Colleyville – Sewer Charges Calculated During Winter Months

Colleyville – Sewer Charges Calculated During Winter Months
Colleyville uses the winter months’ average of December, January, and February for sewer calculations on residential customers. The
City averages individual household water 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.
Wastewater averaging provides a measure that is generally reflective of the amount of
water that goes directly into the sanitary sewer system from each property. This is generally considered 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
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.
