    it has become common practice among people with septic tanks, be them owners or renters, to pour enough grease down their drains to cause a buffer layer to form between their effluent waters and their poop pilings. most septic servicers have even recommended it. so the right-hand picture isnt as bad as it seems. unless youre on city sewer ;)
