Helping Preserve and Protect the Elwha River Water Supply and Endangered Salmon

The National Park Service needed to remove two dams that were dramatically reducing adult salmon spawning by blocking fish passage on the lower Elwha River.

Over the course of this multi-term contract, Veolia has provided 24/7 O&M of the treatment and transfer facilities, including the Elwha Surface Water Intake, two fish screens, a diversion pump station, distribution vault structure, chemical and physical treatment systems, and a Supervisory Control and Data Acquisition (SCADA) system for remote reporting and operations.

“We are very grateful to ... the employees of Veolia for their skill and diligence in keeping the plant functioning during challenging circumstances."

– Sarah Creachbaum, Olympic National Park Superintendent
