Dutchman Creek in Yadkin Pee -Dee River Basin
Previous CEI (Violation & Concerns
-weirs on 1 st clarifier not level Return and waste pum s in clarfier 1 need replaced
- circular well in clarifiers has significant sludge build-up; floating sludge and pin fpoc observed
- appearence of short-circuiting. (more flow going to 1st aeration basin than other two parallel trains)
-has rag screw at influent p/s been repaired? this reportedly contributed to a bypass of 1,500 gallor
occurring at bar screens on 12/15/2019. No
