The other thing we learned was that we need to be far more careful about what goes in the sewer system. Paper towels, baby wipes and hand towels do not deteriorate in the sewers. No matter what manufacturers claim, you find them everywhere and they look just like they did when flushed. They clog lift station pumps and pipelines. Do not put these down the toilet for any reason? Likewise there are no feminine hygiene products that should be flushed, ever! Again regardless what the manufacturers claim, you can find there ubiquitously in the sewer system and they look, well just like they did when flushed. No biodegradation. I have included some figures. They show up in pump clogging and at plants as well. They are not biodegradable. Again do not put these down the toilet! Put all these products in the trashcan in the bathroom.
Worse, do not put grease down the drain. One photo is a greaseball in a manhole. It fills the whole manhole up! Of course the feminine hygiene products, towels, wipes, etc. plus grease make almost impenetrable obstacles that block the sewer system. So we need to remove the inflow and we need to keep grease and the reset of these products out to reduce the costs of operating the wastewater utility. We all contribute, and we all can help. We want systems to operate properly and dependably, so let’s do our part.
