上げられた地下水が用いられることもある。2. Description of the Related Art In Japan, most of domestic water such as drinking water, agricultural water, industrial water and the like are provided by river water. Since the water of such rivers needs to be supplied throughout the year without any shortage, they are stored in storage dams constructed using mountains or in reservoirs (regulation ponds) directly connected to irrigation canals. In addition, as industrial water, groundwater pulled from the ground may be used.

発生する。However, the amount of water stored in a storage dam or a reservoir is limited, so that when a large amount of water is used during the drought season, water shortage occurs, and water for domestic use and agriculture is used. -A situation arises in which the use of industrial water must be restricted. In addition, during the drought period, the water quality in the water in the storage dam or the reservoir becomes poor due to the stagnant flow of water. In particular, when rain does not fall during the rainy season, the tendency becomes remarkable. On the other hand, if industrial water is provided by groundwater, problems such as groundwater depletion and land subsidence occur.
