API RP 575 - Inspection Practices for Atmospheric and Low Pressure Storage Tanks.

The inspection and cleaning interval can vary based on the type of tank and water quality. Generally, a water storage tank should be inspected at least every five years, or more often, depending on State requirement. Cleaning and repairs should be addressed based on the findings of the tank inspection.

Storing capacity- In general, almost 135 litres of water are required per person a day for everyday usage. Henceforth, 650 litres of water are necessary every day for a family of four people. However, a small water tank is sufficient for a household of four.

API 653 - Tank Inspection, Repair, Alteration, and Reconstruction.

The API-650 Standard is used when the tanks are storing petroleum products. In order to determine when your tank needs to be inspected you must speak with your provincial authority. Typically the inspection intervals occur every 5 years for external inspections and 10 years for internal inspections.

Inspections performed by the DO must be performed at least once every 30 days. The DO may perform an inspection early; however, the following inspection must be performed within the next 30 days. [Reference cited: § 2716(a).]

The API 653 Standard is the corollary to the API 650 Standard. API 650 is for constructing a new above ground liquid storage tank while API 653 is for the maintenance of an API 650 to determine whether the tank fit for continued service.

The most common steel storage tanks for storing oil, vapors, and other organic and non-organic liquids are the API 620 and 650.

API 653 - Tank Inspection, Repair, Alteration, and Reconstruction.

For both scenarios, API 653 states that tank inspection intervals “shall not exceed 20 years for tanks without a Release Prevention Barrier or 30 years for tanks with a Release Prevention Barrier.” This is true for the first and subsequent inspections.

The most common method is using water test strips which changes colour when exposed to water to indicate its mineral content. Different strips are present to test multiple factors by immersing them in the water. After the strip changes its colour slowly, match it with the provided colour chart to get the results.
