The name &#8220;Cheonggiwa&#8221; was inspired by Korea\u2019s iconic blue-tiled roofs, often seen in historic architecture like Cheong Wa Dae (the Blue House). Hard to imagine, but before this station, drivers had to carry fuel in cans and manually pour it into their cars\u2014what a hassle! Cheonggiwa revolutionized the fueling process, becoming a game changer for drivers.

Buried about 0.6 to 1.2 meters below the surface, these underground tanks can hold up to an impressive 50,000 liters of fuel. To put that in perspective, an average passenger car fuel tank holds just 40 to 60 liters, meaning a single underground tank could refuel over 1,000 cars!<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'Nanum Gothic', sans-serif; font-size: 13pt;\">Safely storing such vast quantities of fuel is no small feat. Underground tanks must be installed on solid ground to prevent shifting or tilting, and they are designed to withstand hazards like earthquakes, explosions, and environmental risks. Their flawless operation is supported by multiple safety systems, including <strong>overflow prevention systems, leak detection sensors, alarm systems, and tank sumps<\/strong>*. Once stored, the fuel is drawn up by <strong>motor pumps<\/strong> and transported through <strong>dedicated pipelines<\/strong> for gasoline, diesel, and kerosene, eventually arriving at the fuel dispensers\u2014and into your car.<br \/>\n<\/span><em><span style=\"font-family: 'Nanum Gothic', sans-serif; font-size: 10pt;\">(*) Tank sump: A containment unit made from corrosion-resistant material, installed at the manhole or base of underground fuel tanks.

Yet remarkably, no major accidents occurred at gas stations. So, how do underground fuel tanks remain safe even during strong earthquakes?<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'Nanum Gothic', sans-serif; font-size: 13pt;\">The answer lies in <strong>double-walled<\/strong> storage tanks! Think of them like vacuum-insulated thermoses: there is an empty space between two layers, making them exceptionally resistant to external impacts while preventing fuel leaks. The inner layer is made of durable steel, but since steel can rust over time, it is reinforced <strong>fiber glass reinforced plastic (FRP)<\/strong> or <strong>high-density polyethylene (HDPE)<\/strong> to ensure long-lasting protection.
