NEW WATER TUNNEL IN BANGKOK


Construction is underway on a major tunnel on the 9th Bangkok Water Supply


Improvement Project. An update on tunnelling progress on contract G-TN-9B of the water transmission project is provided by Supak Khunviriya, Assistant Vice President (Tunnel), Italian-Thai Development Public Company, and Bunjerd Emnuch, Project Manager, Terratec


PROJECT BACKGROUND Currently, water demand in the western region of Bangkok exceeds the production capacity of the Mahasawat and Thonburi water treatment plants. Additionally, the Metropolitan Waterworks Authority (MWA) has implemented a policy to manage water from the western side of the city to supplement the water supply in the eastern side, where it needs to address challenges posed by saltwater intrusion into the Chao Phraya River.
