PWA chairman Chirachai Moonthongroi said that this was the first time in 37 years since the PWA started operational that it openly warned the public to use water sparingly and, at the same time, took precautionary steps to ensure sufficient tap water for consumption throughout the long hot season.
He disclosed that the PWA had been spending three billion baht to resolve water shortage for short, medium and long-terms. These include dredging of artesian wells and securing new raw water sources, he said.
Mr Chirachai said that the two-day water cut by the Thanyaburi waterworks unit in the middle of last year was a wakeup call for anticipated acute water shortage in the upcoming dry season.
51 waterworks units in 31 provinces are at risk of running short of raw water to be processed into tap water as the water level in the four major dams which are the main sources of raw water for making tap water has dropped to critical point.
