City of Wichita Falls Emergency Direct Potable Reuse

The city of Wichita Falls is facing a water shortage crisis due to ongoing drought conditions, with rainfall levels significantly below normal over the past several years and record high temperatures. The city's lake levels have declined as a result. To address the problem, the city implemented drought restrictions which reduced water demand, and also pursued a solution of direct potable water reuse to further cut lake water usage. This direct potable reuse project has helped extend the city's lake water supply by an estimated 12 to 24 months.
