A sewage hole is an access point to the underground sewage system where waste and wastewater from buildings and homes are collected and transported for treatment and disposal. These holes are typically covered with a manhole cover for safety and maintenance purposes.
Sewage is whats in the sewer. Sewage is human waste, water, and even rainwater which collects via a sewer and then gets transported through pipes underground to sewage plants.
If you think you smell sewer gas in your bathroom, it could be that a sewage blockage is in your pipes, causing the sewage to back up in the lines.
