This institutional organisation affects policy coherence. Water quantity management spills over and is affected by choices made in other policy fields (i.e. agriculture, energy, urban development, public finances), which are often responsible for growing pressures on water resources. The multiplicity of actors involved in water management at central level, and the lack of institutional incentives in Korea (e.g. common objectives, performance indicators, etc.) On the one hand, this approach is well-suited to provide access to bulk water at the same price across the nation.
