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.

Summer Sewer Average (SSA) Single Family Homes only.
In the Summer, from June 15 to September 15 we give you a break on the sewer volume (because you are using more water outside). The system looks at your normal use from Dec-May and charges you an average for the sewer volume.
Sewer volume charges from September 16 through June 14 are billed at the normal rate of $7.43 per 100 cubic feet of water.
