Check for water leaks
Fix all leaks. In fact, leaks waste so much water that you should check for leaks. To check for leaks, turn off all water in the house. Next, read your water meter, wait one hour (make sure no water is turned on during this period), and read the meter again. If the meter does not read exactly the same, there is a leak. Fixing leaks you can identify may be as simple as replacing a washer or tightening a connection. If you do have to hire a plumber to locate and/or fix a leak, the money will be offset by the savings on your water bill.
Shutting off the water
To save water in the shower, turn the water off while you lather up. If you're handy, you may want to install a water-control valve on your shower head. The advantage of a valve is that it keeps the water (hot and cold) mixed while shut off.
Turn off the water while you are brushing your teeth and shaving. This will reduce the money that you spend on your water bill every month.
Every penny you save really adds up over a year.
