Recently, as the importance of water resources has increased due to changes in the environment due to industrial development and population growth, it is known that many developed countries are putting enormous budget and effort into securing enough water resources.

As part of efforts to secure such water resources, for example, mainly in European advanced countries, there are few cases where direct water is taken directly for the production of tap water, and radial dust collecting is installed on the lake or river side, The riverbed filtration method has been making efforts to use fewer possible chemicals in the purification process.

Typically, radial collectors have the advantage of pumping large quantities of water from the aquifer and can even increase the rate of water inflow from aquifer to aquifers and sediments, In Korea, there is an increasing tendency to introduce radial house correction.
