A study on adaptive drought management policy to drought stages : focused on the non-structural measures at local scale
Consecutive low rainfall from 2014 to 2015 had lowered the level of Bo-ryeong multi-purpose dam at Chung-nam Province below 20% in the fall of 2015. Eight cities whose municipal water is supplied from the Bo-ryeong dam had to restrict the water supply. Although the Government had prepared the drought since early 2015, it focused mainly on the agricultural drought prior to the coming rainy season. However, the drought were still prolonged after the rainy season, and the response measures on the municipal water drought were far insufficient. The preparedness for the municipal drought was initiated just before the water supply restriction and the countermeasures lacked of systematization and effectiveness. Although the monetary incentive was provided to customers based on the curtailed amount of the domestic water use, its impact on water conservation was temporarily. The restriction of water supply did not consider either the water-use characteristics or the water conservation potential of different cities.
Desalination and wastewater reuse are climate-proof or drought-proof water resources. Rainwater harvesting or grey water reuse can be used in drought if they are constructed at sufficient scale. Those alternative water resources require massive capital investment, and the large-sized plant is preferred for 'economies of scale'. While the public support for the investment on the alternative water resources is high during the drought, it rapidly diminishes as the drought is relieved. Therefore, the development of the alternative water resource should pass through the scrut
