Summer Sewer Averaging (SSA)
During the summer months, the City understands not all water consumption is going into the sewer as household waste water. The City recognizes water for gardens, landscaping, etc., goes into the ground or the drain at the street. Therefore from June 15th to September 15th of each year, sewer consumption rates are based on average winter consumption.
