It was initially intended that the construction workers should live off-site, but the poor condition of the roads and a shortage of accommodations in the area made commuting long and difficult, and in turn made it difficult to find and retain workers. Construction workers therefore came to be housed in large hutment and trailer camps. The J. A. Jones camp for K-25 workers, known as Happy Valley, held 15,000 people. This required 8dormitories, 17 barracks, 1,590 hutments, 1,153 trailers and 100 Victory Houses. A pumping station was built to supply drinking water from the Clinch River, along with a water treatment plant. Amenities included a school, eight cafeterias, a bakery, theater, three recreation halls, a warehouse and a cold storage plant. Ford, Bacon & Davis established a smaller camp for 2,100 people. Responsibility for the camps was transferred to the Roane-Anderson Company on 25 January 1946, and the school was transferred to district control in March 1946.
