According to AWWA standards, how often must all tanks be inspected?

The correct response highlights that, according to the American Water Works Association (AWWA) standards, all water tanks must undergo an inspection at least every five years. This interval is essential to ensure the structural integrity and overall safety of the tanks, which are critical components of water supply systems. Regular inspections help identify potential issues such as corrosion, structural weaknesses, or any other maintenance needs before they become significant problems that could compromise water quality or system reliability.

By adhering to this five-year inspection guideline, utilities can effectively manage their assets and deliver safe and reliable water to communities. This practice also aligns with regulatory requirements and best practices in the field of utilities maintenance, promoting operational efficiency and public health.
