Winter Quarter Average Conservation
The key to keeping your sewer bill low for the next year if you are a City of El Mirage residential sewer customer is to conserve the amount of water you use during January, February and March.
The sewer fee (a set average) is based upon a fixed charge of $5.27 per month with an additional charge of $3.27 per 1,000 gallons of water used at your home. The sewer fee is determined based upon the amount of water that is used at your home during January, February and March and is called the Winter Quarter Average (WQA). These months are used because they are typically the months when the least amount of water is used outdoors for landscaping, cleaning and maintenance.
Each April, your sewer bill is adjusted based on your WQA. The WQA is the maximum usage you will be charged monthly for the next 12 months.
