There are a number of factors that determine the rates we charge for water and sewer consumption. Some of those factors include maintenance and operations costs of infrastructure and the cost of purchasing water. The residential sewer rate is averaged based on the water consumption in the months of November, December, and January.
In instituting tiered rates, Southlake joined other communities across the country in recognizing and addressing future water needs. Tiered water rates provide incentives for using water efficiently and discourage non-essential water usage.
