Why do people waste water

My neighbor turn on the motor and never turn off. Every single day it will running for hours and someone have to remind them. Today it was literally running for 3 hours. They just turned on the motor and went to sleep. We had to call them everyday to remind them to turn off. They don't have any guilt for wasting water. It's not that hard to keep alarm when turning on the motor. There are also devices to turn off motor automatically once the water is full. Please don't waste water. Is this happening everywhere in chennai ?
