- Quang Binh Water Supply Joint Stock Company (UPCOM: NQB) is a Vietnam-based utility enterprise primarily engaged in the exploitation, treatment, transmission, and distribution of clean water for residential, commercial, industrial, and administrative consumption across Quang Binh Province. The company operates through several integrated business segments and offers a comprehensive portfolio of water utility products and technical services, which includes: municipal tap water treatment and supply; production and commercial distribution of purified bottled drinking water; construction, installation, and engineering of water supply networks, drainage systems, sewerage facilities, and urban technical infrastructure; consulting, surveying, engineering design, and construction supervision for water treatment facilities and environmental sanitation projects; wholesale and retail trading of specialized plumbing materials, high-density polyethylene (HDPE) pipes, valves, fittings, and industrial water accessories; and calibration, inspection, testing, maintenance, and repair services for water meters and flow measurement instrumentation. The company serves as the dominant clean water utility in north-central Vietnam, managing an extensive distribution network across Dong Hoi City, Ba Don Town, and the districts of Minh Hoa, Quang Ninh, Le Thuy, Bo Trach, and Quang Trach. In recent corporate developments, the company became an associate company of Binh Duong Water Environment Joint Stock Company (BIWASE) after BIWASE acquired a 41% strategic equity stake, creating an operational alliance that links upstream raw water extraction and production—including regional projects connected to BIWASE Quang Binh and the Vuc Tron reservoir—with NQB's municipal distribution network. Furthermore, the company has executed key infrastructure modernization initiatives, including capacity enhancements and operational upgrades at the Phu Vinh Water Treatment Plant alongside the progressive deployment of digital pressure and flow monitoring technologies across its transmission pipelines to optimize operational efficiency and reduce non-revenue water losses. Founded in 1992 and equitized into a joint stock enterprise in 2015, Quang Binh Water Supply Joint Stock Company is headquartered in Dong Hoi City, Quang Binh Province, Vietnam.
