Yes, when access, water clarity, internal geometry, and operating requirements are suitable. The ROV is deployed through an approved opening while the operator controls it from outside the tank. Site-specific sanitation and safety procedures should be established before deployment.
Accessible areas may include submerged shell surfaces, floor, seams, columns, braces, ladders, inlet and outlet features, overflow components, and other appurtenances. Coverage depends on tank geometry, obstructions, water clarity, tether management, and safe access.
ROV surveys may be performed in potable water tanks when the equipment, cleaning and disinfection procedures, access method, and owner requirements are appropriate. Final procedures should follow the utility’s water-quality program and applicable requirements.
The video may document visible coating failure, corrosion staining, sediment, debris, biological growth, damaged appurtenances, loose components, and other observable conditions. ROV video alone does not measure hidden section loss or confirm structural capacity.
Typical deliverables include recorded underwater video, representative still images, a description of the inspection route and limitations, and a summary of notable observations with recommended maintenance or follow-up evaluation.
Not in every situation. ROV surveys provide valuable visual information with less disruption, but a drained and cleaned internal inspection may still be needed for direct access, detailed coating evaluation, ultrasonic thickness testing, repairs, or other hands-on work.
