How are sewer rates determined?
ACWWA’s sewer rates are formulated using methodologies developed by the Water Environment Federation, a nationally recognized industry group for wastewater industry.

Similar to water rates, the method develops rates based on the cost of providing service to ACWWA’s customer classes (residential and commercial / industrial). Here the cost of providing service depends on the volume of waste discharged to ACWWA’s sewer system, the strength of that waste, and the cost of conducting ACWWA’s Industrial Pretreatment Program. The cost for this EPA-required program is recovered from the commercial / industrial class. ACWWA utilizes "sewer averaging" for its residential customers. In the Spring, after the March bills are issued, ACWWA captures the previous winter's actual consumption for the sewer averaging and that average is what is billed thoughout the summer months. Then in Winter, after the November bills are issued, ACWWA converts to actual consumption for the sewer charges. Sewer charges are meter related and for those customers that do not have a separate irrigation line.

The sewer rate structure also reflects ACWWA’s efforts to promote water efficiency. While customers are charged on the basis of their indoor water usage, they are charged for all water used indoors. So, if less water is used indoors, sewer bills are lower.
