Residential Winter Averaging

Northtown Municipal Utility District uses a winter wastewater average to compute an individual's wastewater bill throughout the year. The District will average a customer's three months of water usage starting on November 29, 2017 and ending on February 28, 2018. The average water usage for these three months will become the ceiling under which wastewater will be billed for the rest of the year. These three months are used because the water used during this time period is less likely to be used for irrigation and the resulting wastewater will ultimately be put into the wastewater system.

Once your wastewater average is set, you will be billed on a monthly basis for wastewater at the current rate of $6.89 for every 1,000 gallons of water used up to your ceiling or whatever your wastewater average is computed to be. An example of this would be if your wastewater average is 8,000 gallons and you use 6,000 gallons of water in a month, you will be billed for 6,000 gallons of water and 6,000 gallons of wastewater. If you use more water in a month, then you will be billed for the whole amount of water but your wastewater bill will cap out at what your average is. So if your average is still 8,000 gallons and you use 10,000 gallons of water in a month, you will be billed for 10,000 gallons of water but only 8,000 gallons of wastewater.

There is not a meter to measure the amount of wastewater that you put into the system so this method is used throughout the Central Texas area by many different utility systems. This method allows a customer to save money throughout the year by reducing their water consumption during the winter averaging period. Washing your car, filling a pool or watering your grass during this time period will result in higher water usage and higher wastewater bills for the rest of the year. If you use less water during this time period, you will have a lower wastewater average. This means you will have a lower ceiling for the rest of the year in the computation of your wastewater bill resulting in lower bills for the year as well.
