Currently, some residences have water meters and are receiving usage-based bills. The remaining residences will have water meters installed in phases over the next seven years. State law requires residences constructed after 1992 to be billed on a usage-based system by January 2011. The Lodi City Council is aware that two different water billing structures will occur for a period of time. Therefore, the Council chose to minimize the time period that the two billing structures would occur.
