Winter Sewer Averaging
During the drier parts of the year (late spring, summer, early fall) not all household water consumption is going into the sewer system. The City recognizes water for gardens, landscaping, etc., goes into the ground or the drain at the street. Therefore, your billed sewer consumption during this time period is based on your average winter consumption. (City Ordinance No. 2023-16)
