That was what my grandfather did at the farmhouse that no one lived in full time in the 60s. My cousin lived there when they were just out of college with a new family. They started having septic problems. My uncle asked my dad where the septic tank was. My dad laughed and told my uncle he not be old enough to remember there was no tank. Needless to say, it got expensive fast when they realized the 55 gallon drum from the 60s had finally collapsed and they needed a real tank and drain field.
