Usually when water meters are placed on a home, they are used to measure the amount of water specifically used by a particular residence for billing purposes because a meter is an accurate way of measuring the use of a utility such as water. Meters are also a good device for trying to conserve the utility being used due to its accuracy.If the water meters being placed on your home are the result of some new company providing this service t the property owners in the trailer park where you live and you will be paying this new company for the water, then if your rent with the trailer park included water per the express terms of the agreement, your monthly rent should be reduced by the amount that you were charged for the water from the trailer park.
