The availability and sustainability of water resources must be maintained to ensure a safe and sufficient supply for people and nature. Sustainable optimization of diverse water resource options conjunctively can minimize over-reliance on existing resources.

In accordance with the National Water Resources Policy, JMG is responsible for identifying potential groundwater resources to support the growing demand for clean water supply. Groundwater sources also need to be identified in sensitive areas in response to disaster prevention such as peat fire. Comprehensive management of groundwater resources will guarantee a continuous supply of clean water and ultimately improve the quality of life of the people and the well-being of the environment.
