One of the most critical services provided by the Alcoa Public Works and Engineering Department is the delivery of safe drinking water. Toward that end, the Water Treatment Plant employees operate Alcoa’s Water Treatment Plant (WTP) located on Sam Houston School Road. With a rated capacity of 16 million gallons per day, the Alcoa WTP is the largest membrane water filtration plant in Tennessee. It serves the City’s 10,000+ water customers (households and businesses) plus the Tuckaleechee Utility District. Water is also provided on an as-needed basis to the City of Maryville and the Knox Chapman Utility District. Plant personnel consistently deliver water that meets all applicable State and Federal regulations.
