Check the bund space for fuel residues or liquid accumulation—signs of inner-tank leaks. Use a dipstick or sensor to monitor for leaks, and periodically pressure-test steel tanks.

Drain water and sediment from the sump daily to prevent corrosion. Inspect and replace clogged fuel filters, and add stabilizers to prevent fuel degradation.

Ensure vents and pressure-relief valves are clear of debris or ice, especially in cold climates, to avoid overpressure or vacuum issues.

Inspect seals for cracks or hardening (especially in cold weather), and tighten loose fittings. Apply anti-corrosive coatings to steel components prone to moisture.

Cross-verify fuel level gauges with manual dipsticks and test low-level/leak alarms weekly. Check smart tank monitoring systems for errors.

Keep absorbent materials on hand for spills, ensure the bund meets capacity regulations, and verify fire extinguishers are accessible.

In cold weather, inspect heating elements and defrost vents; in hot weather, check for sun-induced damage to tank materials.
