7:39 PM: We just got back from the treatment plant to investigate the increased smell lately. While there, we discussed the smell with our operator, and he is aware of it, has been, and is addressing it. It will be gone soon.
If you care to know the science of what's happening, here's a short explanation: Every year, when spring hits and temperatures rise, fats, oils, and grease (FOG) become less viscous and, thus, enter the wastewater system sort of in a "rush." When they get to the treatment plant, they coat the microorganisms that normally do all the treatment of the wastewater. It's almost like COVID for a sewer plant. This coating reduces oxygen transfer and disrupts normal aerobic biological processes. This causes oxygen levels in the system to drop, and when oxygen levels drop, the system shifts to anaerobic conditions, which causes increased production of hydrogen sulfide gas, which causes the odor. We are correcting this by increasing aeration, breaking up and removing oils, and rebalancing the microbial system to restore proper aerobic treatment. This is a routine, seasonal condition that is being actively managed, and the odor will subside as normal conditions are restored. Overall, sewer plants are like never-ending science experiments where the operator is constantly adjusting to keep everything in line.
Summary: This is normal, and the smell will be gone soon.
