Ultraviolet Sanitizing System Online

In order to achieve new regulations around fecal coliform limits at the Industrial Wastewater Treatment Facility, the Port selected an ultraviolet (UV) disinfection process. The limits are outlined in the current National Pollutant Discharge Elimination System (NPDES) permit through the Department of Ecology.

 The new UV system works by shining light through clear basins as effluent travels through them. This effectively cleans and sanitizes the wastewater, making it ready for final disposal.

 While a majority of the work building the new system was able to continue throughout the year, there were delays in the delivery of supplies for the project due to COVID-19. However, the project was still able to be completed before the compliance deadline of May 27, 2020.
