It is important to use water wisely. With so many ways to save water,here are the highlights to help you save water around your home. By following these simple sug?gestions,you will save money on your water bill.

Vegetables and fruit should be washed in a bowl rather than under a running tap and the leftover water can be used for watering plants. Never put water down the drain (排水管) when there may be another use for it such as watering a plant or cleaning.

Avoid washing the toilet unnecessarily. Do not use your toilet as a wastebasket. Take shorter showers. Do not let water running while shaving,brushing your teeth or washing your hair or face. Recently,Singaporeans were urged to shower a minute less as part of a national water conservation effort.

Operate automatic dishwashers and clothes washers only when they are fully loaded or properly set the water level for the size of load you are using.

By thinking carefully about your water use in the home and changing some waterwasting habits,it is easy to save water.
