Local lawmakers attended the ribbon cutting of the BioFiltro wastewater treatment facility at the Royal Dairy in Royal City Washington. It’s the largest dairy wastewater treatment facility in the nation and will treat 200,000 gallons of water each day through an organic filtration process which ultilizes worms to treat the wastewater and produce irrigation grade water along with organic fertilizer and animal feed protein.
The system, according to BioFiltro, reduces greenhouse gases by 90 percent.
Washington state representatives Shelly Short and Joel Kretz were present for the ribbon cutting of the 81,000 square-foot facility which began operation on Aug. 7.
