2012 Wastewater Service Rates For Cottonwood
0 to 5,000 Gallons - $43.71Base Fee
5,000 Gallons and up - $43.71 Plus $5.07/1,000 gallons
Here’s how wastewater rates are calculated:
If you used an average of 5,000 gallons of water or less during the previous year’s winter months, your monthly bill for wastewater services is a flat rate of $43.71 per month for the following year.
If, however, your household average winter water usage for the previous year was over 5,000 gallons per month, there is an additional charge of $5.07 for every thousands gallons above the 5,000. This $5.07 per thousands of gallons over the 5,000 is added onto the base rate of $43.71.
For example if during the previous winter your household used 5,000 gallons or less as a monthly average, your monthly wastewater bill will be set at $43.71 for the year.
In the case of a household that used an average of 7,000 gallons of water per month in the previous winter, their monthly wastewater bill (2 x $5.07 plus $43.71) would be $53.85 for the year.
Note that all new customers (without a previous winter’s water usage history) will be billed at a flat rate of $43.71 per month. Once the customer has a winter water history, their monthly wastewater rate will be adjusted accordingly for the following year.
