Tennessee needs over $3 billion by 2027 to repair aging wastewater infrastructure, report finds
(UI) – According to a state analysis by the Tennessee Advisory Commission on Intergovernmental Affairs, Tennessee needs over $3 billion by 2027 to repair, replace, and expand its wastewater treatment systems.
The Tennessee Lookout says the state's aging infrastructure and increasing population are key challenges. Many sewage treatment plants suffer from inadequate maintenance or upgrades. Local governments lack the funds for necessary improvements.
Nearly half of decentralized waste systems don't meet state environmental standards, and numerous local systems face moratoriums from the Tennessee Department of Environment Conservation due to sewage overflow issues. These problems limit their ability to expand, while flooding increases the risk of sewage spills.
The U.S. Environmental Protection Agency has also found Clean Water Act violations in various cities across the state, with Nashville required to make extensive repairs under a court order. The rising population adds pressure on the systems.
The report warns that many wastewater systems lack long-term plans or capital budgets, which could hinder compliance with regulations and future expansions. More investment is needed to address infrastructure deficiencies.
