Cesspit

A cesspit is like a really, really big toilet that is filled with poop and other yucky stuff. It's usually underground and can be found in some older houses or buildings. When people flush the toilet or use the sink or shower, all the water and waste goes into the cesspit. Over time, the poop and stuff builds up and makes it really stinky and gross. Someone has to come and take all the yucky stuff out of the cesspit so it doesn't overflow and cause problems. It's kind of like cleaning up a giant, gross bathroom!
