Sewer Usage Averaging
Once a year, the Town of Flower Mound calculates residential water usage to determine residents’ sewer rates for the following year. The new sewer rate will be based on the average water usage during the months of December, January, and February. The procedure begins with a water consumption reading between Nov. 15 and March 10. Below is a chart to determine when your sewer rate will be calculated. The actual read date may occur two to four days prior to the billing date. If your account number begins with:
  • 3 – it will be read from December 1 - March 1
  • 4 – it will be read from December 5 - March 5
  • 5 – it will be read from December 10 - March 10
  • 6 – it will be read from November 15 - February 15
  • 7 – it will be read from November 20 - February 20
  • 8 – it will be read from November 25 - February 25

Minimum Rates
Effective October 1, 2015, the minimum sewer rate is $19.06 for usage from zero through two thousand gallons of water. An additional $3.83 per thousand gallon unit is billed for water usage over 2,000 gallons. Before and during this three month averaging period, residents are encouraged to be aware of water consumption, be conservative with water usage, and check for any possible water leaks.  Small leaks such as a leaking faucet or a leaking toilet can waste up to 180 gallons of water each day, or 5,000 gallons per month. This consumption will not only increase a water bill during this averaging period, but will also raise the sewer rates for the next year. If you have any questions or comments, please contact the Utility Billing Division at 972.874.6010.
