Overview
- As of Nov 2, Johor’s operator Ranhill SAJ reported 81% of disrupted supply restored, with staged recovery across affected districts.
- Close to 800,000 residents experienced unscheduled cuts after several Johor treatment plants halted operations, with tanker deliveries deployed.
- State officials traced the incident to a burst washing pond at a sand‑mining site in Kota Tinggi, with turbidity spiking to about 37,400 NTU versus roughly 400 normally, and Linggiu Dam releases increased to dilute the plume.
- Singapore’s PUB said domestic water supply remains unaffected after ramping up local production, and it will restart the Johor River Waterworks only when raw‑water quality returns to normal.
- Singapore’s NEA said the Johor River contamination and a separate palm‑oil spill were contained at source, and reported normal water quality with no impact to shorelines, fish farms or desalination plants.
