What is the inspection interval for water storage tanks with corrosion protection?

The inspection interval for water storage tanks with corrosion protection is set at 5 years. This timeframe is based on industry standards and regulations that aim to ensure the integrity and functionality of water storage systems. Regular inspections help identify potential corrosion issues that could compromise the tank's structural integrity or the quality of the water being stored.

A 5-year interval strikes a balance between allowing enough time for initial corrosion protection measures to be assessed while ensuring that any emerging issues can be caught before they develop into more serious problems. This frequency is particularly important in a variety of scenarios where the tanks may be subjected to fluctuating environmental conditions that could affect their protective measures.

Other intervals, such as 3 years or 10 years, may not provide adequate oversight or may be unnecessarily frequent, leading to increased maintenance costs without a proportional increase in safety or reliability. An annual inspection is generally too frequent for tanks with effective corrosion protection in place, making the 5-year standard a practical approach for maintaining oversight without overburdening resources.
