The city provides a water meter to determine how much to charge for water usage and also a place to turn the water off. The meter can also be used as a tool to recognize water leaks. If your water bill dramatically changes and cannot be related to service work, changes in household routines, extra house guests or summer watering, the water meter should be the place to start to determine if there are any hidden water leaks. Obviously, if you have any recognizable leaky faucets, fixtures or toilets, these leaks should be addressed. $TIP$: Many municipalities charge related services (sewage, trash pickup) on the same bill, these charges can be relational to total water usage. If you have leaks you may be giving the city extra money due to a water leak. Look for the upcoming post on Chasing Water Leaks for a leak isolation method.
