What is the recommended action for tanks in areas with high water tables?

For tanks located in areas with high water tables, increasing the burial depth is the recommended action. This is primarily due to the potential for buoyancy effects when the water table rises. If a tank is not sufficiently buried, it can float or move due to hydrostatic pressure exerted by the surrounding groundwater, especially during periods of heavy rain or flooding. By increasing the burial depth, the tank's weight is secured adequately, helping to prevent instability and ensuring that it remains in place under varying water table conditions.

This approach not only mitigates the risk of tank movement and potential damage but also enhances the overall integrity and safety of the installation. A deeper burial may also provide better protection against external forces and environmental impacts that might otherwise cause leaks or structural failures.
