Driftwood Equalization Facility modifications completed, doubling facility's capacity

The Driftwood Equalization Facility, located on the eastern edge of downtown Nashville, off of Hermitage Avenue on Visco Drive, has been modified to store an additional 3.2 million gallons of combined sewage during peak rain events. This project is a means of reducing or eliminating wet weather overflows during major rain events.

By raising the concrete walls at Driftwood’s open storage facility and installing six new weir gates, CWN has doubled water detention capacity to almost 7 million gallons.

The added capacity is a significant achievement for Cumberland River water quality. Before expansion, the facility experienced an average of six combined sewer overflows (CSOs) into the Cumberland each year. The newly expanded facility is now large enough that hydraulic models project zero CSOs in a typical rainfall year. With the improvement to Driftwood and the recent elimination of CSO discharge locations at Broadway and Van Buren, Nashville has substantially reduced overflows into the Cumberland.
