Answer:
1. Take quick showers, I know that hot water feels good on your back but you gotta turn that knob off.
2. When brushing your teeth, for gods sake, please turn the water off when you put the toothpaste on.
3. STOP FLUSHING THE TOILET REPEATEDLY AND USING IT AS A WASTE BASKET! You have a trash can, stop putting things that don't belong in the toilet, in the toilet. Put them in the trash. It's not even hard!
