Professional Tank Inspections

Routine inspections can ensure your tank operates at its best for many years. Greatario offers a full range of services including exterior drone inspections, full interior ROV inspections, and cathodic protection testing. Usually these inspections can be completed while your tank remains ONLINE and IN SERVICE. 

Each inspection also comes with a complete report of all findings and a predictive maintenance schedule to help plan and budget. Our professional team has been building and inspecting tanks for 35+ years and can not only foresee potential issues but can complete repairs and upgrades.

We have built hundreds of tanks across Canada. Our team knows how to build and maintain tanks, and can see beyond the obvious during inspections. Plus, our team can help plan for or immediately resolve any issues that may be present.

The report will outline the timing of inspections, cleanings, cathodic protection testing and replacement schedule. In addition, our plans contain the costs related to each service, by year, to help you plan your budget, or downtime, if necessary. All of our recommendations take into account AWWA standards and manufacturers’ standards.
