Winter Sewer Month Calculations in Effect

Post Date:12/06/2018 10:11 AM
Colleyville uses the winter months' average of December, January, and February for sewer calculations on residential customers. The City averages individual household consumption during these months to set residential sewer rates for the year. For households that have no preceding winter months' usage, Colleyville uses an average of 9,000 gallons as set by city ordinance. During the winter months, residents should be aware of all unnecessary water usage, dripping faucets, leaking toilets, etc. to minimize their monthly sewer bill for the following months.


Why does Colleyville average winter month's sewer?

Waste water averaging provides a measure that is generally reflective of the amount of water that goes directly into the sanitary sewer system from each property. The City believes this is the most equitable way to determine the sewer volume.


December, January, and February are used to calculate the sewer average, as that time period provides a true picture of interior water use when water consumption is not impacted by outdoor water use such as filling swimming pools and lawn sprinkler systems.


Winter averaging allows customers the opportunity to lower their monthly sewer bill by reducing water use during winter months and keeps the sewer charges consistent each month.


The calculation process is repeated every year in the same manner. While many households may not see a big change from year to year, some homes may actually see a drop or rise in the wastewater charge because of the calculations from the three month period.
