Traders in Penang were reminded not to raise prices of water containers and bottled water ahead of a scheduled water supply disruption from Jan 10 to 14. The State Domestic Trade and Cost of Living Ministry deputy director stated enforcement action could be taken against those who violate price control laws. The water supply disruption will affect 590,000 consumers in Penang due to major valve replacements at the Sungai Dua Water Treatment Plant.
