Meter readings indicate how much water is being used in a time period. If your bill indicates the reading is an "estimate," contact the Call Center (609-989-3055) to have Trenton Water Works obtain an actual meter reading. Estimated billing only occurs when your meter cannot be read due to severe weather, an inoperable remote reader, or an inaccessible meter. New Jersey State law requires Trenton Water Works to obtain an actual meter reading at least once every six months. When charges are estimated, unnoticed plumbing leaks could remain undetected, resulting in wasted water and increased charges once a reading is eventually done.
