Clean Water Nashville Program

A multi-decade partnership helping reduce sewer overflows and modernize wastewater infrastructure across Nashville.

IDG has provided program and construction management services as a key member of the program delivery team for Metro Water Services’ Clean Water Nashville Overflow Abatement Program (CWN), a large-scale, multi-decade sewer system improvement initiative aimed at reducing sanitary and combined sewer overflow events throughout Davidson County. IDG also contributed design and construction administration services for the Central WWTP Headworks Facility, a $110M, 440 MGD peak-flow facility that replaced two deteriorated grit systems using a CMAR delivery method.
