Usually we try not to drink the tap water. Like last week, it was mixed with raw sewage. When we opened the tap and it smelled like sewage and then sewage came out of our water tap. The raw sewage came out of our water tap for seven days. Even when there is not actual sewage coming out of the tap, we know the water quality is not good. But at times we have no choice and we have to drink it anyway.[21]
