AWWA (American Water Works Association) recommends inspection of steel storage
tanks every five (5) years, and once a year for pre-stressed concrete structures.
These inspections are highly recommended to assess the exact condition of
the tank and the coatings / linings: The extent of sediment accumulated
(which we can remove underwater); what degree corrosion or pitting has taken
place, and when it will require cleaning, repairing, or recoating. For example,
the inspection might conclude that your tank doesn't require recoating for
two years. You could then plan and budget for scheduled repairs around that
time to minimize inconvenience.

Inspection Pays for Itself
There is no coating that is fail safe. However, it is possible to add years
to the life of a coating system through proper on-site inspection during
the coating process. Since we specialize in protective coatings, we are
experts in why coatings fail and how to avoid their premature failure. Coatings
failures result from many factors, such as not adhering to specifications,
improper surface preparation, mixing errors, application processes, climactic
conditions, etc. Our inspectors ridgedly adhere to governing specifications,
to assure work is accomplished as prescribed. Oftentimes a surface is improperly
prepared prior to coating thus leading to a failure within months, which
leads to a costly repair, recoat and downtime.
