Ewing Creek Equalization Facility is Operational

Construction of the Ewing Creek / Brick Church Equalization Facility, which consists of a 10.6 million gallon, pre-stressed concrete tank and an 18-million gallons per day wet weather pumping station, is complete and operational. The facility is located near Interstate 24 and Briley Parkway.

The storage tank is utilized when sewer ﬂows exceed the capacity of the existing sewer system. Peak ﬂows are pumped out of the system and stored in the tank until the ﬂows in the system recede. Then the stored volume can be conveyed through the system for treatment. Prior to the construction of the Ewing Creek/Brick Church Facility, ﬂows in excess of the system capacity resulted in sanitary sewer overﬂows.

The project, which began construction in 2017, is related to other Clean Water Nashville projects to address sewer system limitations in the North Fork of Ewing Creek area, located in Metro Council District 3. These projects include:

• The Westchester Drive Rehabilitation project, completed in 2015, renewed approximately 3,850 linear feet of 10- and 18-inch diameter sewer pipe along and crossing the North Fork of Ewing Creek, a tributary to Whites Creek. The rehabilitated infrastructure addressed leaky pipes in the system.

• The neighboring Brick Church Pike Pipe Improvements project, located south of the Westchester Drive Rehabilitation project, was completed in 2018. It included installation of approximately 9,400 linear feet of 24- to 30-inch diameter gravity sewer pipe, 500 linear feet of small diameter sewer pipe, and associated manholes.

The facility is among several Clean Water Nashville Overflow Abatement Program projects completed in recent years in the North Fork of Ewing Creek area to renew infrastructure and reduce sanitary sewer overflows.
