Metro Water Services scores 599 of 599 on state sanitary survey
State regulators' four-day review found no deficiencies, the utility says.
NASHVILLE - Metro Water Services scored 599 out of a possible 599 points on its latest state sanitary survey, according to an Oct. 15 post on the utility's nashville.gov newsroom. The Tennessee Department of Environment and Conservation conducted the four-day on-site review this past month, the post says.
TDEC followed the EPA's Sanitary Survey Manual, which covers eight areas: source water, treatment, distribution, finished water storage, pumps, monitoring and reporting, management and operation, and operator compliance. According to the post, inspectors found no deficiencies and required no corrective actions.
Metro Water scored 99.5% on its previous survey, in 2024, the post says. The utility also plans to begin collecting more water samples starting in October 2026 as its service area grows.
States enforce EPA drinking water rules under the Safe Drinking Water Act and use sanitary surveys to check whether a system can keep supplying safe water.
