This is the formula used to calculate your sewer charges: 1. Start with water consumption values(in thousand, i.e. "15" represents 15,000 gallons)for November on the December bill; December on the January bill; January on the February bill; and February on the March bill.
2. Drop the highest consumption of the above four months
3. Add the remaining 3 months’ consumption, divide by 3 to find the average
4. Multiply the result by .90
5. Subtract 1(as in 1,000 gallons)from the value obtained in step 4
6. Multiply the value in step 5 by $7.44
7. Add $8.60 to the value from Step 6 (to account for the 1,000 gallons subtracted from step 5 to get the new sewer rate.
The maximum monthly residential sewer charge is $75.00 and the minimum is $8.60.
