Two filters are backwashed approximately every 60 hours in the winter and approximately every 100 hours in the summer. This depends on Ivy River water quality which the ORC said has improved over time. Solids Management: Weaverville currently employs Bionomics annually to manage solids. Bionomics was last onsite for approximately 2 weeks in August -September 2021. The company set up a belt press system onsite and hauled a daily load each day to the County landfill. Weaverville is considering an expansion in the future at this facility, as well as extending the discharge line down the road. Records are well organized. ETS is the laboratory used by Weaverville, ETS contracts Metals work out. Metals results are reported by the laboratory in mg/I, the ORC needs to convert the Metals result values to ug/I for DMR reporting. Calcium Thiosulfate liquid is used for de -chlorination. The facility has a Compliance Schedule (Compliance Action Plan CAP) for Copper (Cu). The first annual CAP is due 1/2/2022.
