This project focuses on upgrades to the existing 2.4 acre evaporative sewage lagoons, located north-east and outside of the Materials and Fuels Complex (MFC) fenced area. These existing lagoons are currently at capacity with the approximately 800 personnel based at MFC. The number of researchers and operations personnel at MFC is projected to increase to 1150 personnel by 2020 and to 1500 in later years. This project supports designing new evaporative sewage lagoons to meet the needs of 1500 employees.
