How to Calculate Sewer Bill

How to Calculate Your Sewer Bill

Please print these instructions  to determine how your sewer bill was calculated. There are also two examples at the end of the instructions that may be helpful.

The water company bills some customers in cubic feet “ccf” and some customers in gallons. If you’re billed in “ccf” you must first convert to gallons by multiplying “ccf” by 748. If you’re billed in gallons, you do not have to do the conversion.

  1. Look at each of your water bills designated in the worksheet (November PY- through April CY). Fill in either the total cubic feet (ccf) or the total gallons for each month.
  2. Add the numbers up and put the answer on the total line. If the total is the cubic feet (ccf), multiply the total x748 to get the correct number of gallons. If the total is in gallons you can skip this step.
  3. Multiply the total gallons x2 to get the annual water usage and place answer on line A.
  4. If the total gallons (line A) are less than 100,000, your sewer bill is $280 (the minimum) and you’re done with your calculations.
  5. If the total gallons (line A) are more than 100,000 but less than 400,000, you must subtract 100,000 from the total number of gallons and place this answer on line C.
  6. Multiply the number on line C x.025 to get the correct overage amount.
  7. Add this total to minimum of $280 to get the correct sewer calculation.

Less than 100,000, sewer bill is $280
If total over 100,000, but less than 400,000 B 100,000 $280 (minimum)
subtract 100,000 from total gallons C X .025 (overage)
Total Sewer Bill (B+C)
*Water users over 400,000 gallons are billed $7,780.00 for the first 400,000 gallons and .02685 per gallon
in excess of 400,000 gallons.



Example 1 (usage in cubic feet (CCF), less than 100,000 gallons.
Example 2 (usage in gallons, more than 100,000 gallons.
