I agree with comments below, Look around your house and determine those activities that require water. In low water availability areas things like zero scaping. Eliminating grass and outdoor plants, do not wash vehicles, Bath on a schedule and timed. collect rain water in areas that this is legal. use water conservative toilets, There are water conserving faucets and appliances also. There are things that can be done without money like placing a brick into the tank on a toilet to not allow for as much water consumption. Don't let water run. Honestly these things should be done even when water is not scarce. It is our responsibility to conserve and protect these resources.
