Cumberland City Low Water Main Impact Analysis
Overview
Amid Nashville's rapid economic growth, East Nashville has emerged as a vital hub of development and opportunity. Recognizing that sustainable growth demands infrastructure foundations, Metro Water Services built a second critical 60-inch water main to improve community resiliency.
The centerpiece of the initiative—the Cumberland City Low transmission water main—creates system redundancy, effectively establishing an infrastructure safety net for hundreds of East Nashville homes and businesses. By implementing this parallel delivery system, Metro Water has dramatically reduced vulnerability to service interruptions that could otherwise impede the area's economic momentum and quality of life.
Wilmot’s Role
Wilmot calculated the full range of benefits associated with this infrastructure investment through a triple bottom line analysis. Our evaluation considered key social, environmental, and economic outcomes, including:
Resiliency through a redundant water line
Avoided congestion during construction
Reduced air pollutants and greenhouse gas emissions
Savings through accelerated design and construction
We also assessed the economic impact of capital spending, estimating its contribution to the region’s gross product, job creation, and tax revenue—highlighting the broader value of resilient infrastructure to Nashville’s continued growth.
Results
73.4M in added wealth to the local economy
$1.3M in wasted time and fuel avoided due to the accelerated project schedule
$46,000 in additional social and environmental benefits
