SOUTHERN ENVIRONMENTAL LAW CENTER
Restoring the Harpeth River
In 2014, SELC and Harpeth River Watershed Association took legal action against three sewage treatment plants along the Harpeth River for ongoing permit violations and excessive sewage discharge in violation of the Clean Water Act. As a result, Harpeth Wastewater Cooperative and Cartwright Creek sewage treatment plants agreed to join a multi-stakeholder effort to restore the health of the Harpeth River. These utilities committed to expanding water quality monitoring in the river, developing a pollution management plan, and joining a diverse stakeholder group to work cooperatively on improving water quality.
In 2016, SELC and HRWA successfully reached a settlement with the City of Franklin. In addition to new protections and monitoring for sewage discharges, part of the settlement agreement is a comprehensive study focusing on the entire Harpeth River watershed, the first such study in Tennessee. This landmark effort, in which SELC will be one of the participants, will assess the health and the risks to the Harpeth River and its tributaries to ensure the river meets water quality standards moving forward.
