At the request of a customer or user, a meter shall be tested for accuracy in measuring water consumption. A testing deposit as established by resolution of the City Council shall be paid by the customer or user prior to testing. If the test reveals that the meter has been registering consumption in excess of three percent of actual consumption, the customer or user shall be credited an overcharge to the extent of the error for a period not to exceed four months (120 calendar days) prior to the test and the testing deposit will be refunded. If the test reveals that the meter has been registering consumption less than three percent of actual consumption, the testing deposit will not be refunded. (Ord. 88-23 §25, 1988).
