters' shed was located on the west side of the site.

Lake Oswego-Tigard Water Partnership inviting neighbors to its garden

by Patrick Malee, The Times - March 26, 2017

In the news...

After four long years of construction, the end is finally in sight this summer for the Lake Oswego-Tigard Water Partnership (LOT) water plant.

To describe the atmosphere of relief at the construction site as "meditative" might be a bit much, but that time will come with some help from the LOT itself. As construction in West Linn's Robinwood neighborhood nears its projected end date in early June, the partnership — a joint endeavor between Tigard and Lake Oswego to provide a source of drinking water for both communities — is working to install a stormwater basin that will double as a "meditation garden" for residents to enjoy while passing through the site.

The Lake Oswego-Tigard Water Partnership, which began supplying drinking water from the Clackamas River to Lake Oswego and Tigard last year, is designed to serve as the primary water supply for both cities.
