Kids learn by doing, and nothing helps make them aware of water-wise practices better than asking them to tag along while you look for toilet, faucet and showerhead leaks. Another good option is to perform a home water audit with them. A water efficiency checklist can help you assess problems in your home and show your kids you mean business when it comes to good water management. You can find a basic checklist on the Environmental Protection Agency's (EPAs) Green Building site: Water Use Checklist. If that's not detailed enough, you might want to consider contacting your local water utility company. It may have a checklist or even an audit kit available for the asking.
