Residential sewer is winter averaged. Adding your consumption for December, January, and February billings, then dividing by 3, gives your winter average. The above formula is used to determine dollar amounts. It is then set as a fixed sewer charge from April through March. If you have no winter consumption a 5,600-gallon average is used until changes are completed in April. If you have a leak during the winter averaging usage months, you must have receipts to show repairs have been made for adjustments to your winter average.(6-99)
Example: If average is 2000 gals., rate is $28.19. If average is 8000 gals., rate is $44.93.
