This service utilizes a sanitized ROV with video camera and recording equipment to inspect all surfaces of the tank below the water level. This visual inspection process is applicable in several industry standards including NFPA 25, AWWA, and is the perfect solution for evaluating coating integrity without removing the tank from service. Thompson Tank recommends having your epoxy coated water storage tank inspected every 3-5 years. Whether you need a periodic inspection, review of a structural concern, or analysis of your tanks service life, TT&C can fulfill your inspection requirements.
