The inspection process begins with a thorough visual examination of the tank’s external structure. Inspectors assess the condition of the tank walls, roof, foundation, and supporting structures. Any signs of cracks, rust, deformation, or leakage must be carefully evaluated. External coatings and protective layers are also checked to ensure they are intact and capable of preventing corrosion. Environmental factors such as weather exposure and nearby vegetation are considered as they can contribute to long-term damage. Equally important is the internal inspection of the tank. This step often requires draining the tank or using specialized equipment to inspect submerged areas. Inside the tank, inspectors look for sediment accumulation, biological growth, corrosion, and coating deterioration. Sediment buildup can reduce the effective storage capacity and affect water quality, while corrosion can weaken the structural integrity of the tank. Identifying these issues early allows for timely cleaning and repairs, ensuring the tank remains fully functional.
