The decrease in water use can be noted, in part, because of the amount of rainfall Bexar County saw, especially during summer months. In fact, there was just over 8 inches of effective rainfall in the 2021 summer months.
For perspective, in 2022, Bexar County saw just over 3 inches in the same time period (May-September), which will likely increase water use for 2022. While there is no one single factor for reducing water use, weather-related events like less rainfall and days over 100 degrees can aid in increased use of water.
SAWS is currently updating its Water Management Plan, which serves as a guide to meet San Antonio's future water needs. To learn more about this and offer feedback, visit watercitysa.com.
