Work underway on fixing Elwha water treatment plant

(Port Angeles) -- A delay in the project to remove dams on the Elwha River. That as crews deal with clogging of the water intake for a treatment plant that serves industrial Elwha River water users.

Problems associated with the water intake structure at the treatment plant began last fall, when fish screens and pumps became clogged by high concentrations of organic material and sediment.

Olympic National Park's Barb Maynes says the problem only affects industrial water users, not residential water for the city of Port Angeles.

Two treatment plants were built as part of the dam-removal project to filter out increased sediment as a result of the the project.

The Park Service last week awarded a 1.3 million dollar contract to Macnak Construction of Lakewood to make the plant upgrades.

Removal of the two Elwha River dams is the largest project of its kind in U.S. history.

The lower dam has been removed and crews will start again soon on finishing removing the upper dam.

The project has been on hold for a recent fish window and also to allow time to deal with the water-treatment issue.

Maynes says new screens for the water-treatment plant should be in place by April.
