High sea levels in January may impact water quality 

High sea levels in January may impact water quality 

The water authority has said it would increase the amount of water drained from the Chao Phraya Dam when the sea level rises, expected twice in January.

Metropolitan Waterworks Authority (MWA) governor Prinya Yamasamit revealed on Tuesday (January 7) that the sea level will rise on January 13-14 and January 26-27. 
To tackle this problem, the Royal Irrigation Department will increase the water drained from the Chao Phraya Dam from 85 cubic metres per second to 100 cubic metres per second, starting from January 8 onwards.
“During the high sea level, the MWA will reduce the pumping of raw water from the Chao Phraya River for two to three hours,” he said.
“If the high sea level lasts more than three hours, we have to pump raw water to prevent damage to the water canals and that could affect the people’s demand. The tap water will be a little salty at times, especially during high and low tides.”

Meanwhile, the director-general of the Royal Irrigation Department, Thongplew Kongjun, revealed that the combined capacity of water for consumption in the four main dams -- Bhumibol, Sirikit, Kwai Noi Bumrung Dan, and Pasak Jolasid -- was approximately 4,200 million cubic metres.
“The department will drain water in dams nationwide to solve the high water-salinity problem,” he said. “We can confirm that there will be sufficient water for the drought season.”
