Water

This is the best way to get water here unless you want to risk the ill effects of drinking tap water. We've had enough stomach issues as it is, so we choose not to drink from the tap. People here don't really drink tap water, even locals. Water comes in 20 liter containers and costs about $3 each. So when we run out of water,  we call to order more and someone will deliver it to our door usually within 30 minutes. You recycle your empty container for a new one. And when you go out to eat, when you order water to drink, they'll always bring out bottled water.
