摘要

For more than 50 years, the First Utility District of Knox County, TN, has served residents and businesses in the southwestern portion of the county and the town of Farragut. From a small pumping station placed in operation in 1955 capable of pumping about 500 gallons of drinking water to about 700 customers, the district has grown into one of the state's largest water and waste-water utility districts, last year supplying 3 billion gallons of water to nearly 26,000 customers.
