Seongnam's total supply capacity is 500,000 m³/day for 1 million residents.

Water Production and Supply Interpretation

K-water’s orchestration of a vast aqueous network—from its major dams supplying a quarter of the nation's water to the silent vigil of millions of smart meters—demonstrates that South Korea's real liquid asset is not just the 7.2 billion cubic meters it delivers, but the colossal, engineered will required to move it efficiently through over 140,000 kilometers of pipeline to ensure 99.2% safety for 23 million taps.

Water Quality and Standards Interpretation

While Korea's water is impressively pristine on paper, from crushing microbial threats to taming industrial pollutants, the real magic is that this scientific symphony translates into a glass of water so clean you could confidently toast to the public health engineers who made it possible.
