Central Wastewater Treatment Plant Optimization
Wilmot is ensuring Nashville’s Central Wastewater Treatment Plant reduces energy use and restores natural ecological function to an urban neighborhood.
Treating up to 200+ million gallons of wastewater a day, the Central Wastewater Treatment Plant in Nashville is the largest of three treatment plants operated by the city’s water department. The capacity of Central is being increased to over 300 million gallons daily as part of the cities long term control plan to reduce combined sewer overflows and modernize aging infrastructure. Nearly every major city across the country is undertaking a similar program in response to Environmental Protection Agency consent decrees. The upgrade will accommodate future flows from downtown Nashville’s combined storm and sanitary sewer system while protecting the Cumberland River and limiting the construction of new tankage.
Wilmot developed a sustainability plan and provided engineering support for the project. In addition to reducing energy usage, the plan will restore 10+ acres of currently paved area to native prairie and build a new community park. The park will increase local recreational acreage, improve community mobility, and enhance livability in the surrounding neighborhoods. Native landscaping will save Metro Water Services money while also enhancing the local community.
