- VIWACO Joint Stock Company (UPCoM: VAV) is a Vietnam-based utility company primarily engaged in the distribution and retail supply of treated clean water for residential, commercial, and industrial consumers across Hanoi. Founded in 2005 as the Clean Water Investment Construction and Trading Joint Stock Company and renamed VIWACO Joint Stock Company in 2015, the company operates as a key subsidiary of Vietnam Construction and Import-Export Joint Stock Corporation (VINACONEX), which holds a controlling 51 percent equity stake. Headquartered in Hanoi, Vietnam, VIWACO manages a critical downstream distribution network with a delivery capacity exceeding 200,000 cubic meters per day, serving more than 147,000 customer accounts and accounting for approximately 25 percent of the capital city's water supply market. The company operates across two principal business segments: Water Supply Services and Water Engineering & Equipment Trading. Its core offerings and operations include; the bulk intake, transmission, and retail distribution of potable tap water sourced primarily from the Song Da surface water treatment facility; the construction, operation, routine maintenance, and repair of municipal clean water distribution pipelines, secondary piping networks, and booster pump stations; investment consultation, technical survey, project management, and engineering design for municipal water supply and drainage infrastructure projects; and the trading, installation, and calibration of specialized water equipment, including electronic smart meters, high-density polyethylene and ductile iron piping, valves, and flow monitoring instruments. Geographically, VIWACO focuses its operational footprint within the southwestern districts of Hanoi, including Thanh Xuan, Nam Tu Liem, Cau Giay, Hoang Mai, and Thanh Tri. In recent operational and corporate developments, VIWACO has adapted to multi-phase municipal retail water tariff revisions enacted by the Hanoi People's Committee, alongside upstream wholesale tariff adjustments designed to support the Song Da Phase II capacity expansion to 600,000 cubic meters per day. To accommodate growing urban demand and enhance network resilience, the company has undertaken major distribution system renovations, implementing end-of-network pressure stabilization programs in western urban wards, rolling out digital customer profiling systems, modernizing smart metering hardware to curb non-revenue water loss, and aligning its transmission infrastructure with broader regional green water expansion initiatives across the Hanoi metropolitan area.
