Get or create a dual flush toilet

This is basically a toilet that flushes a smaller amount of water for when you pee and more water for pooping, thereby saving water. Use the half flush button with a dual flush toilet. You can also buy a dual flush conversion kit to turn your water guzzling toilet into a water saver you can be proud of. Search the web for devices like Selectaflush and Twoflush. They both work well and save money.
