Interior Summary / Notes

1. The floor has less than 1" of silt on the floor.

2. The area where the floor meets the sidewall has some corroded spots that are partially blocked by silt preventing a clear view for examination of the corrosion.

3. The patch plate that was welded to the exterior of the tank's sidewall has created corrosion on the interior side.

4. The tank is equipped with cathodic protection around 10' off the floor in the form of 5 blocks of metal. (most likely magnesium)

5. The underside of the roof has moderate corrosion to its structural support beams.

RECOMMENDED MAINTENANCE

Detailed Maintenance Recommendations

Exterior Work

Pressure wash/Soft wash exterior sidewalls: to remove mildew growth to prevent surface degradation.

Repaint exterior surfaces: to address chalking and restore UV protection.

Inspect and coat exterior patch: to verify weld integrity of the new patch and apply a protective coating to prevent rust.

Interior Work

Remove floor silt: Clean out the silt to allow for a comprehensive inspection of the floor and joints.

Inspect floor-to-wall joint: Once silt is removed, perform a detailed visual and ultrasonic thickness (UT) inspection of the corroded spots at the critical joint.

Remediate interior patch corrosion: Clean, blast, and apply an internal coating to the interior side of the patch plate to arrest localized corrosion.

Service cathodic protection: Inspect the five magnesium anode blocks for depletion and replace them if they are no longer providing adequate protection.

Repair roof structural supports: Abrasive blast and recoat the underside structural beams to halt corrosion and maintain structural integrity.

ROV Sterilization Method – Southeastern Tank Inc.

Prior to all tank inspections, the ROV is spray disinfected with a 200ppm chlorine solution per AWWA C652, 4.3.2 Chlorination Method 2, prior to tank entry. Chlorine dosage was per C652, Table 8.2.

All inspections are in accordance with the Tennessee Division of Water Supply Rule 0400-45-01-.17(33) and American Water Works Association standards for inspections of potable water storage facilities.
