We met with Vince Edwards (ORC) for the inspection. The condition of the plant is no different from my previous inspection on 2/10/2020. The tertiary filters are still broken, the flow meter has not been replaced, the screening for rags is inadequate, and effluent sampling is still not flow proportional. The ORC has to climb down a ladder into the dechlorination tank in order to fill the tablet tube. There is no safety railing to prevent a fall into the tank. This is a safety hazard.

Are audible and visual alarms operable? # Is basin size/volume adequate? The equalization basin was not aerated. The ORC says that aerating the basin causes the pumps to clog. The equalization basin sometimes overflows during high flows and therefore is undersized. Comment: Aeration Basins Yes No NA NE Mode of operation Ext. Air Type of aeration system Diffused Is the basin free of dead spots? Are surface aerators and mixers operational? Are the diffusers operational?
