The Energy Ministry's secretary is overseeing round-the-clock digging at the Rama 3 drainage line near Fuel Road after oil mixed with water was found in an old drain. Officials say the cause may involve the pipeline running under a railway, nearby park renovation, or other construction. No cause or repair timeline is confirmed. For businesses working near Rama 3 or Fuel Road, expect road digging and possible access disruption; check site safety and any drainage or oil-contamination issues on your premises.
