Question

Rainwater holding tank covers shall be capable of supporting an earth load of not less than ________ pounds per square foot (lb/ft squared) where the tank is designed for underground installation?

1) 100
2) 200
3) 300
4) 400

Answer 1

2) 200 lb/ft² for a rainwater holding tank cover capable of supporting an earth load for underground installation, which ensures safety and structural integrity.

Step-by-step explanation:

The correct answer is option 2) 200 pounds per square foot (lb/ft²). This standard is related to the structural requirements for rainwater holding tank covers designed for underground installation.

The load capacity ensures that the covers can withstand the weight of the soil above them plus any additional loads that might be applied, like the passage of vehicles or equipment, while maintaining the integrity of the structure and preventing any potential collapse.

This requirement is important for safety reasons and is often specified in building codes and regulations for civil engineering projects.
