Waste Treatment Plant

King's Thrones septage processing facility opened in 2016, making it easier for us to process septic waste pumped from local waste tanks. With this septage processing facility, we can separate the liquid from the solids, conforming to local sanitation requirements. Every batch of processed wastewater is tested to make sure it conforms to the City of Lewiston discharge limits for pollutants. The remaining biosolids are composted for use in fertilizers or composts.
