Industrial Wastewater

Wastewater Discharge GraphicDid you know that industrial wastewater requires 'pre-treatment' before leaving the Port of Longview?

The Port handles a wide range of imports and exports and part of our commitment to excellence and environmental stewardship is treating industrial wastewater. As such, we have three berths that are contained into wastewater treatment, Berths 2, 5 and 7.  After initial pre-treatment, the industrial wastewater is conveyed through the City of Longview or Cowlitz County's sanitary sewer to Three Rivers Regional Wastewater Plant. 

Since 2015, when the Port improved the industrial wastewater pond, we have increased pre-treatment volumes by triple the 2014 numbers. The graph to the right illustrates the total annual volume of wastewater pre-treatment at our Berth 7 pre-treatment facility.
