The ground was already sinking more slowly before the pumping ban took effect in 2023, so the rule inherits a trend it cannot claim. Of 496 audited buildings, 70 still drew on wells as well as pipes.

Geodesists at Bandung Institute of Technology have tracked Jakarta sinking since the 1970s using levelling, GPS and InSAR, measuring typical rates of 3-10 cm a year between 1974 and 2010 and, by the city's count, up to 20-28 cm a year at certain locations, driven largely by groundwater pumping alongside construction loads and natural compaction. Governor Regulation 93/2021, in force since 1 August 2023, bars buildings of 5,000 m2 or eight floors and above inside nine designated areas and twelve road segments from pumping, and requires calibrated meters reporting into the water agency's system. By February 2024 the agency counted 396 of 496 qualifying buildings on piped water; 70 still used both. In April 2025 it began consulting on extending the zones to three more areas in North Jakarta.

Live 📅 since 2021

📊 Impact

Of 496 qualifying buildings audited by February 2024, 396 had switched to piped water, 70 still used both sources and 5 remained on groundwater alone; the rest, per the agency, relied on tanker deliveries or had not reported their supply. PAM Jaya piped coverage reached 80.24% of Jakarta at the end of 2025.

🎓 Lesson

Jakarta's subsidence had already slowed before the ban commenced — peer-reviewed InSAR puts the 2015-2020 rate near 3 cm a year — so the rule inherits a trend it cannot claim to have caused. A pumping ban is only as strong as the pipe next to it: buildings still fall back on wells when supply falters.
