How do the petrol pumps get petrol to it?
That's interesting. How are the underground pipes maintained?
The pipes are usually made of durable materials like steel or fiberglass, and they are buried underground to protect them from damage. Regular maintenance of the pipes is important to ensure there are no leaks or cracks that could lead to fuel contamination. Most petrol companies have inspectors who check the pipes periodically to make sure they are in good condition.
