Residential wastewater rates include both variable and fixed charges. Variable charges are calculated from each household’s average water use billed during January, February and March (known as winter quarter average or WQA).
Winter months are used to calculate the WQA because this best represents indoor water use (which typically goes down your drains and into the wastewater system). These charges are calculated each April and apply to bills until the following April.
The minimum WQA is 3,000 gallons (4,000 gallons for duplexes). Customers who haven't been in a residence long enough to establish a WQA are billed based on the rate class average found in the table below.
More than 90% of wastewater costs are fixed. This includes the operation and maintenance of the collection systems and wastewater plants. These costs are calculated annually and apply to all accounts.
There also is a cost to have a connection to the collection system even when not in use, which is averaged over 12 months of bills.
