This inspection was conducted to determine if the system is being operated and maintained in compliance with permit no. NC0080659. Jo Davis (Maintenance), Andy Greg (Director of Operations and Maintenance), and Randy Joseph (ORC) were present during the inspection. The 0.009 MGD WWTP accepts flow from two neighboring schools – Madison Middle and Brush Creek Elementary, with individual grease traps for each school. The flows combine into a septic tank which delivers flow to the two recirculating sand filters. The plant is designed to re-circulate flow at a ratio of 3 to 1 prior to tablet chlorination and dechlorination. At the time of the inspection, one pump which delivers water to the sand filter from the septic tank was out of operation. A fuse was changed following the inspection and both pumps were verified to be operational. Additionally, the flap valve on the effluent discharge pipe was not present and sediment was observed in the dechlorination chamber, indicating that backflow was occurring. A new flap valve was added following the inspection. NC0080659 17 (Cont.)
