Ang Thong:The Thai Cabinet has approved the Chai Nat-Pa Sak Canal project, aimed at diverting water to the Gulf of Thailand to manage flood and drought risks.
According to Thai News Agency, Mr. Koravee Prisnanantakul, MP for Ang Thong Province and Chairman of the Government Whip from the Bhumjaithai Party, announced the Cabinet's approval under Prime Minister and Minister of Interior Anutin Charnvirakul. The project is considered crucial for long-term water management in the region.
The planned canal will enhance the water diversion efficiency, reducing the burden on the Chao Phraya River, which during flood seasons has historically caused prolonged impacts in several central provinces. Typically, the Chao Phraya Dam manages a maximum drainage capacity of 2,500 cubic meters per second, but existing canals only handle 200 cubic meters per second.
The new canal system is expected to increase drainage capacity by diverting water flow directly to the Gulf of Thailand, cutting the lower Chao Phraya River's flow to 1,000 cubic meters per second. This diversion will help mitigate damage to economic and agricultural areas.
The project involves excavating a new canal parallel to the Chao Phraya River to collect water from upper regions such as Chainat, Singburi, Lopburi, and Nakhon Nayok, discharging it into the Gulf of Thailand. It will also serve as a reservoir during the dry season to support agriculture.
The construction is anticipated to take 7-8 years, requiring a substantial budget, Environmental Impact Assessment, and public consultations. Mr. Koravee expressed confidence that, with proper communication of its benefits, the project will enhance Thailand's water security.
