Data from the lab appeared to match the information listed on the DMR's. A new centrifuge has been installed to manage the sludge from the .VWVfP, and was being operated at the time of the inspection. Sludge is now trucked to the landfill, and the drying beds are no longer used except for storing the dried sludge until it can be carried to the landfill for disposal. The influent flow meter is used to record flow, and is calibrated by staff at the VVVVTP. The last calibration was conducted on May 1, 2013.
