Pay My Bill
Tennessee Wastewater recently partnered with Fiserv to enable paperless delivery of checks by most major banks' billpay services. This drastically reduces check processing time and helps our customers better anticipate when their checks will clear.

TWSI has updated statewide and Williamson County bonding rates effective September 1st (October 1st billing cycle) to reflect the latest TRA mandated true-up. These rates are expected to remain in effect until the next true-up period, which is currently projected to be the same time in 2018.
All Adenus Utility Customers are now able to manage their accounts online! This includes checking your balance, viewing payment history, and making online payments. It's all part of our newly enhanced customer care section of the site. Give it a try by clicking the link below.

"Providing affordable wastewater service in communities where it is presently unavailable."

This has been the mission of Tennessee Wastewater since 1993 and continues to be, as we have established service territories in over 30 counties across the state. Our technology allows development to occur in locations where traditional sewer cannot exist due to financial, physical, or political constraints.

We are more than a wastewater utility. We are a solutions company with the operational and regulatory expertise to navigate through all aspects of a project's watershed/wastewater design and development. We are also the single largest holder of TDEC-issued State Operating Permits (SOPs) in the state. Our associate design/engineering department has a national reputation for solving challenging sewer problems and completing projects on time and under budget. Our technology has provided solutions for a diverse range of projects, including:

school systems
mountain cabins
lake homes
state parks
traditional subdivisions
non-traditional (clustered smart growth) subdivisions
commercial stripmalls

As the flagship utility in our industry, we take our leadership role seriously and are active in policy making within the agencies that regulate us and others like us. We support industry groups like TOWA, educational initiatives like the Center for Decentralized Wastewater Management at the University of Tennessee-Knoxville, and the development of the level-5 RME Model as outlined by the Environmental Protection Agency.
