폐수 재상용은 Wichita Falls에서 일시적인 물 재사용 프로젝트를 통해 만들어진 물 검사가 재사용 물은 마셔도 안전하다고 계속적으로 보여줌으로써 2014년 4월초에 텍사스로 진출 할 수 있게 만들었다.

프로젝트의 설비는 2013년 12월말에 완성되었고 최근 텍사스 환경 관리위원회에서 요구하는 45일간 엄격한 프로토콜시험을 했고, 긍정적인 결과가 나올 것으로 보인다.

1천300만 달러의 프로젝트는 28,400m³/d의 폐수 중 18,900 m³/d의 식수를 제공한다.

Direct potable reuse of wastewater could be making its debut in Texas, USA, in early May 2014, as testing of water produced by the Temporary Water Reuse Project at the City of Wichita Falls continues to show the water is safe to drink.

The installation of the project was completed in late December 2013 and is currently undergoing an intense 45day testing protocol, as required by the Texas Commission on Environmental Quality (TCEQ).

Assuming a positive result, the US$ 13 million project will use 7.5 MGD (28,400 m³/d) of wastewater to provide 5 MGD (18,900 m³/d) of drinking water (⅓ of the city's daily demand) and is expected to be online by 1 May. The treated wastewater will go to the Cypress Water Treatment plant to blended for treatment with water from Lake Arrowhead and Kickapoo.

Wichita Falls is also "aggressively pursuing" a US$ 35 million Indirect Potable Reuse Project, which will ultimately take all of wastewater to Lake Arrowhead for storage and ultimate use. This project will recycle 1216 MGD (45,000-60,000 m³/d) and will take 35 years to complete. A permit application has been submitted to the TCEQ and right-of-way acquisition has begun.

 

The city already has a membrane plant, the Microfiltration/Reverse Osmosis Plant, which uses Lake Kemp as a water source, providing an additional 10 MGD (38,000 m³/d) of water per day. This was built following the 19992000 drought.

Wichita Falls began pursuing both of the current reuse projects in April 2012 with lake levels just slightly under 60% capacity or Stage 1 of the drought plan. With lake levels currently half that, a Stage 4 drought order is currently in force, with all outside watering using city water banned.
