Commission approves Edge Wastewater LLC to operate in unincorporated county amid debate over decentralized systems
Summary
Maury County commissioners approved an application allowing Edge Wastewater LLC to operate as a wastewater utility in unincorporated areas by an 18-2 vote. The measure prompted debate over failure rates of decentralized wastewater systems and the role of TDEC oversight.
The Maury County Commission on June 16 voted 18-2 to approve Edge Wastewater LLC to operate as a wastewater utility in unincorporated parts of Maury County (O62538). The company must still obtain applicable approvals and permits from the Tennessee Department of Environment and Conservation (TDEC) before installing or operating treatment and disposal systems.
Robert (building and zoning staff) described the vote as an authorization to allow competition in the local decentralized wastewater market: "with competition comes improvements, we hope," he said, adding that TDEC is the agency that licenses and controls the systems.
Commissioners debated the measure at length. Some members expressed concern about articles that described high failure rates of certain decentralized systems in Tennessee; one commissioner referenced a reported failure rate "a little over 50%" in some articles. Robert replied that much of the critical reporting centered on a single provider and that competition could yield better performance and service options.
Other commissioners questioned whether allowing additional utilities could enable denser development patterns; staff noted the countyzoning ordinance still requires minimum lot sizes and that the county has added standards to require redundant design areas, setbacks and additional protections around leachate fields.
The motion to approve Edge Wastewater moved forward after commissioners concluded the county's action authorizes an applicant to operate as a utility locally but does not replace TDEC's permitting and inspection authority.
Why it matters
Authorization allows a local wastewater provider to seek TDEC approval and to compete for projects in the county, potentially affecting development patterns and system performance in rural areas. Commissioners who voted for the measure said competition could improve services; those opposed cited concerns in published reports about failures and the need for rigorous oversight.
Next steps
Edge Wastewater LLC must obtain TDEC approvals and satisfy county zoning and engineering requirements before operating. County staff said additional design standards and setbacks are part of the countyzoning text and will apply to any systems installed.
