How to Calculate Sewer Bill

Please print these instructions and then click on the calculation sheet 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 are billed in “ccf” you must first convert to gallons by multiplying “ccf” by 748.  If you are billed in gallons, you do not have to do the conversion.

1.    Look at each of your water bills designated in the worksheet (November, 2015 through April, 2016).  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 in cubic feet (CCF), multiply the total x 748 to get the correct number of gallons.  If the total is in gallons you can skip this step.

3.    Multiply the total gallons x 2 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 are 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 B.

6.    Multiply the number on Line B x .025 to get the correct overage amount.

7.    Add this total to minimum of $280 to get the correct sewer calculation.

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