- Da Nang Water Supply Joint Stock Company (UPCoM: DNN) is a Vietnam-based utility enterprise primarily engaged in the production, treatment, and piped distribution of clean and potable water for municipal, residential, commercial, and industrial consumers across Da Nang City and surrounding localities. The company operates across several core segments, providing an integrated portfolio of products and services that includes: the extraction, purification, and piped transmission of tap water supplied via major municipal facilities including the Cau Do, San Bay, Hoa Trung, and Son Tra water treatment plants; the production and commercial distribution of bottled purified drinking water; civil and industrial engineering, construction, and installation of water supply pipelines, drainage networks, and wastewater treatment infrastructure; technical surveying, design, consultancy, and project management for hydraulic engineering works; the wholesale and retail trading of specialized plumbing materials, ductile iron and high-density polyethylene pipes, valves, fittings, smart water meters, and electromechanical treatment equipment; and water quality laboratory testing, chemical analysis, meter calibration, and network maintenance services. Tracing its operational history to municipal water systems established between 1945 and 1950, and later formalized as a state enterprise in 1985 before completing equitization in November 2016 and listing on the UPCoM exchange in July 2017, the company is headquartered in Da Nang, Vietnam, with major shareholding held by the Da Nang City People's Committee alongside Da Nang - Central Investment Joint Stock Company. In recent developments, the company has expanded its municipal water supply operations through the integration of the newly commissioned Hoa Lien Water Treatment Plant under an approved municipal operational revenue-sharing framework, and initiated the Southeast Da Nang transmission pipeline development project to enhance interconnection and water security across the Cam Le and Ngu Hanh Son districts. To combat heightened seasonal salinity intrusion at the Cam Le River intake, the enterprise has reinforced operations at the An Trach raw water booster station while executing extensive digital transformation initiatives, including the modernization of its supervisory control and data acquisition network, the deployment of smart non-revenue water reduction programs in collaboration with international utility partners such as Dutch Water Operators, and the adoption of automated digital customer management systems.
