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 to purchase water. The residential sewer rate is averaged based upon the water consumption in the months of December, January and February.
In instituting tiered rates, Southlake joined other communities across the country in recognizing and addressing future water needs. Tiered water rates provide incentive for using water efficiently and discourage non-essential water usage.
