What load must a tank lid be able to withstand?

The correct load that a tank lid must be able to withstand is 150 pounds per square foot. This standard is often established to ensure the safety and durability of septic tank systems, particularly in areas where heavy traffic may occur.

The 150 pounds per square foot criterion is based on the need for septic tank lids to support not only the weight of the lid itself but also any potential loads from vehicles or equipment that might pass over the tank. This is especially crucial in commercial settings, where maintenance and access are common, and a failure to meet the load requirement could lead to serious safety risks and damage to the septic system.

Other load capacities may be higher or lower, but 150 pounds per square foot is commonly accepted in Georgia's regulations for septic tank lids, reflecting a balance between safety considerations and practical engineering standards.
