Amazing facts-Japanese sewage system

A land known for its creative beauty and artistic landscape, Japan’s sewage system stands apart from any other in the world. The most striking example can be found in the city of Saitama, which features a storm sewer system that is a true work of art.

Typhoons are a dreaded occurrence in this part of the world and to reduce the onslaught of their destruction, the sewer system of Saitama has some unique features.

They are connected by 6.4 kilometers (almost 4 miles) of underground tunnels that lie 50 meters (about 164 feet) below the city’s surface. The sewer system also has a giant tank with 59 concrete columns.

Some 1300 years ago, the city of Heijo-kyo had a drainage system network that ran throughout its borders and five centuries ago, a stone culvert, called the Taiko Sewerage, was built around Osaka Castle and is still in use today.

It wasn’t until the end of World War II, however, that it became a national project to initiate the construction of sewerage systems throughout Japan.
