Our municipal code requires that we issue 12 bills per year. This is best accomplished with 4 billing routes as it takes a full week to process meter reads and issue a set of bills, so we process bills 48 weeks out of the year. This means that once a quarter there are no meter reads or bills processed as well. This takes into account holidays that our offices are closed, resulting in shorter work weeks which makes it extremely difficult to process bills. Due to these 12 bills per year, there are slightly longer and slightly shorter billing periods with a variance of as few as 3 days and as many as 10 days. This means some billing cycles/periods will be as short as 25 days and some cycles will be as long as 38 days.
