Mill Creek / Opryland Equalization Facility - Phase II

This project increased the storage capacity of the existing equalization facility through the construction of a 19 million gallon pre-stressed concrete tank that was constructed adjacent to the existing 15 million gallon tank. The storage tanks are utilized when sewer flows exceed the capacity of the existing sewer system. The peak flows are stored until the flows in the system recede, and the stored volume can be conveyed through the system to treatment. Without the construction of this facility, flows in excess of the system capacity resulted in sanitary sewer overflows.
