Engineer: Trousdale County water treatment plants back online; hydraulic model flags low-pressure pockets

Evan White, an engineer with Midten Engineering, told the Trousdale County Utility Board on Oct. 28 that Water Treatment Plant No. 1 is back online and Water Treatment Plant No. 2 is complete.

White said the contractor asked to leave and return to finish work on the pump station at Browning Branch; the contractor expects to complete the remaining work by June next year. White said the firm will bring booster station plans to the state for approval once internal sign-offs are complete.

The engineering teams hydraulic model has identified a number of low-pressure or low-grade pockets in the distribution system. "But the areas that we did find, it's Griev's Hollow Lane. Griev's Ridge Lane. Grama Hill Road as part of it. Hawkins Branch Road at Pequay Hollow Lane. There is Harris Branch Road at the end of it," White said, noting that the model must be calibrated with field measurements before staff can determine whether the readings meet state requirements.

White said field calibration work and pressure verification are on the near-term list of tasks, and staff will report back with measured pressures and any recommended corrective work.

Why it matters: Completed treatment-plant work restores treatment capacity; identified low-pressure pockets can affect fire flow, service reliability and permitting compliance. The board was briefed on the issues and scheduled follow-up verification rather than authorizing immediate remedial construction.

What remains unresolved: Field calibration results and any corrective project scope, schedule and cost were not decided at the meeting.
