Target: 50% reduction in piped water usage by 2030 compared to the 2003 baseline.
Result: In 2026, a 31.38% reduction in piped water usage was achieved compared to the 2003 baseline, due to the implementation of water conservation measures and the installation of eco-sensor water-saving appliances.
Monthly water consumption rate (cubic meters) for 2025: ranging from 2.11 to 2.72 cu.m/capita-monthly, with an average monthly rate of 2.40 cubic metres per capita.
Water consumption rate (cubic meter) from 2003 – 2026, with an average of 29.05 cubic metres per capita per year (based on 2019–2025 data).
