\n<\/span> Journeying back to the late 20th century, Bachy Soletanche Vietnam took its pioneering steps in hydraulic infrastructure. As the largest man-made reservoir in Vietnam and Southeast Asia, Dau Tieng is a vital “lifeline,” providing irrigation and domestic water for millions in Tay Ninh, Binh Duong, and Ho Chi Minh City. To ensure this “inland sea” remains secure against immense hydrostatic pressure, BSV implemented specialized geotechnical solutions to address critical seepage challenges within the dam body.<\/div>\n
