In general, it is possible to minimize the damage caused by rain through rapid drainage on the surface even if heavy rain occurs to ensure a good drainage system.

However, the rapid drainage of rainwater can lead to flooding of the rivers, resulting in severe flooding. In addition, there is a side effect such as causing the depletion of groundwater as rainwater does not allow time to fully penetrate into the surface.

Nowadays, to prevent such a phenomenon, a space for storing rainwater is stored in the basement to store rainwater so that people can use it as living water if necessary, and delay the time that rainwater flows into the river. It prevents flooding due to flooding and provides groundwater sources by providing time for the stored water to be absorbed into the surface.

The excellent storage tank provided for this purpose mainly utilized PC concrete, polyethylene, galvanized steel sheets, foamed rolls, and assembly rubble.
